Description
In this menu, the digital inputs of the CU 351 can be set. Each
input, except DI1, can be activated and related to a certain
function.
As standard, the Control MPC has three digital inputs. If the

number of digital inputs is 12.
In the display, all digital inputs are shown so that their physical
position in the Control MPC can be identified.
