Question 3

What is Modbus and How does it work?

Accepted Answer

What is Modbus? Modbus is a serial communication protocol developed by Modicon published by Modicon® in 1979 for use with its programmable logic controllers (PLCs). In simple terms, it is a method used for transmitting information over serial lines between electronic devices. The device requesting the information is called the Modbus Client and the devices supplying information are Modbus Servers. In a standard Modbus network, there is one Client and up to 247 Servers, each with a unique Server Address from 1 to 247. The Client can also write information to the Servers.The official Modbus specification can be found at https://modbus.org/ What is it used for? Modbus is an open protocol, meaning that it's free for manufacturers to build into their equipment without having to pay royalties. It has become a standard communications protocol in industry, and is now the most commonly available means of connecting industrial electronic devices. It is used widely by many manufacturers throughout many industries. Modbus is typically used to transmit signals from instrumentation and control devices back to a main controller or data gathering system, for example a system that measures temperature and humidity and communicates the results to a computer. Modbus is often used to connect a supervisory computer with a remote terminal unit (RTU) in supervisory control and data acquisition (SCADA) systems. Versions of the Modbus protocol exist for serial lines (Modbus RTU and Modbus ASCII) and for Ethernet (Modbus TCP). How does it work? Modbus is transmitted over serial lines between devices. The simplest setup would be a single serial cable connecting the serial ports on two devices, a Client and a Server. The data is sent as series of ones and zeroes called bits. Each bit is sent as a voltage. Zeroes are sent as positive voltages and a ones as negative. The bits are sent very quickly. A typical transmission speed is 9600 baud (bits per second). What is hexadecimal? When troubleshooting problems, it can be helpful to see the actual raw data being transmitted. Long strings of ones and zeroes are difficult to read, so the bits are combined and shown in hexadecimal. Each block of 4 bits is represented by one of the sixteen characters from 0 to F. Each block of 8 bits (called a byte) is represented by one of the 256 character pairs from 00 to FF. How is data stored in Standard Modbus? Information is stored in the Server device in four different tables. Two tables store on/off discrete values (coils) and two store numerical values (registers). The coils and registers each have a read-only table and read-write table. Each table has 9999 values. Each coil or contact is 1 bit and assigned a data address between 0000 and 270E. Each register is 1 word = 16 bits = 2 bytes and also has data address between 0000 and 270E. Coil/Register Numbers can be thought of as location names since they do not appear in the actual messages. The Data Addresses are used in the messages. For example, the first Holding Register, number 40001, has the Data Address 0000. The difference between these two values is the offset. Each table has a different offset. 1, 10001, 30001 and 40001. What is the Server ID? Each server in a network is assigned a unique unit address from 1 to 247. When the client requests data, the first byte it sends is the Server address. This way each server knows after the first byte whether or not to ignore the message. What is a function code? The second byte sent by the Client is the Function code. This number tells the server which table to access and whether to read from or write to the table. What is a CRC? CRC stands for Cyclic Redundancy check. It is two bytes added to the end of every modbus message for error detection. Every byte in the message is used to calculate the CRC. The receiving device also calculates the CRC and compares it to the CRC from the sending device. If even one bit in the message is received incorrectly, the CRCs will be different and an error will result. . What are the formats of Modbus commands and responses? What are data types? The example for FC03 shows that register 40108 contains AE41 which converts to the 16 bits 1010 1110 0100 0001 Great! But what does it mean? Well, it could mean a few things. Register 40108 could be defined as any of these 16-bit data types: A 16-bit unsigned integer (a whole number between 0 and 65535) register 40108 contains AE41 = 44,609 (hex to decimal conversion) A 16-bit signed integer (a whole number between -32768 and 32767) AE41 = -20,927 (hex to decimal conversion that wraps, if its over 32767 then subtract 65536) A two character ASCII string (2 typed letters) AE41 = ® A A discrete on/off value (this works the same as 16-bit integers with a value of 0 or 1. The hex data would be 0000 or 0001) Register 40108 could also be combined with40109 to form any of these 32-bit data types: A 32-bit unsigned integer (a number between 0 and 4,294,967,295) 40108,40109 = AE41 5652 = 2,923,517,522 A 32-bit signed integer (a number between -2,147,483,648 and 2,147,483,647) AE41 5652 = -1,371,449,774 A 32-bit double precision IEEE floating point number. This is a mathematical formula that allows any real number (a number with decimal points) to represented by 32 bits with an accuracy of about seven digits. AE41 5652 = -4.395978 E-11 Here is a spreadsheet IEEE float calculator for inputs of 4 bytes or 2 words. To download a copy, right click and select Save Target As... A four character ASCII string (4 typed letters) AE41 5652 = ® A V R More registers can be combined to form longer ASCII strings. Each register being used to store two ASCII characters (two bytes). What is byte and word ordering? The Modbus specification doesn't define exactly how the data is stored in the registers. Therefore, some manufacturers implemented modbus in their equipment to store and transmit the higher byte first followed by the lower byte. (AE before 41). Alternatively, others store and transmit the lower byte first (41 before AE). Similarly, when registers are combined to represent 32-bit data types, Some devices store the higher 16 bits (high word) in the first register and the remaining low word in the second (AE41 before 5652) while others do the opposite (5652 before AE41) It doesn't matter which order the bytes or words are sent in, as long as the receiving device knows which way to expect it. For example, if the number 29,235,175,522 was to be sent as a 32 bit unsigned integer, it could be arranged any of these four ways. AE41 5652 high byte first high word first 5652 AE41 high byte first low word first 41AE 5256 low byte first high word first 5256 41AE low byte first low word first What is a Modbus Map? A modbus map is simply a list for an individual server device that defines - what the data is (eg. pressure or temperature readings) - where the data is stored (which tables and data addresses) - how the data is stored (data types, byte and word ordering) Some devices are built with a fixed map that is defined by the manufacturer. While other devices allow the operator to configure or program a custom map to fit their needs. What is the difference between Modbus ASCII and Modbus RTU? Modbus RTU and Modbus ASCII talk the same protocol. The only difference is that the bytes being transmitted over the wire are presented as binary with RTU and as readable ASCII with Modbus RTU. important to note about RTU is that the RTU message does not have a Start_of_text indication. The receiving party in the communications uses a "silent" time in order to determine the start of a new message. ASCII does have a start-of-text token. Binary messages are shorter than ASCII and therefore theoretically faster to transmit/receive. You may be happy to see update rates of about 100 ms in your HMI/SCADA and could choose either communication.Summary:- use RTU is possible- use ASCII in case RTU is giving timeout problems on WinNT or when using slow communications media like 300 bps or dialup modems Most OPC Servers for Modbus support ASCII as well as RTU communications.. What are extended register addresses? Since the range of the analog output holding registers is 40001 to 49999, it implies that there cannot be more than 9999 registers. Although this is usually enough for most applications, there are cases where more registers would be beneficial. Registers 40001 to 49999 correspond to data addresses 0000 to 270E. If we utilize the remaining data addresses 270F to FFFF, over six times as many registers can be available, 65536 in total. This would correspond to register numbers from 40001 to 105536. Many modbus software drivers (for Client PCs) were written with the 40001 to 49999 limits and cannot access extended registers in server devices. And many server devices do not support maps using the extended registers. But on the other hand, some server devices do support these registers and some Client software can access it, especially if custom software is written. How does 2-byte server addressing work? Since a single byte is normally used to define the server address and each server on a network requires a unique address, the number of server on a network is limited to 256. The limit defined in the modbus specification is even lower at 247. To get beyond this limit, a modification can be made to the protocol to use two bytes for the address. The client and the servers would all be required to support this modification. Two byte addressing extends the limit on the number of servers in a network to 65535. By default, the Simply Modbus software uses 1 byte addressing. When an address greater than 255 is entered, the software automatically switches to 2 byte addressing and stays in this mode for all addresses until the 2 byte addressing is manually turned off. How can you send events and historical data? Enron Modbus includes commands for moving events and historical data.. What is Enron Modbus? Enron Modbus is a modification to the standard Modicon modbus communication protocol developed by Enron Corporation. See Enron Modbus for details.

