ADS Process Image
The process image is sub-divided into input image and output image. The Coupler Box first maps all complex (byte-oriented) Extension Boxes (IE3xxx, IE4xxx, IE5xxx, IE6xxx), into the process image in the order in which they are inserted in IP-Link. Afterwards all digital Extension Boxes (IE1xxx, IE2xxx) are added to the process image.
The complex (byte-oriented) Extension Boxes are always mapped with the following settings:
- complete evaluation
- Word alignment
- Intel format
Example 1:
IL2301-B900 (4DI, 4DO)
2 x IE1001 (8DI)
2 x IE2002 (8DO)
1 x IE3312 (4 AI)
1 x IE4132 (4AO)
Position | Module | Input %I..Byte Offset | Output %Q..Byte Offset |
|---|---|---|---|
1 | IE3312 | 0...7 | 0..7 |
2 | IE4132 | 8...15 | 8...15 |
3 | IL2301 | 16.0...16.3 | 16.0...16.3 |
5 | IE1001 | 16.4...17.3 | - |
6 | IE2002 | - | 16.4...17.3 |
