Hello,

I wanna send some simple data from 1 to for now second PLC, and later will add more PLC's to them

I am new into the TSEND etc, and have attached a simple start with 2 x 1214C first one is a 40  the second 31.

I have this working with a PUT instruction, but what am I missing here??

Thanks!

Jeroen

Hi,

I have seen several things:

TRCV_C should be enabled with "true" and not with 10Hz clock...

Did you check the Error and Status outputs ? If Error ist true, then save Status.

I am not sure but you only send one bit?!

First check Status, then we will find out your problem.

Please check this FAQ:

How do you program the TSEND_C and TRCV_C instructions for open user communication over the integrated PROFINET interface of the S7-1200 CPU?

Thanks!

That 1 bit was to try, i am pointing now to a DB   (P#DB10.DBX.0.0 BYTE 2)

I've changed TRCV  EN-R to 1 (true).

Status is: 16#8088

I have changed LEN to 0 and now it is working!!!

Thanks!!

Jeroen
