(AS-H)-AS Communication PCS7

Hi All,

I've been trying to send data from a 417-4 H (running on library 6.1) to 414-3(running on library 8.1).

but with no success blocks that I'm using are Snd_AnaV and Rcv_AnaV, netpro was configured as active connection from the H PLC side, ID are entered correctly.

Version of PCS7 8.1

Send block have ID 5 

Receive block have ID 1

All seems correct but still not getting any data across do I need to use different type of blocks on the H mode PLC ? 

Thanks for help in advance. 

Hi Boost34,

if you communicate between S7-400H (redundant) and S7-400 (single) you have to use the blocks "SndH_DigVal, SndH_AnaVal, RcvH_DigVal, RcvH_AnaVal" from the Industry Library.

More information about the blocks you can find in the manual "SIMATIC Process Control System PCS 7 Industry Library for PCS 7 V9.0" in the section "Communication between S7-41xH and S7-41x"

with regards
