WRITE_INPUT_DINT is used to simulate (write) a value at a variable, IODDT variable, or state RAM. The input is written directly when WRITE_INPUT_DINT is invoked.
The function block can be used with a real PLC and the PLC simulator.
Restrictions
-
The function block provides access to one variable at a time (elementary data types and not arrays of elementary data types).
-
The simulation block WRITE_INPUT_DINT does not work if the I/O module is configured in a RIO drop but works properly if the I/O module is configured in a local rack or DIO device.
NOTE: Using the WRITE_INPUT_DINT EFB with RIO networks, the behavior in simulation mode could be different from PLC behavior. The input is set by the WRITE_INPUT_DINT EFB but overwritten by the value sent by the RIO scanner in the OUT phase of the PLC scan.
The additional parameters and can be configured.
