DeviceNet setup and configuration (typical)
Hardware Setup
Consider the example of a DeviceNet network containing the following devices:
•
A computer running RSNetWorx™ for DeviceNet software
•
A 1747-SDN-communication module interfacing an SLC 500 processor with the
DeviceNet network
•
1770 KFD RS232 to DeviceNet module
•
MM300 Relay.
Wiring up the network
NOTE
NOTE:
Ensure that power to the devices is switched off while making the connections. Make sure
each end of the DeviceNet trunk cable is properly terminated with a 120-ohm resistor.
1.
Connect the RS-232 connector on the 1770-KFD-communication interface module to
one of the serial ports on your computer workstation (COM1).
2.
Connect the DeviceNet connector on the 1770-KFD module to a DeviceNet cable. The
terminal designations are as shown in the table below:
