• The analog input module 2AI2M12 has 2 inputs with a resolution of 16bits
each.
• 16 bits/8 = 2 bytes
• 2 bytes x 2 inputs = 4bytes input data
12.5 Conversion of the Valve Zone
The symbols for the valve zone components are explained in sec-
tiong12.2.Valve Zone.
NOTICE
Impermissible, non-compliant expansion!
Any expansions or reductions not described in these instructions interfere with
the basic configuration settings. This will prevent a reliable system configura-
tion.
1. Observe the rules for the expansion of the valve zone.
2. Observe the specifications of the system owner as well as any restrictions
resulting from the overall system.
You may use the following components for the expansion or conversion of the
system:
• Valve driver with base plates
• Pressure regulators with base plates
• Pneumatic supply plates with bridge card
• Electrical supply plates with supply board
• Pneumatic supply plates with UA-OFF monitoring board
With valve drivers, combinations of several of the following components are pos-
sible (see Fig.16):
• Valve driver, 4x, with two base plates, 2x
• Valve driver, 3x, with one base plate, 3x
• Valve driver, 2x, with one base plate, 2x
If you would like to operate the valve system as a stand-alone system,
a special right end plate is required (see ).
12.5.1 Sections
The valve zone of a valve system can consist of multiple sections. A section al-
ways starts with a supply plate that marks the beginning of a new pressure or
voltage zone.
An UA-OFF monitoring board should only be installed after an electri-
cal supply plate, otherwise the actuator voltage UA is monitored be-
fore supply.

The valve system in Fig.16 consists of three sections:
Table26: Example valve system, consisting of three sections
Section Components
Section1 • Pneumatic supply plate (30)
• Three base plates, 2x (20), and one base plate, 3x (21)
• Valve driver boards, 4x (24), 2x(22), and 3x (23)
• 9 valves (61)
Section2 • Pneumatic supply plate (30)
• Four base plates, 2x (20)
• Two valve driver boards, 4x (24)
• 8 valves (61)
• AV-EP base plate, single pressure control
• AV-EP pressure regulator
Section3 • Electrical supply plate (35)
• Two base plates, 2x (20), and one base plate, 3x (21)
• Supply plate (38), valve driver board, 4x (24), and valve driver board,
3x (23)
• 7 valves (61)
12.5.2 Permissible configurations
Fig.18: Permissible configurations
You can expand the valve system at all points designated with an arrow:
• After a pneumatic supply plate (A)
• After a valve driver board (B)
• At the end of a section (C)
• At the end of the valve system (D)
To simplify your documentation and configuration, we recommend
that you expand the valve system on the right end (D).
12.5.3 Impermissible configurations
Fig.19 displays the configurations that are not permissible. You may not:
• Split a 4x or 3x valve driver board
• Mount more than 64 valves (128 solenoid coils)
• Integrate more than 8AV-EPs
• Integrate more than 32 electrical components.
Some configured components have multiple functions and therefore count as
multiple electrical components.
