How to read timestamped input of a BMXERT1604 module ?

Issue:

How to retrieve the timestamp of an input located in a BMXERT1604T module

Product Line:

BMXERT1604, M580 CPU

Environment:

EcoStruxure Control Expert V16.2, Windows 10

Resolution:

The GET_TS_EVT_M function block gets the time stamped data in:

• BMX ERT 1604T when located in Modicon M340 local drop

• BMX ERT 1604T when located in Modicon M580 local and remote drops

• BME P58 Modicon M580 controller

• BMX CRA 312 10 of a Modicon M580

• BME CRA 312 10 of a Modicon M580

This function allows reading the event buffer to make it available for the controller application:

To launch the communication function only once, the ENABLE signal needs to be reset to 0 after the ACTIVE parameter is set to 0. If the ENABLE parameter is maintained to 1 after the ACTIVE parameter is set to 0, the communication function is launched again and the ACTIVE parameter is set to 1 on the next cycle.

If the ENABLE bit is reset to 0 before completion, the function block is stopped (active bit to 0). To have a complete block execution, the value of 1 must be applied on the ENABLE bit until the operation has finished or until an error has occurred.

• The ADR pin must be connected to an ADDMX or ADDM function.
• The BUFFER array will contain the event timestamp entries, retrieved from the BMXERT1604 module.
