Digital inputs/outputs

There are 4 digital inputs/outputs available on the reader. The outputs can be configured in
the WBM. You will find more information on this in the section "The "Settings - Digital
outputs" menu item (Page 72)". The request and control are via the controller. You can
control the addresses of the inputs/outputs via a 1-WORD subsegment of the process image
of the reader/CM. You can enter the addresses using STEP 7 or Studio 5000 Logix Designer
in the properties of the reader in the parameter "Digital inputs/outputs". You can access the
digital inputs/outputs via the byte with the lower value address.
The structure of this byte and the assignment to the digital inputs/outputs is shown below:
