Hello, I FX3GA
to ask whether the type PLC
FX3GA with two communication modules, such as a FX3G-485BD, a FX3U-232ADP-MB, and FX3G-485-BD and FX3GU-485ADP-MB\FX3G-232-BD and FX3GU-232ADP-MB differences in use, thank yoult;img src=gt;
FX3GA mod take or take 60 points, you can extend the 2 communication adapter.Communication adapter cannot connect directly or through FX3G-CNV-ADPconnections, such as extended 2 RS-485 communication interface, configurationis as follows: FX3G-CNV-ADP+2*FX3U
-485ADP-MB. FX3U-485ADP-MB more than FX3U-485-BD MODBUS communication. Farthest distance difference: FX3U-485ADP-MB the communication distance of 500 meters, FX3U-485-BD most distant communication within a distance of 50 meters. FX3U-485-BD can be connected directly, and FX3U-485ADP-MB through FX3G-CNV-ADP to connect. FX3U-232ADP-MB more than FX3U-232-BD MODBUS communication. But the communication distance is 15 m. FX3U-232-BD can be connected directly, FX3U-232ADP-MB need to FX3G-CNV-ADP connection.
