Panel 800 with PM 554 Ac500-eCO PLC through Modbus RTU and to act as gate way througth the RS422 ModBusPanel 800
i will use the PP874 to be connected with the PM554 AC500-eCO through Modbus RTU (RS485) and to use the same panel to act as a gate way Between the PLC and the Control Technique DC drive through Modbus RTU (RS422)
is there any documents that can help to do such configuration
i understand that the PP874 shall be the master on the Bus ... is that correct ? how it will talk to the C.T drive?

The Panel 800 (both 5.1 and version 6) can act as a gateway between different protocols (drivers). 5.1 only between two but Version 6 for many (max three is recommended for the PP87x series).
Pls search for Panel 800 in ABB Library and the software is also free for in-house use.
Version 6 series:
It is possible to use multiple drivers with one operator panel. This means that the operator panel can communicate with different controllers simultaneously. The controllers can be connected to the serial ports on the operator panel and via the Ethernet port.

As for acting as a "gateway" - The PP800 is designed as an operator panel, not a gateway. Even if it can work as a gateway ( I have no idea, but I suspect it cannot), you would have to program the entire interface. I think perhaps you would be better to use a protocol converter which requires no programming at all... http://tinyurl.com/lgm3a4g
