    S7-200 PLC's on a PPI network

    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...

    Using VB to create an HMI for Siemens PLC

    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.

    Fault Messaging using Control Logix

    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...
