arbellah Posted April 6, 2016 Report Share Posted April 6, 2016 I ordered a v130 PLC and a V100-17-CAN to pair with it. I instealled the CAN as the directions stated, however there is a resister? I assume is what it is that was shipped with the CAN. The label states it is SA\RES-121. Where does this go/what is it? Thank you! Quote Link to comment Share on other sites More sharing options...
s.pratt Posted April 7, 2016 Report Share Posted April 7, 2016 Hello, The SA\RES-121 is a 121 ohm terminating resistor for the CANbus network. If our PLC will the a physical end on the CANbus network, you must place this 121 ohm resistor across the DATA lines to terminate the network. You can see a disgram of this wiring with the terminating resistor in the help files of VisiLogic. Networks (CAN, Serial) \ CANbus Networking. There is a green link for the Wiring Diagram - click on it to view this section. Hope this helps. Quote Link to comment Share on other sites More sharing options...

MVP 2021 Joe Tauser Posted April 9, 2016 MVP 2021 Report Share Posted April 9, 2016 The CANbus card may or may not have a resistor in it. If you can find a pair of standard 120 ohm resistors it will work fine. Joe T. Quote Link to comment Share on other sites More sharing options...
