Hi, I need your help. I've been tasked to backup a program from a running PLC 90-30. Is it possible to do so without having the original project? (like you do with Siemens PLC?) We bought the cable IC690ACC901 and want to backup the running program to our PC, in order to have a copy of it, but I couldn't find an option in Profivy Machine Edition to do so. Should I make a new empty project? Thank You for your patience.

How to work with special registers in a LCPU L0 structured project on GX Works2
Igor Lasmar posted a topic in Mitsubishi
Hello there, This is my first time here on this forum and also my first time working with this software and PLC. I am working off-line (since my PLC did not arrive yet) on GX Works 2, in a structured project type, with LCPU series and L02 type. the problem is that when trying to use any of the special registers (m8000, r23500, etc...) on my code after compile the error F1028 pops-up, on the other hand the same code with special register will work just fine in a simple project type without labels and I dont know how to make it work on my structured project with labels. -
Hello evreryone! I want to build a Gx Work program.  The condition for auto start is when a low limit sensor is detected.  When the high limit sensor is detected, supply to the tank is stopped.         The order in which the tanks are opened is 4,3,2,1.   Tank closing order is reversed.     Valve 5 must be closed when liquid is being supplied to the tank.  The completion of supply to the tank is confirmed by the high limit sensor. I use MOV transfer e.x D0 K1 Y01 MOV K2 D0       Y2       Y3 I want to open coli Y1 Y2 Y3 every valve how to open toether. Thank you       Â

When we simulate a plc program we have to manually input the changes in input(like magnetic reed switch) For example when a cylinder goes from up to down reed turn OFF and reed down turns ON Is there any program available where we can define such things that will turn on and off during the process automatically.

I am not sure if anyone know any websites or sources ,to practice and program same as real projects. I have seen many websites but they are not realistic.

I'm new to this forum, and hope for help. We have a woodworking edgebanding machine (Cehisa, made in Spain) that stopped resetting (starting), a tech diagnosed a bad PLC because all its led's were flashing. Cehisa owns the software, so they are only source to upload the project. They quoted us $7500.00 + $100 shipping for a replacement (!!!). Problem is, even if we paid this , the replacement could also fail if it's an internal or external component problem. Siemens tech suggested a power supply issue possibly. ( I put PLC in Stop, disconnected all outputs and lights stopped flashing. Can anyone suggest steps to meter test & "possibly" save the one we have? Spain, our US distributor, and our tech stopped communicating (they all say buying the new one is the answer). I have some electronics background, have and understand our machine's schematics but not versed on PLC's. Sorry for long-winded text.

Display PLC Time on HMI and Comparing Entered HMI Time to PLC Time
Link068 posted a topic in CX-Programmer
Good Afternoon, I am wanting to do two things with and ORMON PLC and HMI with CX-Programmer and NB-Designer. 1. I want to display the current time from PLC on HMI with the real time clock. 2. I want to be able to enter a time on the HMI which will be compared to the PLC time and will stop a process when when the entered time is equal to the actual PLC time. If I can have some help with this that would be a great help. Thanks, -
Now I working on omron CP1H PLC, i'm receiving ASCII number from another PLC which is something like this "#3031 #3030 #3030 #3030" which mean 01000000. How to convert the ascii number to real number or bcd without separate them? I know how to convert them which is using HEX but its turn out the number will separate into this 0100 and 0000.

Hi, I am trying to convert a variable of REAL data type to DWORD. I 've tried using Real_To_Dword function which works fine if the real number is integer but when the real is decimal the function rounds the decimal number to INT first (I ve also read it in the instruction manual so no surprise here). I 've also tried experimenting with the function CopyRealToDWORD but again the outcome was not what I expected. Is there another way to convert decimal real numbers to DWORD without losing the decimal portion?

I have a function that reads ASCII code from a transducer, converts the code into characters and places the characters from the serial buffer into a string. Now, I am trying to convert the value in the string into a 64-bit float number. Any ideas on how to do that on the CCW?Â

Hi Gents, Is it just me or it's generally that difficult to get the specifications in the industry? I kind of smile at some emails nowadays but here are some fundamental specification issues which felt like I had to go through on many projects through clients client: - New analogue/digital instruments installed with rated voltage of 110V AC while control is fully running at 24V DC - Request to Install TIA portal V15 on Windows XP (as they had all their legacy code on) so the client could have every software on 1 PC (no VMs) - Transfer signals from new PLC to the older PLC - no specifications on literally anything related to the requirements - Travel 500 miles extra as customer wants an extra signals in the PLC (cuz he forgot to mention them on site) Do you ever come across situations like this or am I simply over dramatic?

