I'm working with a Micrologix 1500 (1764-28BXB)on a machine and I was trying to get it to talk to a panelview 300 micro (2711-M3A19L1) directly (via 1761-CBL-HM02). After discovering the 1500 was configured for DF1 and wouldn't talk to the panelview, I managed to change the communication to DH485 within rslogix500 and download this change into the PLC. After doing this all was happy in the world and I got the 612 network node error to go away on the screen and the panelview working just fine; reading my I/Os perfectly. As soon as main power was cycled (power off then back on) to the 1500 and panelview the communication link was lost and the 612 network node error showed up again. I don't know what could be causing this. I haven't looked yet, but I suspect it reverted back to the DF1 protocol again. Why? What am I doing wrong? I haven't worked with 1500s very much. I'm used to working with the SLCs and I've never had this problem before.
