Reading Slave station diagnostics
The MEMORY AREA READ (0101) FINS command can be used to
obtain the last received Slave Diagnostics message.
Reading and controlling the error log
The internal error log records the history of error events. The Unit
supports the following Error Log related FINS commands:
• ERROR LOG READ
• ERROR LOG CLEAR
Station state changes
Allocated Slave stations can be disabled and enabled in order to
