CrosStar MT-200B W1300 Master Modem
The MT-200B W1300 Master Modem is a external Aquatrol W1300 Master station modem that communicates to all existing W1300 RTU's. Connects to any computer using RS-232C, the MT-200B looks like a Allen-Bradley PLC-5 talking DF-1 (Data Highway). This allows you to add or replace a central computer with ANY desired SCADA/MMI software package WITHOUT a special driver. The CrosStarMT-200B provides complete asynchronous polling of the W1300 remotes and DF-1 communications. Telemetry with the RTUs is at 300 Baud using Aquatrol's 2150/2350 FSK tone standard.
The CrosStar MT-200B W1300 Master Modem provides complete master control of any RT-100 or W1300 system, based upon information and control passed from the MMI display/control programs noted above. The SCADA modem interprets the standard Allen Bradley DF1® messaging, and provides the necessary conversions of both speed and data format, to make a seamless exchange to the controlling computer and MMI. No additional software patches or drivers are required, since DF1® is a widely acceptedprotocol standard. The CrosStar MT-200B addresses up to 98 RTU’s, as in the original W1300 system design.
The MT-200B appears as one PLC-5 on the RS-232 connection, and the entire W1300 telemetry system appears as I/O points on that PLC. It occupies DataHighway address 1, and other PLCs may be installed on the same network at other addresses, as in any ordinary installation. The MT-200 needs no configuration, because it installs itself when connected to an operating MMI software computer. The modem contains all necessary conversions for address, status and analog signals used by the SCADA system. It properly converts data in both directions without any operator configuration. Digital and Analog values are automatically routed properly to the MMI.
