Port
Display of the internal designation for a digital input port of the type
DigIn_x_y_z, where x stands for the controller, y for the digital input ter-
minal and z for the input on this terminal.
Port description
Freely selectable designation for a digital input port. This designation is
used in the program to actuate the port.
Input 50 characters
Default value DigIn_x_y_z
The following characters must not be part of the
port description: \ , ', ., {, }, [, ].
Note
The first digital input is connected to the emergency switch on the
wet end. If the switch is pressed, all modules connected to the control-
ler are set to their default status and do not react to other control com-
mands. The first digital input should therefore be called Emer-
gency_Module.
If a controller is labeled ok in the device table, the status of the emer-
gency switch is monitored. In case of an activated switch all running
determinations are canceled and a corresponding message is displayed.
If the network cable is disconnected on a running controller, then in the
device table the device is labeled not ok.
