For details, please refer to the following table to set up the communication
format for a serial communication port.
Communication timeout, unit: ms
Suppose the setting value is larger than 0. When the PLC executes the
communication instruction and is in the receiving state, but no data is received
SR183
after the timeout period or the intervening time between two characters exceeds
the setting value, the timeout flag is ON. You can set the register to 0 to disable
communication timeout monitoring. See the MODRW instruction set between
100–32767 (ms).
