Introduction

This article covers how to set up the analog expansion modules for the CP series PLCs.

Delete

Warning

Analog expansion units won't read ANY values until their range code has been set.

Delete

Warning

The range code must be written to the IO area every time the CPU is power cycled.

Delete

Warning

Unused analog inputs must be deactivated in the range code. None of the expansion unit input will work if an input is missing.

Step 1

Wire the analog inputs/outputs. See Appendix E.

Step 2

Determine the range codes required for your application. See the below example for determining your range codes. Appendix F contains the full reference of range codes.

CP1W-AD041 Range Code Example

We will use 3 analogue inputs for the example

Input 1 = -10V to 10V
Input 2 = 0 to 10V
Input 3 = 4 to 20mA
Input 4 = Not in use

The below graphic shows how the range codes are structured

Input 1 set data = Input Use(Yes, 1), Averaging (No, 0), Range Code (-10 to 10V, 00)
Input 2 set data = Input Use(Yes, 1), Averaging (No, 0), Range Code (0 to 10V, 01)
Input 3 set data = Input Use(Yes, 1), Averaging (No, 0), Range Code (4 to 20mA, 10)
Input 4 set data = Input Use(No, 0), Averaging (No, 0), Range Code (N/A, 00)

Therefore the n+1 and n+2 are:

	15	14	13	12	11	10	9	8	7	6	5	4	3	2	1
n+1	1	0	0	0	0	0	0	0	1	0	0	1	1	0	0
n+2	1	0	0	0	0	0	0	0	0	0	0	0	1	0	1

CP1W-DA041 Range Code Example

In this example we will use CP1W-DA042 which has 4 outputs. CP1W-
DA021 only has 2 outputs, so only word n+1 can be used.

We will use 3 analogue inputs for the example

Output 1 = -10V to 10V
Output 2 = 0 to 10V
Output 3 = 4 to 20mA
Output 4 = Not in use

The below graphic shows how the range codes are structured.

Output 1 set data = Output Use(Yes, 1), Range Code (-10 to 10V, 000)
Output 2 set data = Output Use(Yes, 1), Range Code (0 to 10V, 001)
Output 3 set data = Output Use(Yes, 1), Range Code (4 to 20mA, 100)
Output 4 set data = Output Use(No, 0), Range Code (N/A, 000)

Therefore the n+1 and n+2 are:

	15	14	13	12	11	10	9	8	7	6	5	4	3	2	1
n+1	1	0	0	0	0	0	0	0	1	0	0	1	1	0	0
n+2	1	0	0	0	0	0	0	0	0	0	0	0	1	1	0

CP1W-MAD11 Range Code Example

We will use 2 analogue inputs and 1 analogue output for the example.

Input 1 = -10V to 10V
Input 2 = 4 to 20mA
Output 1 = 4 to 20mA

The below graphic shows how the range codes are structured

Input 1 set data = Range Code (-10 to 10V, 000)
Input 2 set data = Range Code (0 to 10V, 010)
Output 1 set data = Range Code (4 to 20mA, 100)

Therefore the n+1 is:

	15	14	13	12	11	10	9	8	7	6	5	4	3	2	1	0
n+1	1	0	0	0	0	0	0	1	0	0	0	1	0	0	0	0

CP1W-MAD44 Range Code Example

We will use 3 analogue inputs and 3 analogue outputs for the example

Input 1 = -10V to 10V
Input 2 = 0 to 10V
Input 3 = 4 to 20mA
Input 4 = Not in use
Output 1 = -10V to 10V
Output 2 = 0 to 10V
Output 3 = 4 to 20mA
Output 4 = Not in use

The below graphic shows how the range codes are structured for CP1W-MAD44

Input 1 set data = Input Use(Yes, 1), Average(No, 0), Range Code (-10 to 10V, 00)
Input 2 set data = Input Use(Yes, 1), Average(No, 0), Range Code (0 to 10V, 01)
Input 3 set data = Input Use(Yes, 1), Average(No, 0), Range Code (4 to 20mA, 10)
Input 4 set data = Input Use(No, 0), Average(No, 0), Range Code (N/A, 000)
Output 1 set data = Output Use(Yes, 1), Range Code (-10 to 10V, 000)
Output 2 set data = Output Use(Yes, 1), Range Code (0 to 10V, 001)
Output 3 set data = Output Use(Yes, 1), Range Code (4 to 20mA, 100)
Output 4 set data = Output Use(No, 0), Range Code (N/A, 000)

Therefore the n+1 to n+4 are:

	15	14	13	12	11	10	9	8	7	6	5	4	3	2	1
n+1	1	0	0	0	0	0	0	0	1	0	0	1	1	0	0
n+2	1	0	0	0	0	0	0	0	0	0	0	0	1	0	1
n+3	1	0	0	0	0	0	0	0	1	0	0	1	1	0	0
n+4	1	0	0	0	0	0	0	0	0	0	0	0	1	1	0

CP1W-MAD42 Range Code Example

We will use 3 analogue inputs and 1 analogue output for the example

Input 1 = -10V to 10V
Input 2 = 0 to 10V
Input 3 = 4 to 20mA
Input 4 = Not in use
Output 1 = -10V to 10V
Output 2 = Not in use

The below graphic shows how the range codes are structured for CP1W-MAD44

Input 1 set data = Input Use(Yes, 1), Average(No, 0), Range Code (-10 to 10V, 00)
Input 2 set data = Input Use(Yes, 1), Average(No, 0), Range Code (0 to 10V, 01)
Input 3 set data = Input Use(Yes, 1), Average(No, 0), Range Code (4 to 20mA, 10)
Input 4 set data = Input Use(No, 0), Average(No, 0), Range Code (N/A, 000)
Output 1 set data = Output Use(Yes, 1), Range Code (-10 to 10V, 000)
Output 2 set data = Output Use(No, 0), Range Code (N/A, 0)

Therefore the n+1 and n+2 are:

	15	14	13	12	11	10	9	8	7	6	5	4	3	2	1
n+1	1	0	0	0	1	0	0	0	1	0	0	1	1	0	0
n+2	1	0	0	0	0	0	0	0	0	0	0	0	1	0	1

Step 3

Write the range codes to the IO area to initialise the analogue input/output configuration. See Appendix A for information on how to determine the memory areas your expansion module is using. The below example goes over how to write the range codes to your expansion cards.

Appendix A - Analog Memory Areas

Expansion Units and Expansion I/O Units are allocated I/O bits in the order the Units are connected starting from the CPU Unit. When the power to the CPU Unit is turned ON, the CPU Unit checks for any Expansion Units and Expansion I/O Units connected to it and automatically allocates I/O bits. See example below for how memory is allocated to analog input and output areas.
