Posted 19 Nov 2019 (edited) Hi, I'm using a CJ2M CPU 33, and also a CJ1m Ad-041-V1 Analog Input and DA-041 Analog Output card. I am using the Analog input to measure my current in my one heating application and Ihave that reading and scaled correctly, but now I want to use my Analog output to replace the Rheostat we have in the system. I'm having some issues setting the range and getting voltage to vary. I also am a little new to Analog Outputs and don't know what I'm doing wrong. I have attached my program here. Any help would be greatly appreciated. Analog Heat.cxp Edited 19 Nov 2019 by Megoof Share this post Link to post Share on other sites
Posted 20 Nov 2019 (edited) Hi You need to start the card 2020.0 , 1, 2, 3 one bit pr channel. Sorry my mistake you have already started the card, but the address for writing is 2021 unit no.2 ch.1 Banker Edited 20 Nov 2019 by banker Share this post Link to post Share on other sites
Posted 20 Nov 2019 I see, but what about getting my voltage to output at say, 5 Volts? I can't get that to show up. Share this post Link to post Share on other sites
Posted 20 Nov 2019 The resolution of the DA041 is 4000. Have you tried to move a static value into D20201? To get 5V, try MOV'ing &2000 or (#07D0) into D20201. After that, then you may troubleshoot the wiring. Also, when changing any settings to the Unit Setup, be sure to cycle the power to the PLC. This is a 'gotcha' for many people, including the veterans of this sport. Share this post Link to post Share on other sites
