  1. GE Historian5.5 spikes?

    Good morning ladies and gents, I was wondering if any of yu have experienced issues with GE Historian 5.5, namely failing to scale a data point to ENG units and saving the raw value. thanks in advance
  2. S7-1500 FW v 2 / Profinet issues non-Siemens devices

    Hello: Has any body encountered Profinet IO cyclic communication establishment problems between the latest S7-1500 PLC with firmware 2.0 or later and non-Siemens Profinet devices which had previously passed conformance testing campaigns? Thanks for your comments.    
  3. How to Scale a analog value?

    hello guys....How are you all? im new to siemens plc, so i dont know how to scale analog value in STEP7 plc's? and also i dont know how to use AI,AO,DI,DO? how to address them? can anyone help me? 
  4. I have a problem trying to scale a floating number coming from an HMI to a value to use on PID instructions.My problem is on the scaling instruction.Whenever i try to run on cx simulator it gives me an error My setup of the scale parameters are (using SCL3(487)) D616 #0000 D617 &350 D618 #FFFF D619 #FFFF D620 #0000 My ladder to use the float number is: *F(456) Value +10,0 D2120 FIX(450) D2120 D2062 SCL3(487) D2062 D616 D2072 The error that throws is 0x80F0 Thanks in advance for any help PS Also tried all Scaling instructions.I think my problem is the setup of parameters for scaling instructions  
  5. I'm having Allen Bradley PLC communication issue to a shared remote Rack. The Remote rack en2t card seems to reset. The Network path to it PLC to EN2t to N-tron switch to (Dell Managed Switch) to fiber converter to fiber to fiber converter to n-tron to remote en2t card I've found that when I replace the Dell Managed switch with a generic link sys switch. My I/0 OK Status light on the PLC will only blink 2 times a day compared to the Dell N3048 switch which will cause the status light to blink >500 times a day. I have fault code that runs in the PLC to determine what's causing the I/O fault and it Always points to the same remote rack. I've swapped fiber converters patch cables n trons en2t cards nothing effect it except the managed switch replacement...I haven't replaced the physical remote rack yet, cause I'm having trouble justifying it, since I get such a dramatic change when swapping the switch.     Anybody have any thought or ideas please provide...

  8. Setting up 1794-IF8IH card

    Good Afternoon, This is the first time I have used a 1794-IF8IH and was after some help with setting up the analogue scaling. Normally in logix5000 on analogue cards you can select the desired scaling for each channel of the card under the configuration tab by selecting 0-20mA or 0-10V etc in the drop down boxes. According to page 16 of the manual http://literature.rockwellautomation.com/idc/groups/literature/documents/in/1794-in115_-en-p.pdf it appears as if this has to be setup in the PLC tags. Is anyone able to give an example of the PLC tag address where I would place a value which represents the scaling that I was hoping to use ie: DropNumber:5:C:Ch0DataFormat_0   Cheers,   Robbo    
  9. Data Historian Speed

    I was just curious on which type of data historians are considered fast at retrieving historical data.  For example, if I wanted to trend a tag at a one second interval to review an event that took place a year ago and compare that to the same tag in real-time, what historian does this the fastest?
  10. Hi everyone, I'm about to use the wonderware historian redundancy feature and I would like to have some opinion about it. - Someone has already use it ? - Any major bug/adivse ? - Would you recommend it ? An other word any comment would be appricated !!! Thanks
  11. ROC800 SCALING ISSUE

    Hi. So, technically the ROC is a flow computer but hopefully I can find some help. We are using the DS800 in the Roc. I have pressure transmitters in the field. They are ranged 0-2000 PSIG. Im using the ROC as the master and Freewave radios as slaves. They are transmitting the transmitters signal wireless and it comes in MODBUS. When I perform a loop check, the URV comes into the ROC at 1984 PSIG on all my transmitters. I have checked the float scales and they are correct. They are using an integer scale and I am not familiar enough with it in order to mess with it. I am currently doing some research on the subject. I was hoping someone could help shine some light on this and help me see it differently. FYI, I have already contacted supportnet at Emerson and the keep insisting that the transmitters aren't calibrated correctly. I have already confirmed that they are calibrated correctly and they are all brand new. They are ranged correctly as well. I can provide and roclink files if that would help. Thanks!!
  12. 1738-EP24DC

    I have an EP24DC module that will not supply power to the bus. Swapped the module out and still have the same issue. Any Idea's !
  13. Hello all, first post here, and thanks in advance for the help. I'm a fairly green SCADA and controls designer and although I worked fairly extensively with these systems in the past, I followed a sightly different career path for the last several years and haven't had my hands on a PLC that whole time. Started a new job and am rebuilding my knowledge with it. Fortunately my company afforded me a PLC to take home and mess around with for this purpose. I feel pretty dumb as I am struggling to even connect with it, haha. Here are the stats: Backplane: TSXRKY4EX (end caps are securely in place) Power supply: TSX PSY2600 Processor: TSX P57 6634 First I attempted to connect via ethernet, using the IP address sticky-noted to the front of the processor: 10.1.1.80. No luck, "PLC address is incorrect, or PLC is busy, yadda yadda". As I understand, the default IP address can be converted from the MAC address. The last two MAC address numbers were: CF.87, which gave me the address 85.16.207.135. Same result with this. I tried pinging both address from the command console and had no luck there either. I happened to have a USB to unitelway adapter (Telemecanique brand) and attempted using that as well, Address:SYS.. Media:Unitelway. No luck, same answer. After a lot of frustration and hours spent scouring the internet for answers, I took the nuclear option and pulled the battery (while unplugged) and replaced after 30 or so seconds. I was assuming this would clear the memory and reset the IP to default (85.16.207.135), afterwhich I could reconfigure and start fresh. Unity still can't connect nor can I ping it. It should be noted that I am using Unity Pro XL Version 8.0, on a VMware image. I did attempt pinging from both the VM and the host machine, both can ping other known devices so connection by the VM through the host shouldn't be the problem. Neither the VM or the host recieved a ping reply from the PLC. Any help would be GREATLY appreciated. I feel I have exhausted all options and I hope I didn't shoot myself in the foot by pulling the battery. As far as whatever program was on it before is irrelevant, the PLC was given to me to do with whatever I wish, so memory loss wasn't a danger. I just need to connect to it. Thanks!!
  14. Scaling in FX 3GE PLC

    Can anybody please help me? I have FX 3GE plc and reading (4-20) mA signal using built in analog input as 0 to 3200 counts. I want to display this counts as (0-1500) RPM. I searched the manuals, SCL and SCL2 instruction will work only in FX 3U PLC not in FX 3GE plc. Please help me to scale the values. Thanks in advance With Regards Joshua jo2ham@yahoo.co.in
  15. Trying to add points to a QLC link from WDPF to SLC5/04, incorporating a 1770-KF2 DH+ interface module. This link has been in place for years, incorporating only DCS reads (both digital and analog). We recently added several more DCS reads successfully, but cannot seem to get digital or analog DCS writes to be seen by the registers in the SLC5/04 data table. Could this be a limitation by the 1770-KF2 module, or is there a more probable reason? SLC5/04 DH+---------1770-KF2---------QLC Could Duplex settings on the 1770-KF2 module have a bearing on this dysfunction? Successful DCS analog reads PT101, N9:2, A0000 PT102, N9:3, A0002 DP103, N9:4, A0004 Unsuccessful DCS analog writes PV101, N9:18, A0500 PV102, N9:19, A0502 PV103, N9:20, A0504 Any insight would be greatly appreciated. Thanks.
