Aux I/O Outputs for ConveyLinx-Ai Family
In certain applications, it may be desired to have the PLC actuate a device along the conveyor (i.e. illuminate a light or energize a solenoid coil, etc.). With the ConveyLinx network this can be done without installing a separate PLC I/O system to do this. In EasyRoll, simply select NONE from the Aux I/O Pin 2 Usage tab and this allows the PLC to have access to the Aux I/O pin and configure it to be either an input or an output and use it accordingly.

Control Port Outputs for ConveyLinx-ERSC Family
By default, in ZPA mode, the PLC does not have control of the local connected module’s Control Port output signals. The default function of the Control Port output signals is to be energized when the Control Port’s corresponding zone is occupied. In certain applications, it may be desired to have the PLC actuate a device along the conveyor (i.e. illuminate a light or energize a solenoid coil, etc.). With the ConveyLinx network this can be done without installing a separate PLC I/O system to do this. Using EasyRoll software, one or both Control Ports can have their function switched from internal ZPA logic control to be controlled by the PLC.
