Setpoint Adapter Boards

These analog setpoint adapters enable the user to set 8 analog setpoint values. The analog val-
ues (0 to 255) of the potentiometers are read into the controller and used as default setpoint val-
ues for timers, counters and data registers by the user's PLC programs.
Each potentiometer value can also be read as an 11 position rotary switch (positions 0 to 10).
Setpoint value polling is performed in the PLC program using the dedicated instruction VRRD.
The position of an rotary switch is read using the VRSC instruction.
The analog setpoint adapters are installed in the expansion slot of the base unit. No additional
power supply is required for operation.
