As due to continuous up-gradation of technology, MLFB of the CPU gets Changed day by day. For an Example CPU314. Latest MLFB is 6ES7314 1AG14 0AB0 V3.0. In one of my last Project, i used CPU314 was having MLFB 6ES7314 1AG13 0AB0. Now Customer wants a Spare CPU314 with 6ES7314 1AG13 0AB0. Now as CPU314C with this MLFB 6ES7314 1AG13 0AB0 is not available i will recommand him to take latest one. But in case if old CPU Fails then this new CPU will be Plug & Play? (by plugging MMC Card) or i have to replace part no in hardware Configuration and have to downlaod hardware? Thanks in advance.

In this case, 6ES7314 1AG13 0AB0 vs. 6ES7314 1AG14 0AB0 there is no problem to change without HW-download.

In the case of a spare part replacement: If you replace a CPU (e.g. 6ES7314-1AG13-0AB0) against a compatible follow-up type (in this case ES7314-1AG14-0AB0) the STEP 7 project need not be changed. It is also not necessary to upgrade the STEP 7 software version. best regards, Hristo Mihalev

When you use compatible follow-up types you can always work in the STEP 7 project with the order no. of the predecessor types.

Configuration with older software versions:
If the new functions are not required, the new module can be configured in STEP 7 as the predecessor with the latter's scope of functions. The larger work memory is nevertheless available.

In Hardware Config	Actual Hardware
6ES7314-1AG13-0AB0	6ES7314-1AG14-0AB0

It is also not necessary to upgrade the STEP 7 software version in this case.
