  1. Hi, I have a system which was not used for few years and now planning to use it/commission it. It is a Control logix platform, 1756-L61 ControlLogix 5561 rev 13.25. The battery fault is ON . As per AB literature 1756-L61 SERIES "A" should use battery 1756-BA1 and SERIES "B" should use battery 1756-BA2 if not then CPU could be affected. Could anyone pls advise how to find out the series of a CPU, i could find only the above information from controller properties. Thanks
  2. Can anyone advise if there are data structure #s associated with each of the data types in Logix?  Example if it is a Bool, I believe Logix advises it is a 32 bit number.  But is there an "under the hood" data type reference number for each Logix data type?  I.E.  if it is a Bool, that is a RA data type #1, if it is a DINT, it is a RA data type #2, etc.  
  3. I forgot how to do this. If I put in let's say 1234569632<cr><lf> how do I store the carriage return line feed along with the number in my ST file??? 1234569632(chr$13)(chr$10) something like this, but can't remember. Thanks
  4. Hello! I'm working on a project. I cannot get online with the PLC. The compagnie who made the program does not exist anymore so they cannot help me. Does anyone knows how to unlock a locked controller ? Do you know a compagnie who can solve this kind of problem ? Otherwise my only option is to wipe the all thing and reprogram it .... which would be bad. Thanks !
  5. Hello, my question today deals with a particular way of coding in RS Logix 5000. I have two routines ( titled "Gauge" and "Alarm"). where rung 10 in Gauge is the exact same as rung 2 in Alarm. How can I make a change to rung 10 in Gauge and allow the program to automatically make that same change in rung 2 of Alarm? The only reason these two routines have the same rung at 10 and 2 respectively is to make trouble shooting easier whenever an issue arises. So instead of searching through the "Gauge' routine to find out where the fault is, I can easily look at the "Alarm" routine and find out what the problem is. I just want to be able to make changes to the Gauge routine and find someway to allow the program to automatically update the exact same rung in the Alarm Routine. Thanks.
  6. 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.
  7. Automation professionals, I would like to read the display values of a red lion DP700 in a control logix PLC. I was able to successfully integrate both devices through EtherNet / IP and I am geting the corresponding values in a DINT register in the PLC. But the problem is that the value in the PLC register is not in the same format as in the DP700 display. The display reads the length of a product in inches like 288.484 etc. Where as the value in the register is a 10 digit number like 1133526516. For sure, there is a definite correlation between these two values but I am not able to figure out the exact relationship as a function of a formula. I have given below 25 data pairs for your analysis. I tried to find out the scaling factor (slope and offset). The scaling that I found fit the first 10 records but did not fit the remaining 15 records Can you help me to find out the relationship between the ? # DP700 PLC register 1 288484 1133526516 2 288627 1133531202 3 288631 1133531333 4 288739 1133534872 5 288741 1133534937 6 288742 1133534970 7 288746 1133535101 8 288757 1133535461 9 288776 1133536084 10 288796 1133536739 11 241060 1131482972 12 241043 1131481858 13 241027 1131480809 14 241032 1131481137 15 241055 1131482644 16 241038 1131481530 17 241078 1131484152 18 241025 1131480678 19 241030 1131481006 20 241037 1131481465 21 241040 1131481661 22 241023 1131480547 23 241053 1131482513 24 241041 1131481727 25 241077 1131484086

    Dear Friends, In my present project, I have a S7-1500 PLC & 3 Nos, Sinamics VFDs(PM-240s) with Profinet ports.(CU-240E -2PN) The drives and PLCs are on the same Profinet network. I wish to know the essentials of controlling the command and speed reference of these drives directly from the PLC on profinet. Reading the help in TIA portal got me nowhere its all about Telegrams and things that I haven't figured out yet Thanks for looking in; I shall greatly value all help and advice.
  9. B&R plc, motion control, CNC

    Hi all. I have a B&R PP420 panel, some I/O on the X2X and 4 Acopos servodrives /servomotors. Successfully created and tested 4 axes, they work OK, control via NCtest or X2X IN, or PP420 display. But creating CNC system is the problem... On NCtest, I have errors, and no move. Error 7742: ACP10_MC FB error or aborted Info: Axis Index [0] Info: ACP10_MC FB error number [29226] Info: Command aborted [0] Info: ACP10_MC FB number [1] = MC_BR_MoveCyclicPosition (cyc. pos.)

