Configuration of analog modules

CJ1W-AD0?1(-V1)

CJ-series cards/modules are divided into three main groups: 

 - Standard I/O modules

 - Special I/O (SIOU) modules

 - CPU bus modules. 

Analog cards fall under the Special I/O module group.

Indicators on the CJ1W-AD0X1:

Wiring of the cards:

Front view of the cards:

Setting of the rotary switches:

Set the desired module number (MACH No.) using the rotary number switches on the front of the module. No special modules may share the same module number. Each module requires/reserves two fixed areas in the PLC memory. These areas depend on the selected module number.

Memory allocation example:

The following two memory areas are occupied by

the analog module:

CIO 2XY0–2XY9 and D2XY00–D2XY99

Example: Switch ×10^ 1 (X) = 3 and switch ×10^ 0 (Y) = 1 

This would result in module number (MACH No.) 31 and memory allocation CIO 2310–2319 and D23100–23199.

Setup through the IO-table:

By opening the IO table in the project tree, you can double-click on the AD card and make adjustments before downloading to the card.

Setup through code:

As seen above. All of the settings have their place in the D2XY00 memory.

By writing enable/disable to the D2XY00 word and range-codes to the D2XY01 word you can set the card up through code. This will make your application more reliable as the user don't have to use the IO-table and download new settings if a card needs replacement.

The actual input value ends up in CIO2XX1->. So for our Card #31 this will be:
