12.4 PLC Configuration Key

12.4.1 PLC configuration key for the valve zone

Fig. 21: PLC configuration key on right end plate
The PLC configuration key for the valve zone (59) is printed on the right end
plate.
The PLC configuration key specifies the sequence and type of electrical compo-
nents based on a numerical/alphabetical code. The PLC configuration key con-
sists solely of numbers, letters, and dashes. There are no spaces between the val-
ues.
In general:
• Numbers and letters refer to the electrical components.
• Each digit corresponds to one valve driver board. The number's value refers to
the number of valve positions for a valve driver board.
• Letters refer to special modules that are relevant to the PLC configuration.
• "–" visualizes a pneumatic supply plate without UA-OFF monitoring board;
not relevant to the PLC configuration
The sequence begins on the right side of the bus coupler and ends at the right
end of the valve system.
The elements that can be represented in a PLC configuration key are shown in the
following table.

Example of a PLC configuration key: 423–4M4U43.
The transition plate and the pneumatic supply plate at the start of the
valve system, as well as the right end plate, are not included in the PLC
configuration key.

12.4.2 PLC configuration key for the I/O zone

60
The PLC configuration key for the I/O zone (60) is module-related. It is printed on
the top of the device.

The sequence of I/O modules starts on the left side of the bus coupler and ends
on the left end of the I/O zone.
The PLC configuration key encodes the following data:
• Number of channels
• Function
• Electrical Connection Type

Example:
The I/O zone consists of three different modules with the following PLC configu-
ration keys:

8DI8M8 • 8x digital input channels
• 8x M8 connections

2AO2AI2M12A • 2x analog output chan-
nels
• 2x analog input channels
• 2x M12 connections
• Additional actuator volt-
age connection
The left end plate is not reflected in the PLC configuration key.
Each module with inputs has an input object with a length of 4 bytes of which var-
ious numbers of bits/bytes can be used.
Each module with outputs has an output object with a length of 4 bytes of which
various numbers of bits/bytes can be used.
If a module has both inputs and outputs, then it has one input object and one
output object.
