S7 1200 + WINCC OA Unsolicited communication

Post by davidpnacek »

Hi There,

I am wondering, is it possible to use PLC S7 1200 in unsolicited mode? In the wincc oa help I found info about BSEND function, which has to be used in order to send data from the PLC, but it seems to me, that the BSEND function is available only for s7 300/400/1500?
Is that right or am i doing something wrong?

If I click on S7 communication functions in TIA portal, I can see only functions PUT and GET. Also all examples across the internet show only S7 1500/300/400 devices...

Is there any other way how to use the s7 1200 without pooling mode?

Thank you

Receiving unsolicited data from an S7-1200 is possible in WinCC OA.
Which option you have to choose depends on the WinCC OA version and the driver you are using in WinCC OA, S7 or S7+ driver.
Detailed information for the drivers you can find in the WinCC OA Documentation.
