Hardware
The CANbus to DeviceNet Transducer Gateway is provided in a Hoffman type NEMA 12 metal
enclosure with screw terminals for I/O connections and power. The enclosure is 10.375 by 11.75 inches
without cables and is powered by 24 VDC. The enclosure contains a processor board with expansion
facilities via PC104. The processor is a 40 MHz 80386 contained on a PC104 board. PC104 modules
stacked on the baseboard provide additional capabilities. Connections to field I/O are made through a series
of screw terminals along the edge. Connections are provided for a CRT, Keyboard and a serial connection.
In normal use these are unconnected. For setup the serial channel can be used.
Processor
33 MHz 80386 with 4 Mbytes of DRAM. ROM-DOS version 6.22 software is installed.
PC 104 boards
CANbus interface modules
The Aim104 CAN module is an 8-bit PC/104 module providing a single channel, optically
isolated CAN bus interface. In addition the board is fitted with an EEPROM for configuration information
and an output port for driving three bicolor LED’s. The AIM104 CAN modules are connected via ribbon
cable to two SERT-DNET pluggable Device Net headers mounted to the front cover.
Connections made to the Can Bus transducer network and the Device Net are made via two 5-pin
Device Net compatible screw terminals. CAN bus cabling should use the Trunk and Drop method with a
120-ohm termination resistor at the end of the trunk. The AIM104 CAN module provides termination at
the controller end.
Two AIM104 CAN modules are installed in the system.
