Master MODBUS RTU PLC CS1, CJ1 and CQM1 (H) (ladder)

Modified on Mon, 6 Oct, 2025 at 9:19 AM

Modbus Master for CJ1, CS1 and CQM1 had been amended to correct this problem with reset of the DM.

Attached is a Modbus program for CS1 and CJ1. The routine uses the same channels as the C200H-alpha bit version.
The attached documentation is the same as for the existing versions. (file SYSMOD.DOC)
