Hi,

For my redondant comunication, I use FB909 MB_REDCL in V2.4. The following block are present in my PLC:

• FB908 MB_CPCLI (V2.3);
• FC50 AG_LSEND (V3.1);
• FC60 AG_LRECV (V3.1).

Only the FB909 is called into the "CFC CHART".

When I would like to download my projet, I have a compilation fault, FC50 and FC60 are not compatible with FB909 and FB908 without Hex#.

I try to remove FB909, FB908, FC50 and FC60 and download no problem.

My CPU is 416-5H.

Do you have an idea ?

Thanks.

You have to use rewiring.
