There's a Micrologix 1400 PLC that needs to be connected to PV550 (not purchased yet). Micrologix 1400 Ch0 has an isolated DH485 on RS485. PV550 has an option of using isolated DH485 on RS485 as well (2711-T6C2L1). And, of course, both will need to be programmed, and perhaps monitored as an option. Micrologix 1400 manual (pg. 83) suggests using a Typical 3-Node Network, which is non-expendable.
My questions are:
1)Can Ch0 of the PLC be directly connected to the PV550 (2711-T5A2L1, without AIC+) and to PC through AIC+, creating RS485 network, which can be further expendable?
2)Can Ch2 of the PLC be configured for a Pass-Through to Ch0, for PC to program all devices on the network through Ch2, as it is in DH+ in SLC5/04?

Thank you

ok i;ll bite why not just use the ethernet port?
and why not look at other hmi options?
Havent used the red lion yet but from what i have seen on this fourm I think i will try one in the near future.
I find panelview to be getting lower and lower on my list. I use a lot of ml 1100 and 1400 ( I keep 6 in stock for those small projects that just seem to pop up) and use the
c-more op via e-net all the time. but IM not stuck on one brand unless my client specs it.

ok, PanelView was chosen, since the rest of the plant uses them, and it's more convinient for the staff.

Ethernet, is a good option, but I find rs485 be more robust to EMI, and because of its simplicity it doesn't have errors like - lost IP-address.
