Trouble Communicating through a Modicon/Schneider BM85 Modbus Bridge

Last Update: 11/7/2018

Users unable to connect to a device via the Modicon/Schneider BM85 gateway should first make sure that the BM85's port mapping table is set properly.

Note: If using the Modbus RTU Serial driver, it may be necessary to select DTR flow control. To do so, open the server's Channel Properties and then open the Communications tab. In Flow Control, select DTR.
