Terminating resistor
A DeviceNet line can have max. 63 participants. The participants are
ƒ the connected basic devices
ƒ the DeviceNet master (scanner)
ƒ all other components which take part in the communication.
Inthere, the basic devices withplugged-on communicationmodules and the
DeviceNet master can communicate.
A PC with installed software (e.g. RSNetWorx) is used to integrate the
communication modules.
Note!
Please observe that
ƒ
the shield on the voltage supply is to be connected together
with the ”V-” connection to GND once. For this, use the centre
point of the DeviceNet line, if possible.
ƒ
for each participant the shield of the DeviceNet cable is only
connected to the ”shield” connection of the plug connector.
ƒ
the DeviceNet line is terminated by 120-Ohm resistors at both
ends.
