Special register Function
D1038
Delay time of data response when PLC is SLAVE in COM2, COM3
RS-485 communication, Range: 0~10,000. (Unit: 0.1ms).
By using EASY PLC LINK in COM2, D1038 can be set to send next
communication data with delay. (unit: one scan cycle)
D1050~D1055
Converted data for Modbus communication data processing. PLC
automatically converts the ASCII data in D1070~D1085 into Hex data
and stores the 16-bit Hex data into D1050~D1055
Supported communication instructions: MODRD / RDST
