12.6 Conversion of the I/O zone

12.6.1

Permissible configurations

No more than ten I/O modules may be connected to the bus coupler.
For further information on converting the I/O zone, see the system descriptions of the individual
I/O modules.
We recommend an expansion of the I/O modules starting from the left end of the valve system.
12.6.2

Conversion documentation

The PLC configuration key is printed on the top of the I/O modules.
Always document all changes to your configuration.

12.7 New PLC configuration for the valve system

Configuration error!
An incorrect valve system configuration can cause malfunctions in and damage to the overall
system.
The configuration may therefore only be carried out by an electrical specialist!
Observe the specifications of the system owner as well as any restrictions resulting from
the overall system.
Observe the documentation of your configuration program.
After converting the valve system, you need to configure the newly added components.
In the PLC configuration software, adapt the lengths of the input and output data to the valve
system.
Because the data is transferred as a byte string and divided up by the user, the position of the data
in the byte string will shift if an additional module is used. However, if you add a module at the left
end of the I/O modules, with an output module, only the parameter byte for the bus coupler will
be shifted. With an input module, only the diagnostic data will be shifted.
After converting the valve system, always make sure the input and output bytes are still correctly
assigned.
If you have exchanged components without changing their order, you do not need to reconfigure
the valve system. All components will be recognized by the controller.
For the PLC configuration, proceed as described in section 5 "PLC Configuration of the Valve
System" on page 85.
