Hi friends, Can anybody tell me when to use a local-Static variable and when to use a Local Temp variable whilst creating a Function-Block in S7 -1500 using TIA portal. Thanks for looking in. Best wishes.

Hey All, I am trying to do some data storing on a PanelView+ and the built in data logging doesn't quite fit my needs. I was looking into the possibility of creating my own ActiveX control for doing this. Is it possible to create custom ActiveX controls for Factory Talk? If so, are there any tutorials for doing so you recommend? Also, are there any sites that have custom ActiveX controls to download? I realize this may not be the easiest thing to do, but if I could create my own I could use it for various machines and would make things a lot simpler in the long run. Thanks

Hello, I am having troubles configuring my Data Station Plus to be able to read my Vacon VFD registers over a Profibus network. The network is configured from an Omron PLC. I have communication but i do not know how to map the tags on Crimson to be able to read what the drives are doing. I am most likely thinking my offset on the tags that i have set are the main problem. Any input/ suggestion would be great thanks Specs on System: -Omron PLC CJ2M w/profibus PRM21 -Omron HMI NS-12 -3 Vacon NX VFD's -Data Station Plus w/profibus module

Hello all, I am trying to get around a lot of manual inputting by exporting a routine and opening it using excel, but looking at the file that excel shows I have a couple fundamental questions 1. when excel opens it and "creates a schema', can I save this in a format that will allow me to import it back into the program? 2. Since I am mapping data using add on instructions, the table excel has created becomes quote complex, with no clear point of reference to where my Input tags are going to go. We are doing this because someone thought it would be a good idea to put a SCADA based control platform over the top of an AB control system, so we have to exchange thousands of points of data back and forth with their system. I created the mapping AOI blocks to be able to manage the file structure a little better in the routines, but that still leaves me with copy and paste thousands of tags into the AOIs. Has anyone developed a good way to create logic, or modify logic using excel? While I can hold my own with utilizing the RS5000 platform, my excel experience is limited. The processor is a 1756-L75 Thanks

Hiya Guys, New here (first post!) - and I'm fairly new to Connected Components Workbench, so apologies for the mammoth post! I am currently developing a System using one Micro850 PLC and one PanelView C600 HMI. I am able to update the current HMI time by sending Unsigned-Integers to Global Connection Tags: System Clock – Hour ($SysClockHour);System Clock – Minute ($SysClockMinute);System Clock – Second ($SysClockSecond);However, if using the same “update time” more than once, this method does not work as the HMI is looking for a “change” in a Tag before an update occurs (Tag-specific). For example, we require to be able to receive a “synchronisation signal” on a digital-input on the PLC each day at 15:00:00. This will only work once as, even though the HMI’s current time updates every second, I will still be sending the values “15”, “0”, and “0” to the above Tags (which will therefore not force an update – as they haven’t changed). I cannot reset these Tags without updating the current Time – as any number “out of range” causes an error (incidentally the errors are shown on the HMI to occur on Tags “SysClockSecondTimed”, “SysClockMinuteTimed”, and “SysClockHour” – note the omission of the word “Timed” on the Hours error…). There appears to be no reference to these “Timed” Tags anywhere in CCW, and I have no idea why the “Hour” update errors on a different (the correct?!) Tag. It’s a pretty confusing problem and difficult to explain… it took me a while to get my head around it – and I can see what the code is doing! J I've looked for documentation on how these Global Connection Tags work, but I can't find anything. Everything I (think I) know so far is from extensive testing... so if anyone knows of any documentation, or has any suggestions as to how I can achieve the required result - that would be massively helpful! Thanks for taking the time to read all this! Cheers, Steve.

Dear Sir, I want to read data (Digital Input say X0 (Local PLC) and after some additional logic i want write to Y0 (Remote FX3GE PLC on same network) from one Mitsubishi FX3GE and Write to another FX3GE on the same network. Master PLC IP Address 192.168.0.40 Slave PLC IP Address 192.168.0.50 Atif

I am getting this error. How to resolve this?

Hi dear all , i need some helping .. I used CJ2M cpu31, then i want to send data (example D100 = 2000) to PC ...essentially i want send value 2000 to my PC.. wherein the PC and PLC conect via internet IP .. What should tool/software may i used ? Thanks before ..

Hi guys, I've found the following website: http://www.rockwellautomation.com/rockwellautomation_de/news/news-detail.page?reqid=1356918 It shows a download link for some reference material regarding Ethernet/IP communication drivers. I've been lucky with Mitsubishi and Siemens supporting TCP/IP, but for some reason this is just now starting to be supported by Rockwell, and many of the budget controllers do not yet support TCP/IP (at least without an interface module, and even then they are only compatible with certain processors). I would love to write my own Ethernet/IP driver for communicating with Rockwell controllers and I/O blocks. This looks like the perfect starting point as Rockwell claims to support it. I've got an email out to the representative listed in the article, and have talked to rockwell engineers over the phone, but do not yet have any leads. I thought I would post here in case anyone has used this, and could provide some information on where to get the reference material. I imagine there are many tinkerers on here who get excited by these things . I did notice this repository that looks close: https://github.com/EIPStackGroup/OpENer The library is called "OpENer", and the original expired download link in the rockwell press release is "Opener.Sourceforge", so maybe there is a correlation. Maybe this github library is the latest iteration of the project files released in 2009. (The github library looks very reliable, and professionally supported). Any leads on here would be greatly appreciated. If I can prove this concept to work, I will likely go further with odva certification. But for now this will be fun to reverse engineer and prove. Also, if I get any leads on this I will make sure to post back.

I have the following situation; I have a distribution network connecting about 400 RTUs, using 101 protocol to connect to their PDH MUX, which data slot is transported using SDH STM-1/4, to the Primary Substations. Then the primary substations connect to the LDC building using STM-16. At the Control Centre Building where the Front End is located, there is a STM-16 node with some PDH ports, but definetly not 400, so how can I extract this 101 asyncronous data channels to connect them to the SCADA Front End? Note that conversion to 104 is not allowed by the client. Thanks in advance!
