The S7-200 "Micro" is fairly limited... I don't remember seeing any scaling functions in the Micro/Win software; check the online help associated with Micro/Win. There is a lot of good information in there... Personally, any time that I have scaled values, I've done it through the HMI screen...
Hello -
I am trying to create a basic user interface using Visual Basic 6. I would like to use (keep) the original .mdb as my data store. The problem that I have is the Data Form Wizard in VB will not accept (recognize) the .mdb...
Is this due to the original database tables being created...
OK... I did get my CD to work. The problem was with the way I burnt the CD. I needed to burn as an .iso image.
This is what I have for Hard Drive info... The physical HDD is a standard Western Digital 2GB. In the CMOS set up it is set as a user defined type. 1024 cyl, 14 head, 17 sector, 120MB...
Hello all,
I have quite a few older industrial computer consoles that run a unix style OS. The problem is the hard drives are starting to fail. We are looking into replacing the existing hard drives (2 GB) with an IDE compact falsh drive. How can I go about getting the original hard drive...
Hello all,
I have a project that involves integrating several S7-200 CPU's. I have already looked at the help pages in S7 micro/Win. I tried linking an S7-226 to a S7-222 as an experiment, but I didn't get any result. I did use the NET_EXE wizard in micro/Win to configure the NETR and NETW...
Hi everyone.
I was wondering how to annunciate machine faults from a Simatic 216 to a TP270 HMI. I am writing the ladder with Micro-win, and the screen is written with Protool.
I'd like to have one text box on the main screen of the HMI to list machine fault and alarm conditions. I am...
Hi All,
I am looking into a Data Collection project. I'd like to use an S7-300 series PLC with remote IO on Profibus. On the remote IO, I will have several descrete inputs, and thermocouple inputs. What I'd like to do do is write the data logged by the PLC into an MS Database over Ethernet...
A standard RS-232 crossover cable with DB-9's will work.
I have used this approach with 5/03's.

What are the outputs that are being fired? What voltages are you using?
Sure, it is common place to use relays that have their coils energized by the output of a PLC.
For example, you may need to fire a 120 VAC solenoid, but your PLC operates off of 24VDC. Or, you may be interfacing control...
I thought that I'd let you know that I have made my decision. I have accepted the new position. The visit that I had with them went extremely well. It exceeded my expectations.
The new position offers a wide variety of projects, with the addition of project management. This wasn't mentioned in...
