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...

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,

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...
The Long Commute: Relocation was considered. My current employer is located just outside of the suburban metro area, and housing is quite expensive... Secondly, it's a comfort thing - We like where we live.
Pay and Rewards: We just had our reviews. I "scored" well, so I got my "cost of living"...
WOW!!! Quite a good conversation going on here! I will give all of you a bit more info.
