2. Set the bus coupler address (see section 9.2 "Assigning a POWERLINK address" on page 98).
3. Enter a sub-object for each module of the valve unit that is mapped to the PDO:
– One Rx for each input module
– One Tx for each output module
– One Rx and one Tx for each combined input/output module
You can also enter parameters for each module. If more detailed mapping is preferred, instead
of using the universal XDD file, you can create an XDD file adapted to the unit. The CD R412018133,
included on delivery, as well as the AVENTICS Media Center, features an XDD Generator. It can be
used to create XDD files that are specifically adapted to the individual unit. To ensure proper function
of the XDD generator, Java must be installed on the computer.

Configuring the bus coupler in the fieldbus system

Before you can configure the individual components of the valve system, you need to assign
an address to the bus coupler.
1. To assign the bus coupler an address (see section 9.2 "Assigning a POWERLINK address"
on page 98).
– To assign an address with an address switch, see section 9.2.1 "Manual address assignment
with address switch" on page 98
– To assign an address with the "Browse and Config" tool, see section 9.2.2 "Address setting with
the "Browse and Config" tool" on page 99
2. Configure the bus coupler as a slave module with your PLC configuration software.

Module sequence

The input and output objects used by the module to communicate with the controller consist
of 4 bytes per module. The lengths of the valve system input and output data are calculated from
the number of modules multiplied by 4 bytes.
In the example (see Fig. 3), the modules are numbered to the right of the bus coupler
(AES-D-BC-PWL) 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).
Bridge cards are not taken into account. Supply boards and UA-OFF monitoring boards occupy one
module (see module 7 in Fig. 3). The supply boards and UA-OFF monitoring boards do not add any
bytes to the input and output data. However, they are also counted, since they have diagnostic data,
which is transferred at the corresponding module position. No object, neither Rx nor Tx, is created
for the electrical supply boards or UA-OFF monitoring boards, since no data is entered in the PDOs.
Pressure regulators and combination modules require one input and output data object each.
The numbering is continued in the I/O zone (module 10 to module 12 in Fig. 3). There, numbering
is continued starting from the bus coupler to the left end.
The parameter data is transferred via the device parameters on start-up. The bit assignments
of the bus coupler are described in "5.5 Setting the bus coupler parameters" on page 85.
The diagnostic data of the valve system is 8 bytes in length and is appended to the input data.
You must therefore enter two further input objects in the Rx list in addition to the connected input
modules. The structure of this diagnostic data is described in Table 14.
