7.2.5 Setting Virtual Multi-Function Input
Multi-function input 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 operates independently
from In.65
–69 analog multi-function inputs and cannot be set redundantly. Virtual
multi-function input can be monitored using CM.86 (Virt Dl Status). Before you
configure the virtual multi-function inputs, set the DRV code according to the
command source.

Example : When sending an Fx command by controlling virtual multi-function 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.
