I'm trying to read a timer's present value off a iFix HMI. I'm connected through ModBus Ethernet to a Modicon Premium TSXP57.

Does anyone know the addressing range for the timer registers?

regards

 

We've used iFix with the Premium PLCs as well. My understanding is that the Modbus addresses only refer to the %M (discrete 0x bits) and the %MW (4x registers) within the Premium. I believe you'll have to do an internal data copy from the timer registers current value (%TMi.V) to a %MW register. Keep in mind that the value in that register will be in the same units as the timer is set up for (ms, sec, etc).
