Hello hsnaik; Generally when any module presents all LEDs blinking status, it is a very bad sign. our first reaction is that there is a memory fault in the module, that would require repair or replacement. However, when searching in Product Support for your CP module (6GK7443-1EX20-0XE0) there appears a suggestion for a firmware update. There is no description of your specific fault in the firmware download page, but Siemens always recommends that older modules (your CP was placed in cancellation status in 2015) be raised to the latest firmware revision to correct known problems.Please check out these documents, and see if the CPU version is included in the firmware installation guidelines: Download for firmware update V2.4.1 of the CP 443-1 (6GK7443-1EX20-0XE0) https://support.industry.siemens.com/cs/ww/en/view/109480934 How do you download the firmware to Industrial Ethernet S7-300 CPs and S7-400 CPs using the firmware loader? https://support.industry.siemens.com/cs/ww/en/view/12213669 Note that if your CPU is part of a redundant S7-400H system, then all redundant modules on the rack should have the same firmware version, so if you decide tu update one, you must update the second CP 443-1 to the same firmware version. If this dis not possible or does not remove the error, the you should consider the CP 443-1 as defective. Hope this helps, Daniel Chartier |
