Sequence of addressing Description
1. Status bits or I/O
diagnostic interface
1)
Delivers status and diagnostic information; activate through DIL
switches; occu pi e s the first 16 inpu ts or inpu ts and outputs
2)
2. Analogue modules Modules with analogue inputs/outputs
3. Technology modules e.g. CP interface, front end controller (CPX−FEC)
4. Digital modules Modules with digital inputs/outputs
1)
See also note above as well as Tab.1/2 and Tab.2/1.
2)
Depending on the setting, you can also occupy this address space with modules
(see also following information).
Tab.2/8: Sequence of addressing
If the status bits or I/O diagnostic interface are activated
later, that is, after the initial start−up, the module
configuration for the first 16 inputs or 16 inputs and outputs
must be adjusted.
Move the modules originally configured in this address
space into another area. Configuration of these modules
must be
repeated, if necessary (see also section 2.4
regarding configuration with EtherCAT configuration and
program software, e.g. Beckhoff TwinCAT).
Configuration examples
Example 1: CPX terminal with MPA1 and MPA2 pneumatic
Fig.2/1 shows as an example a CPX terminal with MPA
pneumatics and the following setting:
 Status bits and I/O diagnostic interface deactivated
The address assignment for this example terminal
(inFig.2/1) is shown in Tab.2/9.
