Port 70 and port 80
The port numbers 70 and 80 are used to transmit 16 bit binary numbers. The transmission is
sequential and divided into four sections with four bits each time. The robot system and the
peripherals "shake hands" between each section of four bits.
The table below shows the coupling between inputs/outputs and ports 70 and 80. The number
of bits is 4 x 4, and the value of the number register can be between -32.768 and +32.767

Remote I/O, RIO (Remote Input Output)
The control system can be equipped with one RIO-board. The RIO-board can be programmed to
32, 64,96 or 128 digital in- and outputs, depending on how many other digital I/O boards that
are installed in the system. The maximum number of digital in- and outputs the system can
handle is 128. The board should be placed to the left of the last I/O-board in the frame, this
gives the most freedom to choose configuration on the RIO-board.
On the front of the board there are 32 leds. The first 16 is used to indicate status for the first
16 inputs on the RIO-board, the other 16 is for indication of the first 16 outputs.
The RIO-board is to be connected to an ALLEN BRADLEY PLC with a screened, two conductor
cable.
NOTE! The robot system does not recognise a malfunction of the communication to
the PLC. Inputs maintains the status of the last update from PLC.
