Some versions of VersaPro software allow configuration of RTU and Serial I/O at
115.2K baud for CPU005. 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.
2.5 Mode Switch
The CPU module has a convenient switch that can be used to place the PLC in Stop or
Run mode. The same switch can also be used to block accidental writing to CPU memory
and forcing or overriding discrete data. Use of this feature is configurable.
The default configuration enables Run/Stop mode selection and disables memory
protection.
