Does anyone have the schematic for building a com cable to connect a Panelmate Power Pro 1775T to a Ge Fanuc 90-30 plc? I know I can purchase one, but this is for a pet project so I'm trying to keep costs down. Thanks.
Be sure to specify RS485 (or is it RS422?) in the PanelMate port setup.
I've run into two issues regarding communications between PanelMates and GE Fanuc 90-30s. First, the PanelMate SNP protocol driver's default parity setting is "None", while the PLC's default setting is "Odd".
Second, older versions of the PanelMate SNP driver required a value to be entered for the SNP ID. In the PLC, the SNP ID defaults to a null value. Newer versions of the driver fixed this, and I'm not sure at which version it happened. If you encounter this problem, you will need to enter a non-blank value in the PLC's CPU configuration. Note that a value of zero is not the same as no value. I hope that by bringing up the second issue I haven't totally confused things.
