How can I use the HMI keypad entry to trigger an action. Like, say an aperiodic Modbus write of some setpoints. Is there an equivalent to the SB30 in unilogic. I was hoping to use the generic "OK" button on the HMI numeric pad to write an array of values when any one of them is changed.

I have a Schneider M340. I am just new to Unilogic programming. The documentation seems to indicate that I can just setup the communication section with a remote slave under the Modbus Master section and add some operations to read addresses and it should work. Am I missing something. Do I need ladder code as well or can I just use the periodic reads in the communications section. BTHC_MU.ulpr
