1. Assign the logical drive number: 4,
select the module type: DMP–C.
2. Perform an NCK Reset to set up the bus.
3. Set the number of analog inputs and outputs:
Analog inputs: MD10300 = 2, analog outputs: MD 10310 = 1.
Set the number of digital input and output bytes:
3 bytes for dig. inputs, 2 of these bytes external and 1 internal:
MD10350 = 3,
4 bytes for dig. outputs, 3 of these bytes external and 1 internal:
MD10360 = 4.
4. Assign the analog inputs to the hardware:
MD 10362 [0] = 01040201
1st input byte
Slot on terminal block
Logical drive number
Always = 01 on 840D
MD 10362 [1] = 01040301
5. Assign the analog outputs to the hardware:
MD 10364 [0] = 01040101
6. Assign the digital inputs to the hardware:
MD 10366 [0] = 01040602
2nd input byte
Slot on terminal block
Logical drive number
Always = 01 on 840D
7. Assign the digital outputs to the hardware:
MD 10368 [0] = 01040401
MD 10368 [1] = 01040502
8. Set the weighting factors for the analog inputs/outputs:
MD 10320 = 10000
MD 10330 = 10000
9. Set the option: Programmed analog output
