Is there an AB part number for just the structured text (ST) addition? I have the one for the multi language pack. I would like just the ST pack if available.

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. -
Most Important Scripting Language For Controls Engineers
OmronOmicron posted a topic in General Topics - The Lounge
As the industry of plc and scada softwares continue to integrate more and more programming languages into their IDE, what is the most common language that should be learned by controls engineers (excluding Ladder Logic)? I mainly use Python and VB for scripting but I am curious what languages other SCADA and PLC programming environments use. Should I be sticking to a specific language and learning it well or just know a little bit of them all? Let me know your thoughts!! -

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

I need to program a Phoenix Contact PLC in Structured Text. The PLC should communicate with a motor that uses the CANOpen protocol. The only resource I have is the dbc file. I'm kinda lost about where to start. If you have some suggestions/recommendations I would appreciate it. Unfortunately, Phoenix Contact only has a CAN library that is really limited to work with and the complete configuration is done via function blocks that represent the transparent CAN layer (you can't include EDS files or DBC files).

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.

Hello everyone, I am new to PLC programming and will start working on Allen Bradley PLC. I have an experience in computer programming languages. Will learning ladder logic be a better option or starting with structured text as i have some knowledge about the syntax and programming of structured text?

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?

Not getting one-shot inside IF...THEN
Joseph 0028 posted a topic in Allen Bradley / Rockwell Automation
Hello Folks... The pictures show it all... I just need to produce a one-shot inside the IF...THEN, and the Oneshot's input bit goes from 0 to 1 as you see from the trend, but the output bit is not going to 1, or giving a pulse ? can anyone help me understand why i am not getting a pulse in this code ? And is there another easy way to get pulse inside IF...THEN without changing the condition which activates the if loop ? Thanks in advance for your time -
Hi all i've been trying to make a simple timer in structured text which is turned on and off by a single input, all instances of flip flops i have found seem to be 2 input. any help or examples would be appreciated example of programs; Pulse signal received, start timer Pulse signal received stop timer

Hello group. I am practicing ST programming and am doing this by converting an existing Ladder Logic program into Structured Text. I have created the following attachment and I can see my BOOL objects change state when I touch the respective buttons on my HMI. The issue I am having is the Accumulating Timer will not start timing when the conditions are met. Can someone with experience in ST advise me what I am missing or doing wrong. Thanks

I'm working on simple structured text program which takes in DWORD values, does some math on them and then outputs in DWORD type. What data type should I be using and how can I make this work? This is one of the lines from the code(everything DWORD) and I get 'operator not supported by DWORD data type' XPos3 := XPos1 + (2*XIncrement);

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.

Hi, I can’t find an answer to the following and I was advised to ask it here.I’m programming an Omron CJ2M with an MD212 high speed I/O card. I usually do all my programming in Structured text, simply because I like it a lot over ladder or sft.Now, if I want to read the hight speed counter (incremental encoder), I have to make a ladder section and use the PRV instruction to store the present value in a chosen location.The manual says the current PV is stored in A271, but I can’t get a readout there. Apparently the only way to read it is through this instruction.Does anyone know if there is an equivalent to the PRV instruction for Structured text? or another way perhaps? Again, when I check the actual memory adress, there’s no value there withouth the use of the PRV instr.

I am new with PLC's and I am learning how to work with GX Works 2. I have two questions, 1st Question: Using a Q series PLC (Q03UDVCPU) Is it possible to convert the language of a project from ladder logic to structured text? 2nd Question: If I read a project from a PLC why is it always ladder logic? Is there any way to read out structured text?
