  2. SIMATIC ET 200SP, IM 155-6PN HF problem

    Remove the module and examine the pins on the back, I have seen a bent pin cause similar issues.

    Contactors must have hermetically sealed contacts, or be in purged enclosures.
  4. Has anyone seen this connector before, mfg. website, anything would be greatly appreciated. It is the gray portion shown in the photo. 6 connections wide, 4 deep. thanks, Ken
  5. One OPC server logging to two databases?

    The OPC server should be able to support more than one client. Does your application use the server client arrangement? I have had OPC servers sending data to an HMI and a historian on two different boxes many times. I don't know off hand how many clients the kepware can handle at once. Plus the about of data and the polling time will influence the number of clients also.
  6. Hi Folks, I am looking for a DIN Rail mounted 24VDC fiber switch. I need two multi-mode ports and one single-mode ports all fiber connections are (ST). I was using an Elinx from B&B Electronics, model EIR203-2MT-ST, but they have been discontinued. Can anyone point me to another brand? I have a request in to N-tron, but haven't heard anything yet. thanks, Ken M.
  7. Micrologix 1200 Fault S:6 "21H"

    Can you post your program? That way others can view your code and perhaps spot the cause of your fault.
  8. Rotational counter help

    First, how fast are the pulses, and how long are they on and what is the scan time of your PLC? High speed pulses of short duration require special I/O modules. I suspect this is kind of slow, and normal input cards will work, but it is something to look at.
  9. peak value hold the load Amplifier

    Use a compare. IF current value > stored value THEN stored value:= current value; EndIF; In ladder use a compare and if the current value is higher, move the current value into the stored value register. You will need a "reset" to clear the stored value at the beginning of a new test.
  10. Flow Transmitter Problem

    To get a meter that will hold up in Sea Water, you are going to need an exotic alloy. Believe me I know, was in the US Navy for over 8 years. Sea water has high chloride concentrations, so Stainless last no time. You need some type of nickel alloy such as Monel ( http://en.wikipedia.org/wiki/Monel ). Naval Bronze will last a while but will get will erode over time. What is the application a sea water distillation plant?
  11. TCP/IP Connection to L35E

    WOW the The RTA unit is going into my bag of tricks, thanks Uncle Ken.
  12. How to Count Registers that <> 0 ? in PLC-5

    You could do it in ladder, with labels and jumps.
  13. How to Count Registers that <> 0 ? in PLC-5

    Will the starting and ending N registers be constant? If so, then you could use a for next loop and indirect addressing with a compare to check if each register is equal to zero or not.
  14. MINC returns zero with non-zero input?

    I can't help, but I do like the info, keep going. I 'm sorry that no one has helped you out, but maybe you can save a future soul.
