PMD 200 Master Message Display

The PMD 200 Master Message Display was designed to give you more display continuity and flexibility than ever before. This extraordinary low-cost unit is an intelligent, alphanumeric display panel, which is user programmed with individualized messages. Its compact size reduces space previously required for annunciator panels and indicator lights. Unlike annunciator panels, the PMD 200 can be used to provide complete information of machine or process status, operator prompting, and fault indicators.

The PMD 200 Master Message Display comes with 2-line display with 20 vacuum fluorescent characters 0.433" (11.0 mm) high. Interfacing to this unit is not a problem either. The PMD 200 Master Message Display comes with drivers that enable it to interface directly with over 30 brands and/or models of PLCs.

Messages are programmed into the Master using any ASCII terminal or PC with an RS-232C interface. Message programs can be stored on digital tape and reloaded into one or more message displays at any time. The PMD 200 can be interfaced to a printer, either to print the entire program or to print individual messages as selected.

The RS-422A port provides communication with up to 65,520 Slave displays that can be addressed both individually or in groups. Another RS-422A port provides computer interfacing capability, which allows a computer to share control of the PMD 200’s operation.
