The T1K–MODBUS Base Controller is a slave module that functions as a controller
for Terminator I/O on a MODBUS network.
Note: It is recommended to use the T1K–MODBUS Base Controller in a "scan
based" (polled) control system rather than in an "event–driven" control system. As a
slave, the Base Controller does not have the ability to report an error condition to the
MODBUS network master. Thus, polling a slave on a regular basis will detect a slave
error condition promptly, whereas an event–driven control system will not detect a
slave error condition until the next event is addressed to a slave in error.
The Base Controller has the following features:
•
Status LEDs
•
MODBUS Port
•
Serial Port (RJ12)
•
Unit Address Switches
•
Output Enable/Disable Switch
•
DIP Switch (located on right side of unit)
