Hello all,

I need to make a communication via Industrial Ethernet by using CPU315-2PN/DP and CP443-1.
I have using BSEND and BRECV block for programming.
Program in CPU315-2PN/DP working properly, But program in CPU414-4H doesn't work.
It show error 1 and status 1.

Is it posible to configure like this ?
If no, how to let it work?

Hello

Status "1" and Error "1" means:

Communications problems, for example:

- Connection description not loaded (local or remote)

- Connection interrupted (for example: cable, CPU off, CP in STOP mode)

- Connection to partner not yet established

- FB cannot be run on an S7-400-CPU

I suggest you to check again your settings. Look at What should you watch out for when configuring an unspecified S7 connection for data communication between an S7-300 and an S7-400?

regards

Hello,

Thank you UMENCHO and J_Bell.
I was check the connection stateof block calls FBs BSEND and BRCV.
The connection state of S7-Connection within NetPro there are established.

I have using FBs in both of S7-300 and S7-400. I did't know S7-400 supports only SFBs.
I will try to use SFBs in S7-400.

Best regards,
