Variant C: Equal duty cycle during the week
A timing program triggers the switch between network nominal pressure
pA and network nominal
pressure
pB (local operating mode: pA/pB SC2Clk).
Precondition The network nominal pressure
pA/pB is configured the same for both machines.
➤ The timing program is set up using the following switching points:

8.12 Setting input and output signals
The controller's analogue and digital inputs and outputs can be used for customised messages
and/or other functions.
The various options are explained in the following chapters:
■ 8.12.1: Output operational states of machine on digital outputs
■ 8.12.2: Output input signals on the display
■ 8.12.3: Output measured values on the display
■ 8.12.4: Switching and/or triggering messages with thresholds
The controller only allows assignment of spare inputs and outputs.
Any assignment of a pre-assigned input or output is discarded by the controller.
When delivered from the factory, the outputs DO0.3 to DO0.5 are available for assignment.
Further spare outputs can be found in the machine circuit diagram.
➤ Set the inputs and outputs as described below.
8.12.1 Output operational states of machine on digital outputs
Important operational machine states can be made available as digital signals via floating contacts.
Each output can be assigned only once.
The following messages can be output:
