12.2 Firmware update
Observe the following information when updating the firmware:
Requirements
The following conditions must be met so that you can carry out an update:
Connect the PC to an Ethernet connection X1 or X2 on the CIM.
Either an IP address must be assigned to the Central Interface Module (delivery state
0.0.0.0) or the CIM must be in operation on a PROFINET CPU (IP address from PROFINET
configuration).
Before the update, the connection to the CPU must be stopped or interrupted.
Note
If the connection is not interrupted, an error message appears in the PC tool, but this can be
delayed.
CIM:
The update encompasses two firmware parts and is not completed until both parts have
been successfully loaded.
After the update, the HCS4200 restarts automatically. Only in the event of a fault when the
update has not been correctly completed do you have to restart the HCS4200.
POM:
In the event of a firmware update, all Power Output Modules that are operated on a Central
Interface Module are loaded together with the new firmware.
After the update, the HCS4200 restarts automatically. Only in the event of a fault when the
update has not been correctly completed do you have to restart the HCS4200.
I/O module PM:
In the event of a firmware update, new firmware is loaded into the inserted PM. After the
update, the HCS4200 restarts automatically. You have to restart the HCS4200 only in the
event of an error when the update was not correctly ended.
