In my present project, I have to interface an energy meter that has its kWh count in 64 bit Double format. Now that Vijeo citect hasn't a facility to create tags of the "double' type I am looking for a work-around to this problem. Thanks for any help/advise in this matter

PowerFlex 525 overwrite my parameters/ Spd + Strt Problem
charonsk posted a topic in Allen Bradley / Rockwell Automation
Good day, I´m helping with small project and currently i am stuck because of this problem. And I hope you can help me out. I´m using PowerFlex 525 connected with AB CompactLogix 1769-33ER PLC via EtherNet/IP. Connection is working, I can read and write values from/to 525. To configure both devices i´m using RSLogix 5000. 1) First problem occurs after I loaded configuration to 525 and it´s, that 525 keeps overwriting values of Accel and Decel Time 1. It happens when i directly change parameters in Module Properties (online) or after I upload configuration to device. It happens even if i set parameters directly to 525 with its HMI panel. - I kinda get around this problem when i use Accel/Decel Time 2 for Step logic, but if i send direct reference value motor still jump to it and that is not good, especially when changing direction of rotation. 2) Second problem is that I cant get Speed Sources and Start References right. Usually Is working only option 1 and others are not, or they are doing something else that they should. For better imagination this is what i want to do: I have 3-state switch (left = 1 ON(DigIn TrmBlk 02), 2 OFF; center = 1 OFF, 2 OFF; right = 1 OFF, 2 ON(DigIn TrmBlk 03)), In center position I want to control 525 with EtherNet (already working when: Start 1 AND Speed 1 = EtherNet/IP). In left position I want to control motor directly with Drive Pot and In left position a want to start Step Logic (which i have already set) - Funny thing, If I set Start 1 = Ethernet, Speed 1 = Step, Start 2,3 = DigIn, Speed 2,3 = Drive Pot then in all three position motor goes in Step logic.. Or when i get left and right position working then Ethernet is blocked.. and this kind of things.. I Attach print-screen of my current settings, if you need something more just, tell me. Thank you for your time, and I hope someone will be able to help me.- 1 reply

Turning inches traveled per pulse (a real number) to inches per minute
487mcgill posted a topic in Allen Bradley / Rockwell Automation
I am currently trying to get my program to take distance traveled per pulse, which is based off of the diameter, and convert it into IPM. I am using RS Logic 5000 software. If anyone could help me get over this hump I would really appreciate it! -
Updating PanelView C600 Clock from Micro850
bainsteven posted a topic in Allen Bradley / Rockwell Automation
Hiya Guys, New here (first post!) - and I'm fairly new to Connected Components Workbench, so apologies for the mammoth post! I am currently developing a System using one Micro850 PLC and one PanelView C600 HMI. I am able to update the current HMI time by sending Unsigned-Integers to Global Connection Tags: System Clock – Hour ($SysClockHour);System Clock – Minute ($SysClockMinute);System Clock – Second ($SysClockSecond);However, if using the same “update time” more than once, this method does not work as the HMI is looking for a “change” in a Tag before an update occurs (Tag-specific). For example, we require to be able to receive a “synchronisation signal” on a digital-input on the PLC each day at 15:00:00. This will only work once as, even though the HMI’s current time updates every second, I will still be sending the values “15”, “0”, and “0” to the above Tags (which will therefore not force an update – as they haven’t changed). I cannot reset these Tags without updating the current Time – as any number “out of range” causes an error (incidentally the errors are shown on the HMI to occur on Tags “SysClockSecondTimed”, “SysClockMinuteTimed”, and “SysClockHour” – note the omission of the word “Timed” on the Hours error…). There appears to be no reference to these “Timed” Tags anywhere in CCW, and I have no idea why the “Hour” update errors on a different (the correct?!) Tag. It’s a pretty confusing problem and difficult to explain… it took me a while to get my head around it – and I can see what the code is doing! J I've looked for documentation on how these Global Connection Tags work, but I can't find anything. Everything I (think I) know so far is from extensive testing... so if anyone knows of any documentation, or has any suggestions as to how I can achieve the required result - that would be massively helpful! Thanks for taking the time to read all this! Cheers, Steve. -
Can any one help? I am trying to write logic to collect data off a Control Logic controler using V.20.03 Logix5000 software. Attached is a copy of Time and Date logic. I there an easier way?

Hello all, I am experiencing an unusual (and what appears to be an unheard of) behavior in my CompactLogix L18ER controller. I am setting the date/time of the controller from my work station, however when I GSV WallClockTime, it is reporting 4 hours different. I have asked our local resources as well as done some forum and knowledgebase searching without result. Has anyone encountered this before? Attached is a screenshot of the controller time vs. the wall clock time. This isn't mission critical since it can be manually adjusted however I would like to understand what is taking place that would cause this behavior. Thanks!

Hey guys, sorry for all of the newbie questions, I had 1-2 years of PLC training at a tech school, and then I got a job where I didn't use my knowledge at all for 2 years, and now my current job is all PLCs, and I have forgotten some of the stuff I learned, but it's coming back to me, so I appreciate all the help with the stupid questions. Anyways, here is my question. I am using a MicroLogix 1100 running RSLogix 500 to collect data on a few of our machines about scrap parts and run time vs down time. I just have some basic inputs hooked up to it. I need to be able to send the data to an integer file at the end of every shift, and then reset the current data (easy enough for me, at a certain time I will use a MOV function to move the info from the timers and counters to integers and then use a RES function to reset everything that I want). Anyways, my question is how to I tap into the free running clock built into the MicroLogix 1100? I see that it is S2:4, but I am confused how to use it or set it. I just set one up on a SLC 5/05 and that was super easy, I just set the time while it was online, and then used 3 different COMPARE functions to tell it when I wanted to move/reset the data (I used S:40, S:41 and S:42). Anyways, I can't seem to figure out how to tap into this clock on the MicroLogix 1100. Can anyone help me with a "dumbed down" step-by-step guide. I just want data sent at 6:30, 14:30 and 22:30 and then data reset 2 seconds after each of those times. Any help is truly and honestly appreciated and very useful. Thank you in advanced. Howard
