When the Bus Controller configuration screen appears, some default selections are already displayed.
These selections can be used as is, or changed for the application. Until a valid configuration is stored
to the PLC CPU, the Bus Controller will not operate on the Bus, and its Channel OK LED will not
light.
Bus Addr: Ordinarily, the Device Number (Bus Address) assigned to a Bus Controller is 31. Any
number from 0 to 31 can be used.
Baud Rate: All devices on a bus must use the same baud rate: l53.6 Kbaud standard, 153.6 Kbaud
extended, 76.8 Kbaud, or 38.4 Kbaud. Selection of a baud rate depends on the application, as explained
in the Genius I/0 System User's Manual.
The selection made on this screen determines the baud rate for the Bus Controller. Other devices on the
bus must also have their baud rate set.
Error Rate: This entry determines how the Bus Controller will respond to errors on the bus. If the Bus
Controller should drop off the bus when a specified number of errors occur within a 10-second period,
enter that number of errors here. If the Bus Controller should remain on the bus when errors occur and
try to maintain communications, enter 0 here.
CAUTION
If the bus includes a Bus Switching Module, the Error Rate MUST be set to 0. Otherwise, the
Bus Controller may drop off the bus when the BSM is switching a block to the bus.
