1761-net-aic

Hi Folks:
I'm trying to make connection with a 1761-net-aic module , 2 PLC, 1 PC..
I've connected a plc 1747-L532 (SLC500, 5/03) to port rs-485, I'm
using cable 1761-CBL-AS03 between plc and net-aic converter, also
I've connected a plc ML1000 to port rs 232(8 pin MINI DIN),using
cable 1761-CBL-AM00, between net-aic converter and PLc.
And from 1761-NET-AIC to PC. I'm using cable 1747-CP3, port (DB9,DTE).
I've configured in RSlinx driver 1747-PIC/AIC+driver:
For: ML1000 is AB_PIC.
For: SLC 500 5/03 is AB_PIC.

I can see only one PLC (SLC 500 5/03.)
What's wrong ?
Please help me Guys.

Baud rates the same on all devices?

Different node address?

A ML1000 series D or greater will sense the protocol automatically, what series do you have. If not "D" then is the port configured for DH485?

Thanks for your fast reply Mickey:
My PLC ML1000 is a 1761-L16BWA, serie E, FRN1.0

The settings of ML1000 -Primary Protocol DH485.
-19200 BAUD.
-NODE ADDRESS 1

The settings of SLC500 -CH1 SYST. DH485. 5/03 CPU.

The node addresses need to be different.

e.g. ML1000 "1", SLC5/03 "2", PC "0"
