5.2.19 Remote Modbus DI State
ONLY AVAILABLE IF A MODBUS KEY FILE HAS BEEN IMPORTED AND THE COMM STATUS IN THE
REMOTE COMMUNICATIONS MENU HAS BEEN SET TO MODBUS
The Remote Modbus DI State input is used to simulate a switch closure by obtaining the open or closed state
information from a Modbus application via Modbus TCP. This information can be used to Interlock or activate a
control output in exactly the same way as a physical switch. This virtual input type however uses up an actual input
channel.
Input Details
The details for this type of input include the current state with a custom message for open versus closed, alarms,
the status of the interlock, date/time of the last update, cycle time, 24-hour time, total time, date/time of last total
time reset and the current type of input setting.
