Expansion modules connection direction

[Pokstas]

Hi , i have system with 3DI and 3TO expansion modules, i need install new AO6X analog output module, can i connect after 3DI/3TO or must be before DI/TO modules. Is there any recommendation how should be connected expansion modules?

Hello,

 

You may place the module anywhere you wish in the expansion chain.  It must match the same position as the position in the hardware configuration, though.  So if in the program, it is the second module from the left, you must also place it second in line after the expansion module when wiring.

 

Hope this helps.
