The modules are available in 2 versions. The SST-SR4-CLX-RLL module offers 4 independent RS232/RS485 serial ports operating as master and/or slave Modbus protocols supporting ASCII and RTU formats.

The SST-ESR2-CLX-RLL module provides 2 serial ports and 1 Ethernet port executing Modbus TCP (UDP and IP) protocol in both client and server modes simultaneously. The configuration set-up to exchange data is accomplished through a Windows software console that supports the Allen-Bradley Remote Link Library (RLL) feature, allowing remote monitoring and downloading of changes to the network configuration.
