Accessory 36E

USING ACC-36E WITH TURBO uMAC 18

ADC Manual Read Example PLCs

Ultimately, the procedure above can be implemented in a PLC script to read all channels consecutively

and consistently, creating a “custom automatic” function, as seen in the following examples.

Unipolar PLC Example

Setting up Turbo UMAC with an ACC-36E at base address $078C00 with all 16 ADCs as unipolar. This

example uses M5000, M5002, M5004–M5006, and P2001–P2016.

#define DataRead_Low M5000 ; Lower 12-bit Data Read register

#define DataRead_High M5002 ; Higher 12-bit Data Read register

#define ChSelect M5004 ; Channel Select Pointer

#define LowADCReady M5005 ; Low ADC Ready Bit

#define HighADCReady M5006 ; High ADC Ready Bit

DataRead_Low->Y:$078C00,0,12,U ; Unsigned for unipolar

DataRead_High->Y:$078C00,12,12,U ; Unsigned for unipolar

ChSelect->Y:$078C00,0,24,U ; Channel Select

LowADCReady->Y:$078F30,5,1 ; Low ADC Ready Bit

HighADCReady->Y:$078F31,5,1 ; High ADC Ready Bit

#define ADC1 P2001 ; Channel 1 ADC storage

#define ADC2 P2002 ; Channel 2 ADC storage

#define ADC3 P2003 ; Channel 3 ADC storage

#define ADC4 P2004 ; Channel 4 ADC storage

#define ADC5 P2005 ; Channel 5 ADC storage

#define ADC6 P2006 ; Channel 6 ADC storage
