  1. Hi guys,

    So I was wondering if there is a module that will measure the Hz of a 3 phase supply? I need to be able to measure the Hz of the supply and to be able to record at 50 ms . 

    I was hoping that there might be a card that would do this on the Micro 800 series. I know I am probably asking a lot here, and that maybe this kind of card would be on some of the more expensive series

    I have read up a bit more and have some questions.

    Can you set up  a 1756-EN2T as an OPC Client? Could this be an option.

    Or would there be a Red Lion product to achieve this? 

    Or would the Prosoft EtherNet/IP to Modbus TCP/IP to OPC UA Server Gateway PLX32-EIP-MBTCP-UA be used either? 

     

     


  3. Hi,

    I have an Array of 120 DINT's, 120 positions. Each Index of a Dial equates to One DINT (position), and if a bad part is detected then a "1" is put into this DINT, good part is "0". The DINTs are cleared after each full revolution of the Dial.

     What that I am trying to check to see if a "1" is put into any of these, i.e. a bad part. I was trying to use a FSC Instruction, but I haven't used before, and would be grateful of some help with this.

    Thanks Conor


  4. Hi guys, I have a PLC that can be slow when doing online edits. There is an STI called but all of the code in this routine is obsolete. How do I make sure that this routine is not called? I see that there is an Enable bit S:2/1, and this is set to 1. If I set this to Zero will this stop the routine from being called? Thanks Conor

  5. Hi, Another great way to check your system is by using a current loop calibrator, something like the Fluke 773 Milliamp Process Clamp Meter, though you can get other cheaper ones as well. This way you can "inject" a 4 - 20 mA signal into your system, and you will then be able to see the full range of your AI. It is probably one of the first checks that I would do when we are troubleshooting problem with Instruments as well. Conor

  6. Site looks very good. i like the forum it that you have added as well. I just clicked on a couple of links and had to use the back button to get back there first. When I looked a little harder I found that I could get back via the Supprt link above. So I think that if you had larger tabs across the top to navigate back to support home. I have done a few web pages for work (internel) and I have fond that when I made the tabs larger that the end user didn't have as many questions when the pages went live. Conor

  7. Hi Mickey, I am not sure if I am allowed post directly to the forum because of IP. It is a program from a vendor that we don't have any contact with now. I checked this morning and have attached another screendump from code. Output is now set? Conorslc_pid_1.bmp

  8. Hi, Normally if you are upgrading from 9.x to 10.x, Wonderware should be able to assist you with the migration. There are various tech notes on configuring Wonderware that are freely available out there. The SMC settings should come across, but if you still have the old XP PC running you should be able to set-up the new PC the same. I thikk that there is migration manual on the installation DVD that comes with a new install of Wonderware as well. This should assist you as well. Conor

  9. Hi guys, Just checked the manual again. M8000 is Always ON PLC Run M8001 is Always Off PLC Stop M8002 is Initial Pulse (NO) M8003 is Initial Pulse (NC) Of course I was looking for first scan, and they call is Initial Pulse At ;east with your help I was able to find the special bits M8000 etc Thanks again

  10. Hi guys, I dont normally post on the Mitsubishi forum, but I have a question for you guys. In AB there is normally a first scan bit I am working with a Mitsubishi FX-1S, and cant find the First Scan bit instruction. Basically I would like to make sure that if my machine is powered down mid cycle that when it is powered back on that it completes a purge sequence. I would normally use a first scan bit. Any help on this would be great Thanks, Conor

  11. Sorry I worded that wrong. I set up a watchdog timer in a remote PLC that triggers site alarms. I am looking at a bit coming on and off in each of the PLC's and triggering a "Watchdog" alarm on a PanelView that displays the site alarms. Basically I have nothing special in the PLC that faulted Sorry for the confusion Conor

  12. For some idea's that may have caused it. I have 9 of these machines, all with the same program in them. The only time before that I saw one of the PLC's faulting was when an Analogue Input card had gone faulty. So after that I put in watchdog code to monitor each of the PLC's.

  13. Hi guys, I just had a SLC go into fault. When I went online the error was as follows: "The user watchdog scan time has been exceeded!" I cleared the fault and the PLC came back fine. Can anyone throw any light on this? See attached screendump Thanks, Conor blower_g_error_5_11_13.doc

  14. Hi guys, I have a pump set that I have just installed three new Powerflex 40 Drives. I have set-up the drives and they are unning fine. I have a PID set-up and this will control ok too. Everything alright so far. Now I need to maintain a pressure of 7.5 bar with these pumps. One pump will not reach 7.5 on its own. I am not sure of which is the best way of running these pumps. Currently I have the Duty pump running flat out at 50 Hz. I am then using the PID to vary the speed of the Assist pump. Is this the normal way that this would be done? Or would I be better to run the two pumps from the PID and vary both? Any help would be great, Conor

  15. Hi Ken, Without physically pullig out the processor, is there a way of checking to see if there is an EEPROM? I looked up the SLC manual and from there I was able to check system bit S:66 (Flash EEPROM size). This has a size of 512 in it. I also checked the N9 integers and they had the strange values in them again. I checked on my Scada and couldn't find anything that would be writing to this Integer either. Conor

  16. Hi Gromit, I just searched for this on the tech support website and it says that Last Scan S:8 and Max Scan S:9 can be reset by putting a zero into these bits via RSLogix5 software. The article number on tech support is 61150. I had checked the Enhanced user manual, 1785-UM012D-EN-P, but couldn't find anything in that about resetting. Conor
