Can someone help me understand a little bit better MSTP slave devices? I understand they do not particpate in the passing of the token and therefore cannot initiate information requests, only respond to masters request for info from them. From what I gather most are also only 1/8 load transceivers so you can add more than normal on the bus.
What I am looking for is:
1) What other devices on the network do you need to communicate to them - I have seen some references to a Master proxy - what is that?
2) How many devices can you realistically put on one trunk - the max number of masters is 124 but slave devices can exceed that?
3) What is the impact on polling rates/baud rates/performance, etc. when adding slave devices to a MSTP trunk.
4) Is anyone using them extensively? Most of the bacnet devices I come across are masters on the MSTP network.
