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...

Hello all,
I am looking to write an HMI in VB6. This code will read/write bit data from a Siemens 222. This is for a test station, nothing fancy... I have done this for AB SLC's, but never Siemens. Is it even possible? Any links to source code or drivers is appreciated!
Thanks in advance.
I am working on a project for transmitting line faults/errors to a marquee. The line controller is an AB control logix, and the marquee is owned by an independant "watch dog" system. In the past, we've used text messaging over Profibus. Logic in the PLC will pass a code to the HMI. This code is...

Hello,
I am currently creating a SCADA system. Part of the program will read from the timer registers of a PLC. Since the PLC Timer acc and pre values are in seconds, I need to write some code that will display a HR:MIN value in a txtBox. The operator shouldn't have to try to figure out how...

Hello,
I am fairly new to the PLC game. My primary background is in mechanical maintenance, but with technology comes computer controls. I went back to school to get the competitive edge. There I learned the basics for the AB SLC family. I have been working with the AB products for a while...
