  1. Panasonic FP0 C14RS

    esso1972 posted a topic in Other PLCs

    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
  2. 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?

  3. ZCP Instruction

    mr_electrician posted a topic in CX-Programmer

    Hi group! I am struggling to figure out what I am doing with the Limit instruction (ZCP 088).  I want to turn on a permissive if the compared word is between 1 and 12.  Rockwell makes this so much easier!!! It looks like my "=" instruction is not correct but this is how they show it in the manual???????    

  4. Modbus Addressing in Weintek HMI

    rohandarji posted a topic in HMI & SCADA

    Modbus addressing in Weintek HMI to poll data from Temperature sensor through RS485. In my system i have connected Temperature sensor to I/O Scanner has output in terms of RS-485 which directly connected to COM3 Port pin. No. 6 (as Negative) & 9 (as Positive) of HMI (Model No: MT8071iE) and HMI connected to PC via ETHERNET. I want to read temp on HMI screen via MODBUS protocol. So, can you please provide me instruction about addressing of MODBUS register in Easy-Builder Software so can read data of corresponding register. Because when i do compile i got an error like " Device no Response". I hope i will get reply from your side as Fast as possible to overcome this problem. Thank you.

    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?

  7. 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...
  8. Hello. How can I get bit addressing of defined variable in function block? For example: - I define variable type DUINT with name Double_VarI_INT. - I want to get or set one bit out of it (its double word). - If I use Double_VarI_INT.0 I got error. Best regards.

  9. Double address - Alarm

    Extraday posted a topic in Mitsubishi

    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,...)

    electric101 posted a topic in Siemens

    Hi,  I'm attempting to convert some old Siemens workshop 505 code to control logix and i have basically no siemens experience at all and i'm confused as to how to tell what actual output card X1 or X2085 is referencing??   same with inputs.   
  11. Hello all, i'm looking at installing a completely new network for our PLC system, using a ring topology. at the same time i would like to incorporate the IP cameras and VOIP into the same network.  each system is on a different sub net, PLC = x.x.1.x, Cameras= x.x.2.x, VOIP= x.x.3.x estimated camera traffic will be 25 Mbps, PLC 10 Mbps, VOIP no more than 1 Mbps  switches would be capable of 100 Mbps  question: managed or un-managed switches? if it is possible to use un-managed without affecting operations then this would be a massive cost saving    please only comment if you have practical experience implementing this  many thanks Dan  
  12. 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
  13. 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?
  14. Hi, I was wondering if there is a way to limit the number of allowed on-line connections at a time to a PLC? Like can you somehow set in the PLC parameters that only 1 'connection' can be on-line in the device at a time? Thanks Edit: I'm referring to connections from the TIA portal - not HMI / ethernet connections and so forth
  15. 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.
  16. Hi, Iam new to schneider electric PLC drive programming and also to canOpen communication. I have an LMC058 PLC and there are three Lexium 32A drives connected via canOpen which inturn controls three servomotors. My question is how to find/ read hardware limit status of the axis in which limit is connected to a digital input pin of the drive. Even though the axis is properly working by configuring the digital input pins we are unable to get the digital input status of the drive. In the drive manual its given that the digital input status can be read from canOpen address 3008:F(hex) we dont know how to read the status during run time in the program . Can any one advise me how to read that address. I tried SDO_read function but its giving me error(canOpen network id Unknown). Thanks in advance.
  17. Hello. I'm trying to use index addressing inside function block.  The command *D200 doesn't work. Is it necessary to use IR0, ID0,... inside function block? Thanks. Best regards
  18. 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.
  19. Long ago i remember finding a way to change the online step number limit, which is defaulted to 500.  But it was probably 15 years ago, and i have forgotten how i did it.   Has anyone else found a way to change this?
