4DI Module 6ES7131-4BD01-0AA0 Addressing Issue

Hello experts,

I am adding two 4DI modules 6ES7131-4BD01-0AA0 in ET200S IM151-1AA06-0AB0 in the Step7 V5,5 Software.

I would like to address them as follows:

one module: I50.0 to I50.3 (which is happening fine)

other module: I50.4 to I50.7 (here is the problem*)

*The other module takes the start address from new byte (i.e I51.0 in this case), but I want to use the same byte but different bits as mentioned above.

I know there is some tiny problem that I am making, but I am unable to understand it. I have also read the help section but it isn't working.

Thank you in advance!

 Hello jack_Iohana,

I'm afraid that's not possible. Take a look picture.

Thank you Soble for the response.

actually I am working on the already pre-programmed software, in which all other such 4DI modules are addressed in the bit-wise manner. 

But when I add two new modules, I cannot address them in the same manner. This is definitely possible otherwise it will be futile to reserve one whole byte for 4bit addressing.

Hello Jack_Iohana,

Yes you were right, take a look over there Group ET200S 4DI modules

Hello Soble.

I solved the issue. Thank you!

There was a pack address button when I selected the module for addressing.
