  1. Good morning all! I'm just getting into this world of controls and automation and need a way to simplify my life when it comes to discrete alarms. I do not care to separate them by tag so long as I can create a personalized for each bit/alarm triggered. What is the best way to list hundreds of alarms in a single tag? Can we make use of a struct data type? If so, what would this look like? I understand I can use something like a tag of data type word, such as "Faults" MW100 and then reference M101.0, M101.1... M100.0, M100.1 (notice the order), but this only allows me 16 total discretes per tag.  Sometimes I'll have more alarms than 16 and sometimes way less. I'd rather not seperate them in this manner if I can avoid it. Your assistance is much appreciated!   [edit] Siemens TIA and WinCC v15
  2. Factory talk view

    Hi all, 1. I'm working on alarms in FT view ME with rslogix 500. I have seen all the alarms in my plc program are kept in the N7:1 and N7:3 out of which all bits for N7:1 is used and 9 bits for N7:3 is used. So right now I'm creating the alarms messages for N7:1 I went and created tag with name ALARM1 digital bit and used the device address as ::[shortcut]N7:1/1 and then used the same alarm tag while creating alarms and kept trigger value as 1. But while reading some post, few of them has mentioned to use L16 L32 in address bit ::[shortcut]N7:1(L16) Can't I use this ::[shortcut]N7:1/1 ? 2. Basically I'm converting pv550 to pv700. So I went and check alarms in pv550 in panelview 32 and I have seen there we have use "ack tag" as N7:2. because in plc program it was mentioned in description of N7:2 as ALARM RESET ADDRESS ARRAY. DO I have to use this N7:2 in acknowledging the alarms. Please some one help me
  3. Hi All, I have a requirement from a customer to acknowledge alarms from either of two  NS15 HMI's in the system. Can anyone provide info on how I may be able to acknowledge or delete alarms on one HMI which would also acknowledge or delete said alarm(s) on the second panel?  Both of the HMI's are polling one controller for alarm status so I assume that each time an alarm is acknowledged or deleted it would have to alert the controller which would then send something to the second HMI to clear the alarms? Any help is appreciated.
  4. iFix alarms all at once

    Just after midnight last night a site received EVERY alarm on the HMI but nothing had shutdown.  Has anyone ever seen this?  Does anyone know why this happened or how to prevent this from happening again?  The site is not manned around the clock and the operator received a call out that the whole plant went down.  Thanks!
  5. Monitor alarm block

    Hi all, I would like to monitor the status of my alarm word (MW100) and if any bit turns from 0 to 1 then an alarm signal should be generated, am new to siemens plc and am having a tough time accomplishing this easily. In omrom CX programmer its quite easy to do. Could anyone help me on this using ladder logic, all help will be deeply appreciated.  Regards, Ablex  PS: I'm using Step 7 V5.5
  6. RXDU issues

    I have a data logging process on a CJ1M CPU13 via RXDU command on port 2 of SCU41-V1 It has been working, but has stopped.  There are 2 identical machines.  Both Honeywell bar code readers work on 1 machine, while the "RD2" led stays lit on one machine, and wont complete the RXDU command.  On the working machine, it simply flashes quickly during data receive.  I have compared the program in both, and it is identical. Cabling from both machines have been tested - works on one, not on the other.  Even swapped out SCU41-V1 with same results, so I am pretty certain it is a setting in the main processor of the non-working unit.  I did a compare of SCU settings and they are identical. #0 is moved into C  #2213 is moved into C +1 on first cycle.  Unit number is 3 1594.06 never seems to complete, which is an open contact in series with A202.02 (N.O.) to trigger RXDU (255) A202.02 is value 1 1594.06 stays at 0 when I trigger 1594.06 via laptop, it sends garbage data once.     Any ideas?

  11. Factory Talk SE CAB file missing

    Hi guys, I recently was asked to configure a computer to host an Factory Talk SE Client application. I was able to get everything working except the trends and the Alarm window, all I have is the cross hatch screen. at the bottom of the screen it is saying cause: Trend: CAB file missing on the server: http://hmi1/RsviewActiveXControlSetup/RSTXView2ocx.CAB. I have worked on this for a while and am stumped. All the other computers on the same domain network are working fine, so it leads me to believe my problem is with my installation on the new computer. Any suggestions or if you need more input please let me know. Thanks
  12. Hi, to all. I have a question concerning the current alarms of CX-Supervisor, I'm using the version 3.22. I want to do a custom alarm view where the alarm messages have a different colors depending on the priority (ex. red for high priority, yellow for medium priority, etc...). I want also that the alarms are ordered by date & time, first the latest. The alarm object is not good because doesn’t allow to order by date & time and you can decide only one colour for all the alarms.The current alarm dialog box allows to order the alarms but non to customize the colors. I did some test and I've seen that I can fill a list with different line colors by using the ActiveX object Microsoft ListView Control 6.0, but I need the current alarm list to do it. I don't know where to get this list. The alarms history is stored in the .UAL and .UAB files but I didn't find any file with the current alarms. Does anyone know how to get the current alarms list? Does anyone know another way to have the same effect? Thanks in advance
  13. Move Function Not Working

    I am very new to PLC's, I work in a power plant and we have an ABB DCS. We have some vendors that use PLC's and they try to make them work with our system. Currently I am working on a project were I am trying to add 8 analog outputs to the PLC. I am working with two 1756-L71 controllers (redundant) and the rev for the program that was written 20.01. Basically I have 8 analog inputs that I want to bring to the spare analog outputs that I have. I want to see these inputs in our DCS. I wrote simple logic that at the end of the rung has a move block moving the source which is the input and taking it to the destination which I made an alias tag for the output channel that would correspond. Problem is I can see the source number moving, but the destination number stays at 0. I can type a number into the destination and it will work. I can see my 4-20 signal I am sending out in the DCS. Everything before the move function is true, I have and open contact, and a closed contact and they both are green. This is happening on all eight of my outputs that I am working on. Please help I have learned a lot from this experience but I cannot figure out what has me stuck this time.
