Overheating in CP-E24/5.0 SORUCE and PM554 eth
As with all components, proper operation is subordinate to the right operating temperature.
If the temperature of the panel where you have the PLC increases excessively, you must provide air conditioning / recirculation to make the operating temperature correct.
All this can be avoided by using the AC500 XC series that can work up to 70 ° C but the eco series like PM 554 is not included in the AC500 XC category.
The presence of VSD in your electrical panel can disturb the analog signal of your AI 563, particulary if you not have correct do the shield connection to ground/earth.
Hope this help you
