The wide variety of Grayhill I/O modules and racks provide a sound foundation for solving today's industrial control and data acquisition problems. The following list is a summary of the controllers available, please click on the first line description for a more detailed view.

OpenLine

PC Based Controller - OpenLine

Whether you need selected I/O, remote I/O or a complete PC-based control or data acquisition system, Grayhill's new OpenLine makes your job easier. Its power supply, controller, I/O bricks and I/O modules clip together in a sleek, modular design. Its open programming environment gives you the choices you want. The result: streamlined programming, implementation, upgrades and maintenance.

Software
IEC 1131-3 compliant programming tools or C++

Optomux Based Controller - MicroDAC

Controls/monitors up to 32 analogue and/or digital I/O modules; executes on-board programs; network up to 64 MicroDACs per host serial port; DIN rail or panel mountable metal enclosure.
ARCNET SBX Boards for MicroDAC can replace the basic RS422/485 master/slave communication used to network MicroDAC's with a host computer, creating a true distributed control and data acquisition system.
Digital I/O Expansion Board for MicroDAC decreases the number of MicroDAC's required in applications where there are high concentrations of I/O at some of the locations.

DacNet

DeviceNet Based Controller - DacNet

The DacNet controller interfaces Grayhill analogue and digital single point I/O modules with DeviceNet - a low cost communications bus for industrial devices such as limit switches, photo-electric switches, valves, motor starters, operator interfaces, PLC's, and PC's The DeviceNet bus is based on a broadcast-oriented, open communications protocol the Controller Area Network (CAN).

LonWorks Based Controller - Microlon

The Microlon controller combines the power of LONWORKS technology with Grayhill standard industrial I/O racks and modules. Microlon controllers may be distributed over great distances yet provide seamless interoperability. The robust communication protocol LonTalk is built into the firmware of the Neuron chip, the heart of LONWORKS technology. The LonTalk protocol follows the (7 layer) OSI Reference Model for network protocols. This technology is becoming the defacto standard for interoperability. This frees the user from worrying about network communication protocols.
