  1. Hello! I have a project where I need to use Allen Bradley PLC, it might be one of CompactLogic series. In scope of the project I need to transfer few real values to DirectLogic PLC that installed on customer side. DirectLogic PLC has installed ethernet card that support Modbus TCP, TCP/IP and UDP/IP protocols as it says on automationdirect website. I start looking for Allen Bradley PLC that support Modbus TCP or TCP/UDP protocol and did find clear information. Could you help me to find out a way how I can pass the data to directlogic PLC from CompactLogic?   Thank you in advance!   Regards, Scotty
  2. Panasonic FP0 C14RS

    Hi All, I am new to the forum and new to programming PLC and like every newbie I have a lot of questions - Brief History of me - I had been a Manufacturing Technician for 20 years and recently got my BS on Electrical Engineering and now working as an Equipment Engineer. The main reason that got me interested in PLC's is my degree,  the field that I would like to get into and a recent problem that arise at work. My experience with PLC is very small in programming, some in TS I/O- However I had been studying by my self to the point that I built a test bench to understand it better and in the future create different project for learning purposes Currently I am putting together a tool Alarm delay program - Basically my exhaust sensors trigger an alarm (input signal turns OFF) before its send  the signal to my tool for abort, I want to create a different Alarm which will cause a different response from my tool and delay the original Alarm by 10 min and then trigger the original Alarm - PLC = Panasonic FP0C14RS  Reasons: Create a different Alarm: The response from my tool to this alarm will allow me to return my material back from the tool and put it in a safe spot. Delay the Alarm: Use a timer to perform this tasks - This the time that approx. it takes the to return the material. Trigger the original Alarm: I need to know which sensor was the problem in order to properly TS- So after my timer is complete - I want to know which sensor created the original Alarm My Current problem: I created the LD program, and while the original alarm stays OFF the program works fine - but since my exhaust sensor are always on - If my original alarm is trigger for  a few seconds, just enough to start my Delay Alarm: I dont have a way to know which sensor trigger after my Delay(Timer)is complete,  I reset my relays in order to be ready for new alarm.   Please provide feedback to my program - I know currently is not the best way or efficient way to do this and there are better ways, but my plan is to get it to work and then later revisions improve the way the program can be written   Thanks in advanced for your feedback and help Exh_delay_inv_rev1.pro
  3. Every time my rsview32 project starts up all the alarms which are set up to alarm on 0 tag value show up on the screen even though the bit in the PLC is not in alarm condition. I believe this is because the communication between RSView32 and PLCs is not established yet and the tags are seen as having value of 0 in the HMI. Is there a way to disable or suppress these tags at startup to give enough time for the RSView to update the values so the false alarms are not being displayed?

    Have looked right through the manual and cannot find anything. Finish up with a scrolling line. Ideally I would like to have an alarm page and alarm history page like the one in the NS screens. Any thoughts please?
  5. CP-1E Error

    Hello,  I am using Omron CP-1E PLC and expansion module 16ER and tc module.  When plc operated alone it goes to run mode when expansion module is connected either 16ER or TC module plc ALM/ERR led turned on.  
  6. Dear masters! Hello! I have a PanelView Plus 1250, firmware 6.1, and I would like to know if it is possible to export to csv or .txt and save the alarm history to an external USB memory from the terminal? Today I'm typing the whole alarm history manually...
  7. Hi..  someone please help me.. i'm working in omron CS1H-H CPU67 PLC. My struggle is I/O in one particular rung is not getting updated.  Note: the rung is consist of a P_On flag followed by a FB ; all I/O to the FB were correctly assigned. but the inputs inside the FB instance are not getting updated so that the output not updated. can anyone please help me....????   sorry for my poor english... thanks in advance.
  8. I need to run 4 exactly same devices with 4 different controllers. The logic for them would be exactly the same but the IPs and controller names would be different. Is there a way to do it using 1 project file? Basically whenever download is done the logic would be downloaded but the controller name/IP would be left unchanged. They will be connected to the same network so the IPs must be different. I am using 1769-L32E for these and all racks are set up exactly the same. Any ideas?
  9. Double address - Alarm

    Hello, I would like to see your logical opinion about this situation and in which part of system where I need to find solution - software or in the physical field. Subject: Twelve old system based on Mitsubishi PLC AnS series, Profibus Here is pneumatic transport, with 5 lines, each line have a shredder and discharge valve. A few months ago, when line 1 works , display shows line 2 and vice versa, it was first problem, but the system was still working. From the last week system doesn't work. On the display appear line 3 in works, but system can not started. Alarm shows Double address (perhaps two valves have some address), Alarm still appear after reset and even all lines are turned off. What is your opinion where to find proble (PLC, I/O moduls, cables,...)  
  10. Hi Everyone, I'm working on my first PLC program and I have gotten my hands on some ladder logic I'm trying to duplicate. I'm using SoMachine 4.1 and have started a new Ladder Logic diagram POU. I'm curious on how do I create internal contacts. EXAMPLE: 24v--------l START BUTTON l----------------( COIL A)----- --------------l COIL A CONTACT 1; attached to a real output, solenoid valvel-------------l COIL A INTERNAL CONTACT TO CLOSE l---------------- Are there standards for numbering and labeling? I'm seeing L and U inside coil contacts. Does this have an underlying meaning according to standard? Is there a RTO function inside SoMachine 4.1    
  11. Hi everyone, I'm a newbie in the ladder logic programming languages. For my thesis project I've to develop a scenario but I'm stuck with the creation of a socket connection from the Modicon M340 PLC to a server for transfer continuous data given from sensors or similar. Does anyone have a sample program that could have such a functionality so that I can change it based on my needs? Thanks in advice for any further reply!
  12. TIA Portal V13- Alarm for Bool Data type

    IN TIA Portal V13 HMI Alarm Setup, Discrete Alarm Not allowing Bool Tags in "Tag Trigger". Please help how to set Bool Alarms?
  13. Hello, I am currently working on programming my first sortation system.  Attached is a blue print of the in feed conveyors and their loadout lines.  As boxes merge together they will be scanned by the barcode scanner.  From there we will be told which lane each box must go down, from the WCS.   My question is, without encoders, what would be the best way to control this system? Counting the packages as they pass through the photoeye? Or setting timers?   Thanks, James Sorting Conveyor Layout.pdf
  14. PLC SIMULATORS (LADDER LOGIC)

    CAN SOMEONE PLEASE SUGGEST ME ONE OF THE BEST ONLINE LADDER LOGIC SIMULATOR OR SIMULATOR SOFTWARE FOR PRACTICING AND DEVELOPING LADDER LOGIC SKILLS.??
  15. Please if anyone can help me, recently I installed a redundancy in my Factory View V8.20 server, but started to show some errors: My alarm banner and event simply disappeared and now I can not read tag from my opc server (KeepServer Modbus), I see this tag in the studio, but at runtime they do not communicate. * Patches are up date. Tks! Vitor
  16. I have entered the messages many times into the Alarm Setup but every time i re-open the alarm setup, every message that has the Trigger Value=1 will be deleted.  Anyone have a similar issue?
  17. Hi, I have some concern regarding sending an email automatically when an alarm trigger(High, Low Level Alarms - Bit), Is this possible for the software?  Thanks for any reply.

  20. Monitor alarm block

    Hi all, I would like to monitor the status of my alarm word (MW100) and if any bit turns from 0 to 1 then an alarm signal should be generated, am new to siemens plc and am having a tough time accomplishing this easily. In omrom CX programmer its quite easy to do. Could anyone help me on this using ladder logic, all help will be deeply appreciated.  Regards, Ablex  PS: I'm using Step 7 V5.5
  21. Hi guys, I'm in the middle of a little university project, I'm attempting to implement a control system purely based on artificial intelligence. A neural network will be used to map the characteristics of a power plant. A fuzzy logic controller will be used instead of the conventional PID and finally a genetic algorithm will be used to tune the controller while the system is online. This is all simulated of course. Each of those AI's will be developed in Matlab. Only problem with that is, is it outputs the code in C or C++ (From memory). I would have to convert this to structured text (Based on Pascal). So to circumvent this problem I thought I would just directly interface matlab to the PLC (Schneiders M340).  My idea being, all the calculations are done in matlab which are then sent back to the PLC. However this presents me with a new problem of how I would be able to interface matlab to the PLC. If anyone has experience with this sort of connectivity, any advice would be greatly appreciated. Thank you in advance, Luchek
  22. 800 Panelview

    I wold like to create an alarm history list that can be scrolled through from most resent to 1st. Is this possible with the Panelview 800 7"? We were able to create a page but it holds only 25 alarms and you can't scroll back.
  23. Hi, I am using syswin and i am doing an exercise on saving and moving data. My challenge is am monitoring temperature from a sensor and the range is -20'C to 100'C from the 4-20mA sensor, after conversion and testing for positive and negative the values are stored in D205. (I have done the conversion and testing for positive and negative values only assigning of bit 15 in D205 is left) The simple program has to turn on Bit 15 if the value is supposed to be negative. 1000 0000 0000 0001, a simple approach to telling us this is -1’C.  0000 0000 0000 0001, is telling us this is 1’C. Bit 15 is going to be our Sign Flag, so we have to ensure that if the temperature is positive then  Bit 15 = 0, how can we do this make Bit 15 of D205 = 0? If the temperature is negative then  Bit 15 = 1, how can we do this make Bit 15 of D205 = 1? How can i turn on this bit inside a data word? for negative i thought i could just add #8000 to the values after conversion then storing in D205 but for positive values how do i ensure that bit 15 is 0? How could you approach this? Am a bit stuck, all thoughts and ideas are much appreciated if possible you could add a snapshot from syswin or cx-programmer. I have attached the WTANK.SWP file which can be opened in syswin or cx-programmer. Look in block Main 8 Temp Buffer, Network 3 Convert to 'C WTANK.SWP
  24.
