CS11-L Current Transformer

6.6.1 Example CR10X program reading 32 CS11-L Current Transformers

;{CR10X}

; Example program for CS11-L

;

; Program to test the CS11-L sensor on a CR10X datalogger

; and AM1632 Multiplexer.

;

*Table 1 Program

01: 30 Execution Interval (seconds)

; Turn on the multiplexer

1: Do (P86)

1: 41 Set Port 1 High

2: Excitation with Delay (P22)

1: 1 Ex Channel

2: 0 Delay W/Ex (0.01 sec units)

3: 15 Delay After Ex (0.01 sec units)

4: 0 mV Excitation

3: Beginning of Loop (P87)

1: 0000 Delay

2: 32 Loop Count

; Clock multiplexer to next channel

4: Do (P86)

1: 72 Pulse Port 2

5: Excitation with Delay (P22)

1: 1 Ex Channel

2: 0 Delay W/Ex (0.01 sec units)

3: 1 Delay After Ex (0.01 sec units)

4: 0 mV Excitation

6: Do (P86)

1: 1 Call Subroutine 1

; This part of the program will calculate the rms Amperage

; Standard Deviation in this part of the code works mathematically the same

; as rms calculation, and it is easier to program this way. The rms

; value is calculated and stored back into an input location for further

; processing if needed.

7: Do (P86)

1: 2 Call Subroutine 2

8: Step Loop Index (P90)

1: 2 Step

9: Z=X (P31)

1: 2 X Loc [ BurstAmps ]

2: 4 -- Z Loc [ CS11_1 ]

1 2 ... 20 21 22 23 24 25 26 27 28 29 30 ... 35 36
