Hello, Interesting question form UMENCHO, Why would you change the CPU with the same one?! Do you have any INTF, EXTF or BF? If you don't have any faultand you just need to have spare parts then buy the CPU with same order number and keep it in stock. Why would you shutdown the plant?! I suppose Siemens CS knows more however I can't find a technical reason for not confirming that newer CPUs will run without error. Take a look at these links. http://support.automation.siemens.com/WW/view/en/19913888 http://support.automation.siemens.com/WW/view/en/24641526 http://support.automation.siemens.com/WW/view/en/25208203 http://support.automation.siemens.com/WW/view/en/22919199 Best regards.

Hello, Successor product: If the only difference between the order numbers is the last digit of the middle block, then compatibility is ensured. CPU replaced by a successor CPU,it should work even if you not modify the H.W What should you watch out for when changing from one S7-400 CPU to another? |
