  1. industrial surplus

    Do you have a profibus cable tester?
  2. Depends on the size of the system. How many stations, how many plc's?
  3. PLC-5 BTR setup screen for manalog input module

    You are on the right track. Way back when... there wasn't any setup screens. You read the manual, and typed in the configuration to various words of the Block Transfer. Later, Rockwell made the software nicer and added the software setup screens, and gave you the ability to add the ladder logic. So..if you have an older application that was written before the software enhancements, good chance the hardware  configuration was never setup.     I have never did one on the fly, but I think you should be able to do it. Just make sure you enter in the information exactly like it is listed in the Block Transfer.
  4. Hi sir I have jst become a member in this site n I find this site very useful as it is of my line of work. I am working on a port of entry n we have gottwald mobile habour crane which is no not working due to its failure to load the project file. All is happening is that one pop up window showing a Database synchronisation error limit exceeded message which I have no idea as to how to do anything about it.. I would appreciate a lot if u could possibly guide me through thank you sir.. My email is kishananand855@gmail.com 

  5. Controller Connectivity Problems

    Try browsing to the web page of the EN2T cards. They show a lot of information about connections and such, might give you a clue.  
  6. Is it possible to add and a configure an additional column in the Trend statistics section, I would like to show the slope of the section selected for statistics. -thanks, ken
  7. 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.
  8. Contactors in Class I Div II area

    Contactors must have hermetically sealed contacts, or be in purged enclosures.
  9. 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
  10. 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.
  11. 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.
  12. 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.
  13. 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.
  14. 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.