Please note, USB may not allow for a firmware downgrade. You must use a manual method to accomplish a downgrade.2. Create a folder on your USB flash drive called apcfirm .3. From the latest firmware files that you downloaded, add to the apcfirm folder the binary files for the firmware modules that you would like to upgrade. Some examples of the binary files for the three firmware modules follow: Firmware ModuleBinary File APC Boot Monitor apc_hw05_bootmon_109.bin APC Operating System (AOS) apc_hw05_aos_712.bin Application Module apc_hw05_sumx_712.bin Language Pack* sumx_712_frFrdeDeruRuitItesEs.lpk *Optional language pack upgrades/changes are supported via USB if the device you’re upgrading already has BootMonitor v1.0.8 or higher (BootMonitor performs the upgrading function). NOTE: Not all NMC2 applications support language packs. 4. Use a text editor such as Microsoft Notepad to create a file called upload.rcf. NOTE: (Ensure that file extensions are visible so that your file does not get named upload.rcf.txt. In Windows, this option can be edited in Folder Options->View->Hide extensions for known file types within Control Panel. Make sure that option is unselected.) Add to the file a line for each firmware module that you want to upgrade as shown below (replace “xx” with the version of firmware you will be upgrading to): BM=apc_hw05_bootmon_xx.binAOS=apc_hw05_aos_xx.binAPP=apc_hw05_sumx_xx.binLANG=sumx_xx_frFrdeDeruRuitItesEs.lpk 5.

Question 8

What does B,C,D curve mean for Acti 9 MCB?