Hello. I'm having difficulties of how to write REAL constant in ST. For example (Gap1 is defined as REAL): Gap1:= UDINT_TO_REAL(P_Cycle_Time_Value) / +1000.0;   RETURNS ERROR ERROR:  Conversion cannot convert from Integer Literal to REAL I have also tried 1000.0 If I use: Gap1:= UDINT_TO_REAL(P_Cycle_Time_Value) / INT_TO_REAL(1000); COMPILES OK My question.. How do I write REAL constant in Structure text? I don't want to use INT_TO_REAL anytime I want to do calculations with constants.. Thanks. BR.

I'm fairly new to Mitsubishi and I am trying to limit the amount of decimal places of a real value down to 3. I am using a FX3U CPU and the only thing I see in the manual is that real values are stored with approximately 7 significant figures. Is there a way to limit the amount of figures after the decimal point to 3 without converting to an int value? Also does restricting the decimal to 3 points on GT works change to PLC value at all?

Hi everyone! I have a question to all of you guys - do you ever use any software or online tools to manage your automation/electrical engineering projects? I have worked in a number of companies and have seen various scenarios, from using excel tables to run multi-million dollar projects to using proprietary SW for every little tiny project. Unfortunately I do not have experience working for any major big integrator and am very curious how projects are managed at this level (and if every engineer likes the way it is handled). Additional question - does anyone have ever used a software to automatically generate the PLC code? I know some companies develop products to generate the "skeleton" of PLC program and I think it is a great thing to have.

I am new at PLC programming, I have tried some ways to convert a text into DINT and I haven't found the right way yet, maybe somebody can help me. I want to convert "Hello" to DINT, for example. I tried converting it on here https://www.branah.com/ascii-converter  to decimal and then using it as an input for a ROUND, FLOOR, TRUNC blocks to get a DINT, but when I get the result and use as an input in a DI_R i block the output doesn't match with the first conversion of "Hello". Any tips on how do I get it to work, please? Thanks in advance.Â

Good day everyone. Somebody can help me to to resolve the issues in our PLC. I am not a PLC engineer, your help will be highly appreciated. It is showing - Failed to open the Project file. Possible causes: 1.The data in the project file is completely damaged; 2.The data is created by new version more than this S/W; 3.The project file does not exist. Hopefully, somebody can help me or give instruction on how to check those possible causes.  Thank you.

There have been many good discussions on the applicability of cloud-based solutions for manufacturing and process control systems. On one side, some people have concerns regarding security and control of the information, on the other side, there are identified benefits enabled by cloud systems. From VMS minicomputers to DOS and Windows, from ArcNet to Ethernet, it is inevitable the industrial automation systems shall adopt the technologies that are getting predominant in IT general use; the current environment that I am calling the “Cloud-iPad era” is no different; therefore the practical discussion is not if those new technologies will be applied in the industrial environment, but how. This paper is not intended to join the conceptual discussion about the cloud, but just to present a few simple practical examples, where cloud technologies are already enhancing industrial automation solutions and enabling new business opportunities.

Hello - I am currently setting up a program to control a downlane conveyor motor and ran into the issue of operators leaving the conveyor on through their breaks/at the end of the shift.... I know, shocking . Anyways, the essentials of the program are the following - ladder logic, start/stop PB station, a sensor that says when I've seen a box for x-amount of time I will turn off, when the eye is clear for x-amount of time I will turn back on. When trying to 'solve the problem' of the operators leaving them on, I figured this would give me a chance to use a RTC (real time counter) and program it so that at various times of the day I will send a single shot to verify the relay is CT is open. I've enabled the RTC on the Micro810, dropped a TOW but do not really understand how to set the TOW block up. Hopefully that all makes sense. Thanks, grubb

Hello, I am having an issue with FIX Dynamics Real Time Database and the database columns available within when trying to query the database. On a system running iFIX 5.0, there are 19 data columns available, LHS of attached screenshot (in the screenshot example, crystal reports is used to view the columns). However in iFIX 5.9, only 15 columns are available (RHS of attached screenshot ), how can these missing columns be made available to be accessed? Regards, John
