Trio Motion Coordinator MC206 User Manual

8-80 Trio BASIC Commands
System Parameters and Commands
Trio Motion Technology
In addition to using the CAN command to control CAN channels, Trio is introducing
specific protocol functions into the system software. These functions are dedicated
software modules which interface to particular devices. The built-in CAN channel
will automatically scan for Trio I/O modules if the system parameter
CANIO_ADDRESS is set to its default value of 32.
The Motion Coordinator CAN hardware uses the Siemens 81C91 CAN interface chip.
This chip can be programmed at a register level using the
CAN command if neces-
sary. To program in this way it is necessary to obtain a copy of the chip data sheet.
The
CAN command provides access to 10 separate functions:
CAN(channel#,function#,...)
