Selecting the node address via the digital inputs DIN0 ... DIN5
You assign the node address to the controller by adding to the preset slave node number
an offset via DIN0 ... DIN5.
1. Open the Parameters
W Fieldbus W Profibus... W Operating parameters... menu.
931E_020, 931E_22
2. Enter the desired value in the Slave node number input box.
3. Click on the + Offset (DIN) (inactive) button (see arrow in the screenshot of the
"Profibus" dialog box).
– The Digital inputs dialog box opens.
4. Tick the Offset node number (field bus) check box.
– Tick the AIN’s used as DIN’s check box (if necessary) to use DIN0 ... DIN3 as well for
the offset.
– Adjustable offset: 0 ... 63 with DIN0 ... DIN5 or 16, 32, 48 with DIN4, DIN5
– Click on the OK button.
5. Set the digital inputs DINx for the desired offset.
Calculation of the offset:
Offset = DIN0 × 2
0 + DIN1 × 2 1 + DIN2 × 2 2 + DIN3 × 2 3 + DIN4 × 2 4 + DIN5 × 2 5
Example:
The node address of the controller is to be "35". In the Slave node number input box "3"
is entered. So the offset must be "32":
Offset = DIN0 × 2 0 + DIN1 × 2 1 + DIN2 × 2 2 + DIN3 × 2 3 + DIN4 × 2 4 + DIN5 Ч 2 5
32 = 0 Ч 2 0 + 0 Ч 2 1 + 0 Ч 2 2 + 0 Ч 2 3 + 0 Ч 2 4 + 1 Ч 2 5
6. Click on the Save & Reset button to save the settings.
– Important: After clicking on the button, the states of the digital inputs are read
once. The offset is added to the slave node number. Subsequent changes have no
effect.
– After saving, the assigned node address is displayed in the Effective slave node
number box.
