Digital inputs
The operating panel offers a 20-pole plug bar block e.g. for connection of 16
external toggle switches.
Information
These digital inputs are not EN 61131-2 conforming and may not be utilized
for machine/system functions that require the EN EN 61131-2 conforming
digital inputs. For such cases, use the conforming digital inputs of the control.
Information
For the selection of the switching elements, the
specifications in section "Digital inputs" are to be taken into
account.
