Adapter Boards – External control devices such as a PLC, discrete
operators devices, etc., are interfaced with the Main Control Board through
one of the two microbus ports, labeled Port A (J7) and Port B (J6) on the
Main Control Board. The microbus is a 60 line bus designed specifically
for the transfer of data between microprocessors. The microbus is used on
the Main Control Board to transfer data between devices on the board.
Additionally, hardware on the Main Control Board allows data transfer
between the microprocessor on the Main Control Board and external
devices through the two microbus Ports.
Information coming from external devices must be changed first to the
format required by the microbus before being input to the microbus Port.
The processing of data is accomplished through the use of the following
adapter boards:
