Setting Virtual Multi-function (digital) Input
Multi-function (digital) inputs can be controlled using a communication address (0h0385). Set
codes CM.70 ~ 77 to the functions to operate, and then set the BIT relevant to the function to 1 at
0h0322 to operate it. Virtual multi-function (digital) inputs operate independently from In.65–69
digital multi-function (digital) inputs and cannot be set redundantly. Virtual multi-function (digital)
inputs can be monitored using CM.86 (Virt Dl Status). Before you configure the virtual multi-
function (digital) inputs, set the DRV code according to the command source.

Example: When sending an Fx command by controlling virtual multi-function (digital) input in the
common area via Int485, set CM.70 to FX. Then, assign a 0h0001 value to the communication
address 0h0322 to operate the forward direction operation (Fx) feature.
NOTE: The following are values and functions that are applied to address 0h0322:
