● In the delivery state a coding element is located in the module. When the front connector
is first inserted into the I/O module, a part of the coding element clips onto the front
connector. If the front connector is removed from the I/O module, one half of the coding
element remains in the front connector, and the other part of the coding element remains
in the I/O module. The insertion of a front connector that is not suited to the module is
thereby mechanically prevented. This ensures, for example, that the front connector with
the coding element of a digital module cannot be inserted into an analog module.
Further information about the coding element is also available in the chapterCoding
element at the I/O module
and at the front connector (Page 116
).
Reference
Further information on the use of the potential bridges can be found in the manual for the
respective I/O module.
