    Controllogix 1756-L63 Redundancy Type 12 Error

    Speed of change over is fine, the problem occurs when we shut down our sysem as the network switches go down first then the CPU's this kills the redundancy then when you bring the system back up you may or may not get this error depending on which cpu starts first. Usually this error occurs...

    1V p-p sine > TTL signal conversion

    You could use an opamp then schimtt trigger Use the opamp to gain the signal up to 0 - 4.5~5v then run it through a schmitt trigger to square it off this would then become a TTL square wave. Andy

    S7- Soucre Code for Scale Routine

    Can any one help, I'm looking for source code for the generic Scale routine that comes with the S7-300 range of PLC's. Reason being that I want to edit and change it to improve it so that I can calibrate between any two points rather than fixed points. Andy

    We have Cimplicity Plant edition interfaced to Seimens S7-300 PLC through the siemens PCMCIA LINK and an OPC server called Merz. THIS IS BLOODY SLOW. If we take one tag only in Cimplicity (or Merz) we can get it to refresh 5 times a second. If we take 5 points the refresh drops to about just...
