Hi, I'm facing some hardware selection problem for S7.
I have a Honeywell system that will communicate with my S7-315-2 PN/DP.
S7 will have 10 profibus slaves on 1 DP network and will be a DP slave for Honeywell using S8 profibus gateway module.
As S7 cannot be master and slave at the same time, i have to select a CP, and there is a problem:
CP-342-5 can send/receive max 240 Bytes in slave mode and I need a little more (circ. 300-360).
I was thinking about DP/DP coupler - but again it can only handle 240 bytes.
What do I need on S7 side to send more ( and I cannot multiplex send data ) ?
Here's the Honeywell PGM:
