Connect the Logic Reader output, to the block to turn off /on. In this case, it is connected to the Or gate. Digital Input 8 is located at terminal X15-08 on the 890 drive.
  2. To configure DIN 9 /DOUT 2 as a Digital Input follow the above instructions but set the Logic Reader for Tag 514. Digital Input 9 is located at terminal X15-09 on the 890 drive.
  3. These Digital Inputs 8 & 9, operate the same as Digital Inputs 1-7. If 24vdc is applied to the appropriate hardware terminals, the Digital Inputs go True. These inputs are independent of each other. One can be an input and the other can be an output.
