THE diagnostic power of the PNOZmulti safety controller is now accessible using a PMIopen touch screen, with the release of a new PNOZ driver by Pilz Safe Automation .
Written by InduSoft for its Web Studio software, the PNOZ driver enables users to view data such as the I/O status, LED indicator status and error stack.
Because there is no need for an additional communications module, even the base PNOZmulti module delivers the messaging and diagnostics normally associated with more sophisticated equipment - a connection to the built-in RS232 serial port is all that is required.
Three models of PMIopen are available, all of which are delivered with Microsoft Windows CE 3.0 pre-installed:
* PMI o215 - with a 5.7-inch STN display giving 256 colours.
* PMI o226 - with a 10.4-inch TFT display giving 65535 colours.
* PMI o231 - with a 12.1-inch TFT display giving 65535 colours.
All are compact and robust, resistant to vibration and provide protection against dust, water sprays and a wide variety of aggressive chemicals.
Each device benefits from 64MB of SDRAM and a 32MB Flash-EPROM. Connections to other devices, such as CompactFlash memory cards, are also easily accommodated with PCMCIA slots.
Interfaces include serial ports (RS232/485), USB, ethernet and a PC/104 slot for fieldbus connections.
The PNOZmulti safety controller, PMIopen touch screen interface and driver are all available from Pilz Safe Automation.
