Functional earth connection
8
Fig. 5: FE connection
To discharge the EMC interferences, connect the FE connection (8) on the bus
u
coupler via a low-impedance line to functional earth.
The line cross-section must be selected according to the application.

4.1.2 LED

The bus coupler has 6 LEDs.
The following table describes the functions of the LEDs. For a comprehensive de-
scription of the LEDs, see g 11. LED Diagnosis on the Bus

4.1.3 Address switch

Fig. 6: Location of address switches S1 and S2
The two rotary switches S1 and S2 for manual valve system address assignment
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
Coupler.

4.2 Valve Driver

The valve drivers are described in

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 number of input and output modules. A
sub-object is mapped to the input or output PDO for each valve system module.
This process is known as PLC configuration. Each of these sub-objects has a data
volume of 4 bytes. Only the bits that have functions in the module are used, e.g.
of these 4 bytes, a 2x valve driver uses only the 4 least significant bits, a 16x input
module uses only the 16 least significant bits, etc.
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.
You may require the "Browse and Config" tool to be able to address the bus cou-
pler.
INFO: The "Browse and Config" tool can only be used on Gen.1 bus couplers to
activate address assignment.
The CD R412018133, included on delivery, contains the "Browse and Config"
tool.
