Accessory 36E

USING ACC-36E WITH TURBO uMAC 19

Bipolar PLC Example

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

example uses M5001, M5003–M5006, and P2001–P2016.

#define DataRead_Low M5001 ; Lower 12-bit Data Read register

#define DataRead_High M5003 ; Higher 12-bit Data Read register

#define LowADCReady M5005 ; Low ADC Ready Bit

#define HighADCReady M5006 ; High ADC Ready Bit

DataRead_Low->Y:$078C00,0,12,S ; Signed for bipolar

DataRead_High->Y:$078C00,12,12,S ; Signed for bipolar

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
