When a controller is integrated into a CANbus ISC network, the data contained in certain system operands is continuously broadcast to the network, together with the controller's unique ID number. The data is contained in 16 System Bits (SB 200 to SB 215 (16 Inputs (I 0 to I 15), and 2 System Integers (SI 200 and SI 201).
In order to enable a networked controller to read the values from another networked controller, place the desired function in the net. In the Select Operand Address box, click on the Network tab, then select the ID of the target controller and the desired operand.
