DeviceNet Plug-in – 2080-DNET20 Appendix 5
Calculate Voltage Requirement
SUM {[(Ln * (Rc)) + (Nt * (0.005))] * In} < 4.65 V
Where:
Ln = Length in meter or feet
Rc = Resistance of the cable per meter or feet
(Kwiklink flat media = 0.019 ohms/meter or 0.0058/feet)
Nt = Number of the node starting from 1 close to power supply and increasing.
0.005 = Nominal contact resistance used for every connection to the trunkline
In = Current drawn from the cable system by the device.

RA_DNET_MASTER
This UDFB sets the 2080-DNET20 scanner to RUN mode.
IMPORTANT
To calculate for percentage of loading, divide the total voltage
calculated from the above formula by 4.65.
