Digital input V1 / V2, V3 / V4 (plug-in module)
A digital input can be implemented via the 'Passive digital input
(yellow)' plug-in module.
Can be configured as an input for external counter reset,
external output deactivation etc. via on-site software.
Figure 41: Plug-in card as digital input (I = internal, E = external)
The plug-in module can be used in slot OC1 or OC2.
