Posted 16 Mar 2007 We are using a S7-300 series PLC and the information we have is that address M0101.1 is the flasher bit for a one second flash. You can, it says, use bits 0-7 with different flash times preset. We tried using the .1 bit and have a one second flashing light for our panel. It didn't work. Anyone know what's up? I am new with Siemens and am having some difficulty adapting my thought process from AB to Siemens. Share this post Link to post Share on other sites
Posted 16 Mar 2007 Hi semilogical, Where does it say this? GS Share this post Link to post Share on other sites
Posted 16 Mar 2007 (edited) I think you are refereing to the Cycle/clock memory function? It depends which byte has been programmed for this function. Go to the hardware configurator, higlight the CPU and right click, then select properties. In the pop up box select "cycle/clock memory". Here you will see what byte has been used, if none the select the box "Clock memory" and enter the byte required. Bit 0=0.1sec 1=0.2sec 2=0.4sec 3=0.5sec 4=0.8sec 5=1.0sec 6=1.6sec 7=2.0sec regards Edited 16 Mar 2007 by Moggie Share this post Link to post Share on other sites
Posted 16 Mar 2007 Hi moggie, Thanks for that info' - I didn't know about this functionality. I just tried it on my 315. It didn't work at first because I didn't download the modified hardware configuration. Maybe this is semilogicals' problem. Share this post Link to post Share on other sites
Posted 19 Mar 2007 It might be, we will have to wait until system checkout before we can try it. The unit was removed from my desk for panel assembly. I'll let you know if the old guy doesn't forget to. Share this post Link to post Share on other sites
