Modbus help
Posted: 17/12/2025, 8:23
I am trying to control a TCT101-4ABC-T in timer mode over Modbus. I've been successful with it however I seem to have issue with resuming the timer after issuing a pause (wait) command.
If I pause the timer by issuing a wait command (register 530, bit 6) then timer pauses (waits). But then if I issue the same command to have the timer resume, it won't resume it is stuck in wait mode. The only way I can get it to resume is by issuing a start command (address 530, bit 1) first followed by a bit 6 command. Is this normal behavior?
