Hi Farhad-ALP, The 6ES7151-7AA21-0AB0 is the compatible follow-up type of the 6ES7151-7AA20-0AB0. If a CPU is replaced by a compatible follow-up type, the STEP 7 project does not have to be changed. It is also not necessary to update the STEP 7 software. However, this does not apply in the opposite direction. Unfortunately, your picture does not show the order number of the CPU currently used in your configuration. However, the picture shows that the CPU has firmware version V2.6. This would indicate that your configuration contains the 6ES7151-7AA20-0AB0, since this PLC has firmware version V2.6, while the new one will have version V3.3. If this is correct, you do not need to change your configuration because it is already correct. Kind regards |
