7.7 Replace modules with the function "Change During Operation"
Requirements
You can replace the modules while operating the ET 200M if the ET 200M
• on the rail with active bus modules for the function "Module Change During Operation"
• and the ET 200M is configured for "Module Change During Operation".
WARNING
Inserting output modules can lead to uncontrolled system states!
This also applies if you insert input / output modules tilted on the bus module.
When inserting an output module, the outputs set by the user program become active
immediately!
We therefore advise you to set the outputs to "0" in the user program when removing the
output module.
If modules are not removed and inserted properly, neighboring modules via the
backplane bus can fail.
Removing a Module
When removing modules with "Module Change During Operation" proceed as follows:
1. Release the fixing screw(s) on the module.
2. Swing the module out.
3. Open the front door.
