3.2 PLC communication protocol
PLC communication protocol is selected when P.33 is set to 2, P.48~P.50 set the communication format,
P.32 selects the communication baud rate. PLC protocol is a special protocol for PLC program download
and communication between embedded PLC and Shihlin HMI. Currently Shihlin HMI EC200 series
supports this protocol.
It can be used with HMI to realize I/O monitoring, internal soft device monitoring and PLC program
operation monitoring.
