How Does a SCADAPack 575 Poll a Vortex Meter
A SCADAPack 575 can be configured to poll the Modbus registers of a Field Devices Vortex meter (model 84CF / 84CN).
As the Vortex meter is a serial RS-485 device a serial port configured for RS-485 on the SCADAPack 575 needs to be selected. In this example Serial3 on the SCADAPack 575 is wired into the serial port connector on the Vortex meter. The wiring is done by connecting the Serial3 + terminal on the SCADAPack 575 to the A+ serial port terminal on the Vortex Meter. The Serial3 - terminal on the SCADAPack is wired to the B- terminal on the Vortex meter.
Inside RemoteConnect the Modbus Client needs to be configured. In order to configure the client the Modbus address of the Vortex meter is required. Often the Vortex meter is at Modbus station 99.
When configuring the Modbus server device verify setting against the target device. Device Address and Modbus Byte Order are items that can commonly vary between devices.
Within the Client configuration the registers of interest need to be identified. For this example registers 30501 - 30540 are being read back. These registers are Modbus Real (or floating point) values.
Add the Scanner
Configure the scanner to read the registers 30501 - 30540 by selecting a starting address of 30501, quantity of 40, and data type of REAL.
This register range corresponds to the following from the Vortex meter. Refer to current documentation for the meter your polling to confirm for the device being used.
After downloading the program to the SCADAPack 575 the register values should start updating.
