I have an SLC 5/03 installed on plant that i want to interface via DH485 link to our TDC3000 DCS. The distance is about 180 m so we're going to use RS485 signal levels.
It was first proposed the use of an ALLEN-BRADLEY SI FTA EIA-232 INTERFACE but later i checked the manual and it specifies communications support for the Allen-Bradley PLC-2, PLC-3,and PLC-5 devices only.
I was wondering if someone out there have tried to interface to an SLC/03 succesfully. If so, which additional hardware (if necessary) and software do i need to configure the complete communication system, including the TDC3000. If not, how can it be done?
I checked an 1770 KF3 was required for bridgeing between DH485 SLC 5/03 port and the RS232 FTA port. I think that is not necessary considering that both the FTA and SLC 5/03 talk DF1 protocol. I would only need a regular RS232/RS485 converter to go 180m through the link. What do you guys think?
thanks a lot in advance.
