Relays, function relays
The logic relay has different types of relay for wiring in a
circuit diagram.
You can set the switching behaviour of these relays by
means of the coil functions and parameters selected.

In order to ensure compatibility with the AC010 devices,
each CL-LSR/CL-LST and CL-LMR/CL-LMT logically
supports all relay types internally. If a relay type is not
supported by the device, the switching state of the
contacts is always set to zero. The switching states of
contacts (n/o) and time switches are always logically zero.
This feature enables the same circuit diagram to be used
on all CL-AC1, CL-AC2, CL-DC1 and CL-DC2 devices.
Furthermore, you can use outputs that are not physically
present as markers.
