5.5 Inserting and identifying the electronic modules
Features
• The electronic modules are inserted in the terminal modules.
• A labeling strip allows you to identify the electronic modules.
• Electronic modules are:
-- Self-coding
-- Type-coded
The first time you insert an electronic module, a code element engages on the
terminal module. This mechanically prevents the wrong electronic module from
being inserted.
Prerequisites
Adhere to the rules below for inserting electronic modules. See Section 3.5 (The
electronic modules you can use on the various terminal modules).
