Some versions of VersaPro software allow configuration of RTU and Serial I/O at 115.2K
baud. However, this baud rate is not supported by the CPU. If a configuration using this
baud rate is stored to the PLC:
1. For RTU, an Unsupported Feature in Configuration fault is logged and the PLC
transitions to Stop Faulted mode.
2. For Serial I/O, the same fault is logged when the transition to Run mode occurs. The
PLC will immediately transition to Stop Faulted mode.
