How do I determine an 890 drive TAG NUMBER so it can be used in DSE890?

1. Multiply the value to the left of the decimal by 32 and add the value to the right of the decimal to it.
   For example: we will try to determine the TAG NUMBER of DIGITAL OUTPUT 4 so it can be written to in DSE. Presently Digital Output 4 is not available in the DSE template, so it must be written to using a TAG WRITER if it is to be used.
   1. Go to the MMI keypad of the 890 drive.
   2. Go to SETUP / INPUTS & OUTPUTS / DIGITAL OUTPUT / DIGITAL OUTPUT 4.
   3. Go to VALUE.
   4. Keep holding the M key and the PREF parameter will display. It should be 147.01.
   5. The PREF is determined by the following procedure:
      1. The PREF is 147.01.
      2. Take the first value of 147 and multiply it by 32. Thus 147 x 32 = 4704.
      3. Then add the second value of ".01", which is actually 01 or 1.
      4. Thus 4704 + 1 = 4705.
      5. Thus the PREF = 4705.
      6. Then in DSE go to BLOCK / 890 and select LOGIC WRITER and enter 4705 for TAG NUMBER. In this example since a Digital Output is a Logic value, a Logic Writer is used. Different parameters may be an Integer, Logic or Value.
      7. In the above example if the PREF was 147.10, then:
      8. Take the first value of 147 and multiply it by 32. Thus 147 x 32 = 4704.
      9. Then add the second value of "0.10", which is actually 10.
      10. Thus 4704 + 10 = 4714.
      11. Thus the PREF = 4714. You will use this as a TAG NUMBER in DSE.
