    Big Challange... Looking for advice and/or helpful software suggestions

    It is not quite what I designed it for, but you can do something like you want with ControlDraw, and I have myself. You can import (by copy and paste special) pictures to diagrams making an object containing the picture, add text, connections etc. One file can contain hundreds of the diagrams...

    Simple code in Access

    You don't need to use VBA or to have another field, you can do it all in one query. The 5th column would be an expression that reads the other fields, using an IIF (I think) statement Francis www.controldraw.co.uk www.s88control.blogspot.com

    Analog input channel settings based on transmitter response time

    williamlove I said before " Your transmitter may be able to respond in 250mS but if the process is slow (such as the temperature in a large tank) there is no point in sampling that fast." Sampling your input faster than needed just wastes processor time. Executing your PID too fast can, for...

    Analog input channel settings based on transmitter response time

    The first question is how fast the process variable can change. Your transmitter may be able to respond in 250mS but if the process is slow (such as the temperature in a large tank) there is no point in sampling that fast. It is the Process not your instrument that matters, provided the...

    Depicting PLC control on Process Flow Diagrams

    You cannot squeeze it all onto a P&ID either, create separate diagrams and put a cross reference to them on the P&ID. Or use ControlDraw and add the PLC logic as linked diagrams. Francis www.controldraw.co.uk www.s88control.blogspot.com

    PID BLOCK sampling time on AB PLC

    How are you triggering the PID? It should be run at a fixed sample rate that is not too fast but fast enough. Typically you should sample 5 to 10 times the process time constant. See this for example Francis www.controldraw.co.uk www.s88control.blogspot.com

    PLC State Machine Coding

    You may find that this is very relevant Programming Equipment States Efficiently State based control is a method of defining the required states of some equipment and then driving the equipment to one of these states, typically where a Phase step sets the Equipment States.

    VB6 to VB2010 ??

    My VB6 program is quite large and complex, it uses various ocx and dll components and is highly graphical, but I have had few problems getting it working fine in Windows 7, without needing to use xp mode. Converting from VB6 to 2010 is something different and far more challenging. There are...
