Changing the type of an I/O module
Introduction
The coding element is a two-part element. When shipped from the factory, both parts are in
the I/O module. When an I/O module is installed for the first time, a part of the coding
element clicks into the BaseUnit. This mechanically prevents the insertion of a different
module type.
There are two versions of the ET 200SP distributed I/O system:
● Mechanical coding element: Ensures the mechanical coding described above.
● Electronic coding element: In addition to the above-mentioned mechanical coding, this
version also has an electronic, rewritable memory for module-specific configuration data
(such as the F-destination address for fail-safe modules, parameter data for IO link
master).
