Attention:
In the system CECX the access of direct adressed BOOL-variables (%IX0.0, %QX0.0, %MX0.0) is not
possible. The access to bits must be always byte wise.
Address setting for modules
Die station address is set on the module via rotary switches (hexswitch).
The following rules apply for assigning addresses:
ï‚· Modules of the same type (e.g. several CECX-D-16E modules), that have been added to the
same CPU module, must have different addresses.
If this instruction is not adhered to and address conflicts result, it is possible that
modules are not recognized and that inputs/output settings are duplicated, set
incorrectly or not set at all.
ï‚· Different type modules (e.g. a CECX-D-16E module and a CECX-A-4E4A-V module on a CPU
module) can use the same address settings.
In the CoDeSys configuration there are two options for specifying addresses:
1. Auto
2. Pre-defined value between 0 and F (Hex).
The "auto" setting is intended for those instances where the control does not contain several modules of
the same type. Here it is not necessary to inform the programming system of a fixed, pre-defined address.
A pre-defined value must be specified when several modules of the same type are used in the control and
the modules must be differentiated. The "address" module parameter specified in the configuration entry
must then agree with the switch position set on the module.
