4.1.3 Address switch

Fig. 8: Location of address switches S1 and S2
Fig. 9: Rotary switches S1 and S2
The two rotary switches S1 and S2 for manual valve system IP address assign-
ment are located underneath the window (3).
• Switch S1: The higher nibble of the last block of the IP address is set at
switch S1. Switch S1 is labeled using the hexadecimal system from 0 to F.
• Switch S2: The lower nibble of the last block of the IP address is set on switch
S2. Switch S2 is labeled using the hexadecimal system from 0 to F.
For a comprehensive description of addressing, see section
the Bus Coupler.

4.2 Valve Driver

The valve drivers are described in section

5 PLC Configuration of the AV Valve System

For the bus coupler to exchange data from the modular valve system with the
PLC, the PLC must be able to detect the input and output data lengths of the
valve system. In order to represent the actual configuration of the valve system's

electrical components in the PLC, you can use the configuration software of the
PLC programming system. This process is known as PLC configuration.
You can use PLC configuration software from various manufacturers for the PLC
configuration. The descriptions in the following sections therefore focus on the
basic procedure for configuring the PLC.
Configuration error!
An incorrect valve system configuration can cause malfunctions in and dam-
age to the overall system.
1. The configuration may therefore only be carried out by qualified personnel,
see section
2. Observe the specifications of the system owner as well as any restrictions
resulting from the overall system.
3. Observe the documentation of your configuration program.
You can determine the system data length on your computer and
transfer it to the system on site without connecting the unit. The data
can then be loaded on the system at a later time on site.

5.1 Readying the PLC configuration keys

Because the electrical components in the valve zone are situated in the base plate
and cannot be identified directly, the PLC configuration keys for the valve zone
and the I/O zone are required to carry out the configuration.
S2
You also need the PLC configuration key when the configuration is carried out in a
different location than that of the valve system.
Note down the PLC configuration key for the individual components in the fol-

lowing order:
- Valve side: The PLC configuration key is printed on the name plate on the
right side of the valve system.
- I/O modules: The PLC configuration key is printed on the top of the modules.
A detailed description of the PLC configuration key can be found in
section g 12.4 PLC Configuration Key

5.2 Configuring the Bus Coupler in the Fieldbus System

Before you can configure the individual components of the valve system, you
need to assign an IP address to the bus coupler using your PLC configuration soft-
ware. In most cases, a DHCP server assigns the address during commissioning
and subsequently permanently assigns it to the device.
1. Assign the bus coupler a unique IP address using the configuration tool, see
sectiong 9.3 Assigning IP Address and Subnet
2. Configure the bus coupler as a slave module.

5.3 Configuring the Valve System

5.3.1 Module sequence

The input and output data used by the modules to communicate with the con-
troller consist of a 16 bit word string. The lengths of the valve system input and
output data are calculated from the number of modules and the data width of
the individual module. The data is only counted in words. If a module has less
than 1 word of input or output data, the left-over bits are "stuffed" to the word
boundary using non-information bits.
Example: A valve driver board, 2x, with 4 bits of payload data occupies 1 word in
the word string, since the remaining 12 bits are stuffed with non-information
bits. The data of the next module therefore starts after a word boundary.
The modules are numbered to the right of the bus coupler in the valve zone,
starting with the first valve driver board (module 1) and continuing to the last
valve driver board on the right end of the valve unit (module 9). See g Fig. 10.
Bridge cards are not taken into account. Supply boards and UA-OFF monitoring
boards occupy one module. See
OFF monitoring boards do not add any bytes to the input and output data. How-
ever, they are also counted, since they have diagnostic data, which is transferred
at the corresponding module position. The data length for pressure regulators
can be found in the operating instructions for AV-EP pressure regulators
(R414007537).
The numbering is continued in the I/O zone. There, numbering is continued start-
ing from the bus coupler to the left end.