  10. CJ1W-TC001 PID question

    What is Omron naming convention for PID settings? I need to adjust the upper MV limits for PID running on CJ1W-TC001 installed on CJ1M-CPU13. Looking at the CJ1W-TC001 Operation Manual I am not really sure which values would these be. I guess Omron naming nomenclature is a bit different than what I am used to. It seems that the Manipulated Value Monitor is just feedback, which value would I need to set or modify to adjust the upper MV limit?
  11. Currently we have a remote I/O module to connect with our PLC, yet it's not showing up whenever we try to connect it via inside RS logix 5000.
  12. Hello All, I want to read data from a Control Logix PLC, into a PLC5/60, using Ethernet and a MSG instruction in the PLC5. When verifying the MSG instruction in the PLC5, I get an error message. "Target Address in invalid". Once I figure out how to do this I need to replicate it in another PLC5. Scope is to read the status of 4 paint pumps controlled by the CLX. If any of the 4 stop, the PLC5 needs to know, because it is controlling the paint application equipment. Source data resides in a Control Logix 1756-L63. The tag is INT type, 4 elements long, and the name is PUMP_STS_B2. The IP address of the CLX is 4.2.6.230. There are 2 ENBT cards, one in slot 1, and the other in slot 3. 4.2.6.230 is slot 3. PLC2,5 / SLC Mapping has been created in the CLX. File=421 Name PUMP_STS_B1 and File=422 Name Pump_STS_B2. The file mappings represent a binary file created in each of the PLC5's B421:0~4 in Booth 1, and B422:0~4 in Booth 2. The PLC5/60 is Enhanced series E model using the Ethernet side card. The IP address of the PLC5 is 3.26.5.61. I also created MG file types in each of the PLC5/60. MG420:0~19 in each processor. This was necessary to use the MSG instruction in the PLC5. I have searched the forums for examples of how to do this with no solid results. I am trying to follow the best practices of reading the data into my PLC so anyone who follows can tell where it is coming from. While the IP addresses are not closely related they should be able to communicate. I say this because all of our PC's are on the 4.2.6.XXX network on a 255.255.252.0 sub net and we have no issue communicating with the 3.26.5.61 IP address. Any help and advice would be greatly appreciated. Regards, Mike Carter
  13. I'm having a bit of difficulty with the MSG function on a logix5000. I'm simply trying to get a REAL value ("BH5_Flow") out of another logix5000 and assign it to a tag in the PLC. I've created a MSG function and created a new tag "BH_5_Flow_MSG" for the message, and created "BH5_Flow_M" for the value that will come from the MSG function. When I click the "..." button to bring up the config, I put the following in: Message Type: CIP Data Table ReadSource Element: BH5_FLOWNumber Of Elements: 1Destination Element: BH5_FLOW_MIn the PATH tab, i then put the following in: Path: LocalENB, 2, [iP ADDRESS OF SOURCE MACHINE]When I test the edits, I then get the ERR bit activate with error 16#0004 when the message rung runs. Anyone got any ideas where Im going wrong? I've practically copied another MSG instruction from further up the ladder but it doesn't seem to work
  14. Hello guys, i would like to know if is possible keep always active the run command in a vf drive and for stopping the motor only send 0 reference. It´s possible??? because I want to program a ramp function in my plc for start and stop one motor. could someone tell me how to do this type of control please?.
  15. Hi, we have a system that has multiple cabinets using guardlogix point I/O. For some reason that I cannot explain as of yet we sometimes loose ownership on one of the cards and have to reset it. Has anyone experienced this before and if so what was the cause and solution?
  16. Hi, I have a problem with my BC9020 and hope that someone can help me. I managed to set the IP adress of my PLC in the 10.2.5... add a root, run a program and make the PLC working for a while. I then tried another program, a new one... and now that I want to re-read the first program, Twincat System Manager doesn't allow me to enter in the "run mode" and stays in "config mode". It also has lost the IP address I set (10.2.5.....) and came back to the 172.16.22... (manufacturer settings) I cannot determine if the problem is in the PLC Control or In System Manager... This is my method to change the IP *** IP config *** 1) Reset the PLC First I place the end terminal next to the PLC. I set the DIP switches 1,6,7 to ON, power on the PLC and power off. I set the DIP switches 2,6,7 to ON, power on the PLC and power off. I set the DIP switches 1,2,6,7 to ON, power on the PLC and power off. 2) Set my PLC on the same AMS than my own IP (172.16.22...1.1) 3) In System Manager, add a new route 4) change the setting in I/O Configuration -> I/O Device -> Device 2(BX9000) -> clic on BX9000 define "set IP Address" to Manual define " IP Address" to 10.2.5...., the AMS change automatically. Press the configuration button and then Ctrl+F4 (run mode) This method worked but seems not to be the best... If you have any Ideas ? or questions? Thank you in advance Gregi
  17. I need to change the IP address of an existing PLC. Only access I have is remote (VPN). Is there any issue with downloading the same program - with the IP address changed - to the existing processor? Then change the local network range to match, etc...
