Posted 20 Apr 2015 Dear friends, I would like to understand how i can get analog output from cj1w-da08c.you can see my settings below.WhenI try to write 2001(an. output1) nothing happens.I put 4000 decimal to 2001 and the others 2002,2003 etc.is ther anything that ? do wrong.please advice. http://www.yukletr.com/download.php?file=659ab1ae8f909b48980a798aa538503c Share this post Link to post Share on other sites
Posted 21 Apr 2015 I cannot download your document. Zip it and directly attach it to a post.. The most common problem with analog outputs not working is that the output conversion start bits are not set in the user program. Have you turned on CIO bit 2000.00? It's the output conversion start bit for analog output 2001. (2000.01 for 2002, 2000.02 for 2003, etc). If this bit is off you can set a value on the output adress but the output will not do anything. Share this post Link to post Share on other sites
Posted 21 Apr 2015 dear Pdl thanks for reply.I already have done what you said.I use Cx programmer 9.4.I do it using PLC I/O table menu by enabling output channels.I also chack it from PLC,They are all 1,I also move D20000 #FF. What else am I doing wrong? Share this post Link to post Share on other sites
Posted 21 Apr 2015 I should say that I put +24V to A9 and 0V to B9 Share this post Link to post Share on other sites
Posted 21 Apr 2015 If you enable the output channel through IO table and you power cycle the PLC, the bit is set off again. Turn the bit on in your program, e.g. |P_On|-----------(CIO2000.00) +24V to A9 and 0V to B9 is ok, how do you measure on A1/A2? Best is to take off output wiring and put your loop tester directly on the terminals. Share this post Link to post Share on other sites
Posted 21 Apr 2015 I use fluke 179 .I connect it directly to A1-A2. no mAmps. even 4mA is not there.I have done what you said.2000.00 is now 1. Share this post Link to post Share on other sites
Posted 21 Apr 2015 Put PLC in stop, open IO table, select Create from menu, so we are sure the actual settings are in the CXP file. Next post your CXP file. We can have a look. Share this post Link to post Share on other sites
Posted 21 Apr 2015 dear pdl, I solve the problem .It is because the loop tester Now everything is OK Thank you so much for your interest. Best regards Share this post Link to post Share on other sites
