Hello, I am posting a project I have wired in and gone live with but I am having some issues with the pulse count side of the code I have also attached a picture of what I have been trying to achieve. the trolleys are 150mm apart and I am using the trolleys to activate a proximity switch (see picture) I am trying to achieve a shackle count of 75 and as you can see from the picture not every trolley has a shackle attached so I have used the maths block b024 but the returning figure is returning at 125-130 and jumping around quite a bit. Is there a problem with my code or is the logo not capable to carry out this specific task...so help/guidance would be gratefully accepted regards Ade

How often is the proximity switch actuated in one second? |

Try this version. I linked the proximity switch differently. Now only the pulse of the proximity switch is used for time evaluation. But you will never get a 100% absolutly correct Display. There will always be tolerances. Attachmentspeed_m_c_stops_line1_ACM_1_2_V2.zip (241 Downloads) |

hello, I have tested your modified circuit live and is working just fine,because there are 2 lines I was able to use a FS4 logo on 1 line and a standard on the other just to compare the 2's performance. Although the pulse is on average 2 per second, the logo with the fast inputs did show a marked improvement in dealing with the code and conditions. I do have 1 more query how much more change to the current program would be required to tie into the machines start/stop circuit, for example the start signal comes via a key switch spring return this would energise I2 line active and show machine is running.And I4 obviously shows the number of machine stops with flashing amber backlight and shows machine message as stopped. regards Ade Attachmentspeed_m_c_stops_line1_ACM_1_2_V2.zip (223 Downloads) |
