Driver: Plant SCADA SBUS Driver Version: 3.04.xx.xxx Check the Drivers tab on the Products page at the AVEVA Knowledge & Support Center for information about driver updates and new driver pack releases. |
The SBUS driver supports SERIAL communication with the SAIA PCD PLCs. The protocol can use three different transmission methods:
1) Parity changing method
2) Break mode transmission
3) Data mode transmission.
The transmission method is determined by the [SBUS]SendBreak parameter. Refer to SBUS Driver Parameters for information on how to set the transmission method.
The maximum request length for the SBUS protocol is 16 bits.
Citect SCADA 7.20 or later (or a later version of Plant SCADA) is required to use the SBUS Driver.
Hints and Tips
To setup the proper communication modes for SBUS with PCDs, you may need to use the utilities provided by SAIA to alter the firmware settings of the PCD devices. Refer to the topic titled Software Setup for software and firmware version required for SBUS Data Mode.
