PM554ETH Firmware update problem!
Upgraded the firmware of an PM554ETH from 2.x to 2.4.4, because after building the project with Automation Builder 1.1 the onboard IO's were not working and the PLC displayed an error. Automation Builder lists the AC500-eco firmware as 2.4.1 but no such download could be found. So I got the 2.4.4 version.
But after upgrading the AC500-eco to firmware 2.4.4 the PLC is stoned - no login is possible - neither Ethernet nor COM1!
The IP-configuration tool from Automation Builder "sees" the PLC with correct IP parameters.
Is there a way out, can I downgrade to the old version or shall I order a new PLC?
Thnx in advance!
one older version of FW is possible to download to cpu.
Search on abb library the file 1SAP190800R0233....this is the update from version 2.x to 2_3_3.
Check if the cpu with this FW version is correct recognized by sw on pc.
Next you can try to update from 2_3_3 to 2_4_4
You need to have SD card and SD card slot to insert in your cpu, because I think that without connection PC-PLC, it is not possible to perform by Automation Builder.
The SD card would be write of course by your pc, follow the PDF instruction inside the update ZIP file
Hope this help you, let us know about the results
