Replaceability of Power Panels:
Starting with the specified versions, Power Panel C70 variants with the same characteristics can be replaced
without having to change the Automation Studio project:
•
Quantity and type of interfaces
•
Panel size
•
Display orientation
That means Power Panel C70 variants are interchangeable if the only difference between them is the color
(panel overlay).
A Power Panel C70 can therefore be replaced with a different panel overlay variant (or customized panel over-
lay) without having to make any changes to the Automation Studio project.

3.2.2 Temperature monitoring
Automatic overtemperature shutdown
To prevent damage to the device, the inner temperature of the device is monitored continuously. If the internal
temperature of the Power Panel reaches or exceeds 88°C, an automatic shutdown occurs (reset state).
The following errors are entered in the logbook in the event of cutoff:
Error number
Short error text
9204
PLC restart triggered by the PLC CPU's temperature monitoring.
9210
Warning: Halt/Service after watchdog or manual reset.
Monitoring by the application
The application can additionally monitor the temperature and, if necessary, take appropriate corrective measures
before the automatic cutoff occurs.
Two data points are available for this purpose:
Data point
Description
TemperatureCPU
Temperature of the CPU housing
TemperatureENV
Inner temperature of the Power Panel
Important!
In worst case operation, the temperature of the CPU housing can achieve temperatures over 100°C.
Use case
Under certain circumstances (e.g. specified distances to ventilation cannot be observed, see
), it makes sense for the application to monitor the Power Panel temperature. The application
can take appropriate corrective measures if a certain temperature is exceeded.
