Can i physically change 6ES7 214-1BG31-0XB0 to a BG40

Can i physically change 6ES7 214-1BG31-0XB0 to a BG40 without using TIA Portal (update HW and download into a BG40)?

Hello RomkaS;

Here is the information available in Product Support about the successor module for the 6ES7214-1BG31-0XB0 (see the attachment below).

The 6ES7214-1BG40-0XB0 is designated as the successor module for the 6ES7214-1BG31-0XB0. So far, so good.

A Siemens successor module normally should be able to replace an original part number, one for one, without even a requirement for change in the programming and configuration. But look at the note in German at the bottom of the entry (translated for your ease of use): the new module is "conditionally compatible" with the original. I have not been able to find information of these compatibility issues, except the size of memory on each and the mention of a firmware difference between the two.

In your shoes, I would personally go ahead with the replacement, and simply be aware that some warnings may appear during the changeover, and deal wit them as they come along.

However if you decide to be more prudent, I would suggest that you contact Siemens Support (through a Support Request, link at the top of this page) and inquire to Siemens techjs about the conditions for complete compatibility between the 2 modules.

Hope this helps,

Daniel Chartier

The release information for the S7-1200 CPUs with FW4.x says:

https://support.industry.siemens.com/cs/ww/en/view/86567043

Compatibility of the Hardware and Software

An S7-1200 CPU V4.0 is (spare-parts-) incompatible with an S7-1200 of Firmware V3.0.

An existing S7-1200 project, created for Firmware V3.0, can continue to be used on a CPU V4 after compiling the project (error-free) with the engineering system STEP 7 Basic / Professional from V13.

So the answer in your situation is: No, you need TIA Portal.

miami, dchartier, thanks you for help!

Hello,

some addition to guys info, I'll be careful if some communication via ETH is made, maybe via OUC or MB TCP, some serial connection because difference in libraries, sometimes I see it not compatible (3 vers. 4 firmw.) so pay attention to this if some kind of this solution is on old CPU. In this case I doubt about only replace, in my opinion you'll need reprogram these parts. Only my look to this situation. I'll be greatful to you post info after replace, what was problem and what you've done to succes...

Hello!

Hello,

thnx for info, little bit I've expected that (also with mentioned comm library). I don't have chance to do that tests so thnx for quick basic tests. If I'll have HW for tests also will do some...

Update: we have some problems with compatibility started in 2014 and logically differ prjs with differenet firmw. just a little info...
