LPC1 to LPC48 LPC1 Low Pulse count using Digital IO cards in pulse
count mode
Pen Pn Get the value of Pen n (1 to 96)
Pen Minimum Value PnMINU Gets the Pen Minimum value n = 1 to 96
Pen Maximum Value PnMAXU Gets the Pen Maximum value n = 1 to 96
Pstv PSTVx Get the persisted Global variable x. Persisted
global variables maintain their value through a
power cycle. There is a maximum of 50 per-
sisted global variables.
PRC PRC Power Relay Counter
Pulse Inputs (AI slots) HPULn Get the Pulse frequency from the Pulse card n

Pulse Inputs (DIO Slots) LPULn Get the Pulse frequency from the Digital Input
card when in Pulse mode n = 1 to 48 (1kHz
Max)
RT Compensation RTCOMPn Get RT Compensation value for channel n (1 to
48) Units mV
RT Calibration RTCALn Get RT Calibration value for channel n (1 to
48). Units mA
Totaliser Tn Get Totaliser value n = 1 to 96
