Posted 4 Oct 2009 Hi Guys, I am using a CJ1M-13 PLC with Ethernet & D-Net modules. I've pretty well completed my PLC programming (I think) and I'm now working on the majority of my HMI screens. I have a NP5 HMI screen. The problem I noticed is that when I gave access to edit the timer values over the HMI weird things started to occur. I am storing value for TIM #1 in memory address D001. Depending on the number entered on the HMI, sometimes you get an error value inputed even though looks great! It appears that the TIM stores data as BCD and i'm wondering if the HMI is in HEX??? Any thoughts would be great! Scott Share this post Link to post Share on other sites
Posted 4 Oct 2009 (edited) In NP-Designer, you can specify if you use BCD or hex format Edited 5 Oct 2009 by pfort Share this post Link to post Share on other sites
Posted 5 Oct 2009 You can also change all your timers and counters to decimal instead of BCD in the PLC. Better to do this as if you enter decimal from the screen you will have to put limits on entry to 0000-9999. Share this post Link to post Share on other sites
