General information on maintenance and servicing
Observe the following when servicing and repairing protective equipment e.g. such as
ground circuits or overvoltage protection components:
● Observe the maintenance and replacement intervals.
● Replace system components, including external cables, fuses and batteries only with
equivalent components approved by the respective manufacturer.
Replacing the Mobile Panel
When replacing an HMI device, the following applies:
● A fail-safe Mobile Panel may only be replaced by another fail-safe Mobile Panel.
● For a 1:1 data transfer from one HMI device to another, a replacement device with
identical construction is required.
● If you do not use an identical replacement device, you have to adapt the configuration
and transfer the adapted project to the replacement device. During adaptation of the
project, observe the following:
– The display size of the HMI devices
– The number of used direct keys
– The evaluation of the keyswitch
– The use of the "automatic backup" function
– The information on switching devices in the WinCC information system
Below you will find a description of how to replace an HMI device with a replacement device
with identical construction.
Replacement device with identical construction, manual backup exits
1. Insert the storage medium with the manually created backup into the slot of a
replacement device with identical construction.
2. Proceed as described in the section
"Restoring from external storage medium – Restore (Page 147)".
