Operator interfaces

Building on the success of the previous touch screen PMI ranges, the fourth-generation Pilz operator interface and diagnostic display units offer improved performance.

Both the PMIvisu and PMIopen series are available in the fourth-generation specification, with the PMIvisu models being suitable for diagnostics and visualisation with PNOZmulti modular safety systems, PSS programmable safety and control systems, and SafetyBUS p networks. Furthermore, due to the use of standardised interfaces, the fourth-generation PMIvisu units can be used as graphics systems for all common programmable logic controllers. If custom software needs to be run on the display, then the versatile PMIopen operator terminals can be specified.

The main feature of the units is the hardware platform that features a high-performance 624 MHz CPU with 128 MB of RAM nano 64 MB of flash memory. Brighter, high-contrast TFT displays have also been incorporated to improve legibility, and the LPT, VGA and USB interfaces that were previously optional are now integrated as standard. Ethernet (10/100 Mbps) and dual serial ports are also standard, and users can retrofit fieldbus modules for use with Modbus RTU, Modbus TCP/IP, Profibus DP and CANopen.
