Posted 16 Feb 2016 (edited) Hello All, We have a TRD-NA 10 Bit Abosolute Encoder with a resolution of 1024. How do I hook this absolute Encoder to Omron CJ2 Series PLC to get a position???? Do I need a specific Card? Here's wiring scheme for TRD-NA Blue - 0V Brown - 12/24 V Black - Bit 0 Red - Bit 1 Orange - Bit 2 Yellow - Bit 3 Green - Bit 4 Purple - Bit 5 Gray - Bit 6 White - Bit 7 Black/White - Bit 8 Red/White - Bit 9 Shield - GND Edited 16 Feb 2016 by netdomain Share this post Link to post Share on other sites
Posted 16 Feb 2016 The CJ2 Series primarily support incremental encoder signals. The only absolute encoder supported is for the CJ2 is an SSI type using the CJ1W-CTS21-E expansion card. Share this post Link to post Share on other sites
Posted 17 Feb 2016 You would use a standard DC Input card and monitor the position as a CIO word... Share this post Link to post Share on other sites

If I am looking at the right encoder, it is a Gray Code encoder. A standard input module would allow you to bring each input into the PLC and then you could use the GRAY_BIN instruction to convert from Gray code to Binary (integer) format.