Accepted Answer

B Curve means the MCB trips between 3-5 times full load current. It is mainly used in residential applications where loads are resistive e.g. lighting fixtures, domestic appliances with low surge Levels.C Curve means the MCB trips between 5-10 times full load current. It is used in commercial/industrial applications where there is greater chances of higher short circuit currents e.g. mainly inductive loads , fluorescent lighting.D Curve means the MCB trips between 10-14 times full load current. It is used where inrush currents can be very high e.g. motors, X-ray machines.Here is the curves diagram:

Question 9

What does the term "NEMA Type 1A" refer to?

Accepted Answer

NEMA Standards Publication 250-1997, "Enclosures for Electrical Equipment (1000 Volts Maximum)" no longer lists this enclosure type. This enclosure type is commonly accepted to be referring to a NEMA 1 enclosure with a gasketed cover.

Question 10

What is difference between BL and BD coils?

Accepted Answer

The difference between BL and BD Coils is a BL coil has a lower power consumption which is good for a contactor ONLY (no auxiliaries attached). Wherefore a BD coil has a normal power consumption but has the capability to use auxiliaries.

Question 11

Question 12

Why choose Type B RCD for 3 Phase Variable Speed Drives?

Accepted Answer

For the 3 Phase Variable Speed Drives, the RCD type B or type B-Si is particularly suitable.It protects against fault currents with DC offset, which is true for three-phase power converters. In addition, it has enhanced immunity against nuisance tripping caused by: EMC common mode filters connected upstream VSD.Type B has a tripping delay allowing the inrush current to flow on power up.The permanent switching leakage currents existing in power converters (ex: 25kHz).Type B includes a "low pass" filter to ensure a trigger threshold that increases with frequency while complying with the personal protection curve (fibrillation). Please note: if the required sensitivity is 300mA, Selective type RCD should be proposed ensuring a non-triggering time of 50ms. More information can be found on the Earth Fault Protection guide: https://download.schneider-electric.com/files?p_enDocType=Catalog&p_File_Name=CA908066E+%28web%29.pdf&p_Doc_Ref=CA908066EWith regards to installation of these RCDs, they are mounted upstream of the Variable Speed Drives.See below example Schneider Electric offers Acti9 iID range of 4 Pole RCDs type B available in 30 mA sensitivity and type B-Si available in 30 and 300 mA sensitivity (Selective type is available) Click this link below to view the complete range of Acti9 iID RCDs available in Australia: https://www.se.com/ww/en/product-country-selector/?pageType=product-range&sourceId=7559&N=781354987+3098582207+2355967283+39384534

Question 13

How can I cable to the PNP and NPN type outputs for sensors / detectors, using the wiring diagram?

Accepted Answer

PNP and NPN type outputs are available as 3-wire sensors with a DC voltage power supply (the voltage limits are dependent on the specific sensor): PNP type: switching on the positive voltage load NPN type: switching on the negative voltage load These outputs are typical of photoelectric detectors, inductive proximity and other types of sensors.For a detailed explanation of PNP vs NPN, see the following FAQ: FA142566 PNP output The load (relay coil, contactor relay input, PLC input) must be connected between the "-" negative terminal and the midpoint. The corresponding PLC input is Sink. NPN output The load must be connected between the "+" positive terminal and the midpoint. The corresponding PLC input is Source. Some sensors have two PNP and NPN outputs (4-wire sensors) which are wired according to the diagram below.Note that we no longer sell sensors. Telemecanique Sensors, who were previously part of the Schneider Electric brand, were sold in 2023. You can go to their website - www.telemecaniquesensors.com - for more information, including contact details.

Question 14

What is the selection criterion of Circuit Breakers for the Capacitor bank application.

Accepted Answer

The selection should be done after derating the Circuit Breaker taking into consideration voltage variation and capacitors tolerances that could increase nominal current up to 1.5In. The Derating factor of 1.5In Where In = Q/ ( Square root of 3 ) Un Q = Capacitor Power Un = Nominal Voltage Choose the Micrologic with delay time selection, so that the Circuit Breaker does not trip due to initial high inrush current. Also to be taken into account are the parameters like supply frequency, operating voltage & harmonics level of the power system for such application. Refer the attached sheet for further details for selection of Circuit Breaker for Capacitor duty application. Note: Use the phase barrier between the phases in Circuit Breaker to prevent flashover due to heavy inrush current.

Question 15

What are the effects of dV/dt on a Motor when using a VSD?

Accepted Answer

As there is an impedance mismatch at the termination of the motor cable to the motor, there will be a reflected wave which travels back along the motor cable causingovervoltage’s. Overvoltage’s on the motor terminals can cause both partial and corona discharge which eventually wears down the winding insulation to failure. Corona discharge occurs when the overvoltage is large enough to cause electrons to flow from one winding to another whilst ionising the air between the conductors. They cause damage to the internal and external insulating material respectively. As the motor cable length increases the peak voltage increases. This can increase to a value of 2 to 2.5 times the DC bus voltage. Schneider Electric Offer Sinus filters or dv/dt filters to reduce the overvoltage across windings and high frequency currents in differential mode. Check out our current ATV600 or ATV900 catalogue for more information on output filters to help you with overvoltage mitigation.
