ReLab Protocol Server Bridge Manual

ReLab Protocol Server Bridge implements “Slave” capability of IEC 60870-5-101, IEC 60870-5-104, Modbus Serial and Modbus TCP/IP protocols with ability to turn your computer into Slave Device. The application developed for 32-bit industrial platforms and fully compatible with a TCP/IP stack and Serial interfaces. The application provides custom API with advanced features, which allow user to write into “read-only” registers. With the complements of ReLab Software Logic Controller (RLSLC) user can access OPC address space and perform protocol conversions. This manual explains required steps to configure these drivers.
