  1. Hi All: I am new to Citect and looking for a way to create 1 page that has 25 valves (genie that pops up a super genie) and some analog genie/super genies. What I want to do is create 1 page and dynamically replace everything when someone selects a different rack in the system. I have 4 systems that have the exact same equipment times 10 so I want to avoid creating 40 different pages. Can anyone help with some ideas on how I can accomplish this? Thanks M
  2. I have a FactoryTalk 8 application that exhibits some weird symptoms when I run it. I have buttons whose "visible" state and "enabled" state are based on HMI tags. The states of these buttons don't update. I have screens that fail to close when the "abort" command is issued. I have vba that connects to a tag group, which fails to retrieve the value and produces an error. Some tag values from the PLC (always direct-addressed, I think) show up correctly, even when other symptoms above are happening. These issues randomly go away sometimes after a restart and the entire application runs fine. Does anybody have a clue what could be doing this? (Using Windows 7 Professional 6.1.7601 Service Pack 1 Build 7601, SE version 8.10.00 (CPR 9 SR 7.4), Internet Explorer 11.0.9600.17633)
  3. Hi friends, The scene is like this... I have some 200 energy meters whose readings are continuously logged at 15-min intervals into a logging table. The meter does not have any other value logged. Let's consider these readings as analog tags. However these tag values are continuously increasing to ever larger numbers. Thus we have a problem for display on trends. Customer now requires that the Citect shows usage trends for any meter for a specified period of the past. That is to say, the meter that he wishes to observe is selected - along with a period typically between 2 dates (perhaps also with a sampling period) - and the trend must appear. So in other words, given a single trend object, how do you make values appear for any selected tag on this trend. Perhaps this can be overcome by some genie/super-genie mechanism. My approach to this is...For the selected meter, I use SQL to query the 15 minute logged values (also taking into account the required sampling period) taking the reading on starting date as initial. All values thereafter are subtracted -within the SQL query- and the result of this query is kept in a 2 dimensional array(x for time, Y for value) or a new database table so that the trend displays values starting with zero. This much I can do with Cicode. After this, I need a method to display the values so obtained in a trend object. Essentially this is the same as feeding a trend object with a set of X & Y values that I have in the form of an array or in a database table. I shall greatly appreciate any help to meet the above objective. Thanks for looking in. With best wishes.
  4. Reporting for Siemens PLC

    Hello, We want to do excel reports on Siemens PLC. We do not want to use historian programs. Do you know another programs?
  5. Copy HMI Tag value to parameter

    Is there any way to copy the value of an HMI tag to a parameter (FactoryTalk View ME 8). I am looking at doing something like: #100 = HMITag1 value I get #100 = HMITag1 name when I try anything meaningful. For example, if I have HMITag1 = test. I want to get #100 to equal "test", but I keep getting #100 is equal to "HMITag1". A little more background in case there is a better way of doing this. I have several components (pieces of equipment) that are the same. Each has its own program on the PLC that includes a group of tags for the component's settings. Most components use the same settings by copying tags from the controller level to the tags at the program level. A couple components need special settings. I have one HMI screen that each component will display for settings. A parameter file for each component will be used to display the settings from the proper Program. The parameter files have a tag for the program name (#100 = Program:ComponentX). On the HMI components I have {::[PLC]#100TestVar1}. This works great when #100 is a program name (the special cases). I was trying to get #100 to equal a blank so the object would access the controller level tag so any changes to the global versions would be across the board. I thought I could create an HMI string tag equal with no value to accomplish this. I just can't get #100 to equal a null string.
  6. I have been supplied with a list of tags from a vendor containing flags indicating if alarm conditions are on. These tags have the format AlarmGroup.Num.1 through AlarmGroup.Num.10 as recorded. Reading these tags as presented by making a read request to the Read Tag Service fails with general error code status 0x05, "Request path destination unknown. Probably instance number is not present.". I am using ASCII extended symbolic segments to translate the tag into a path so the instance number is not required for this approach. Upon further discussion with the vendor I found out AlarmGroup.Num.1 refers to bit 1 of the AlarmGroup.Num tag that is a DINT tag. I can successfully read the AlarmGroup.Num as a DINT but I was hoping for a more universal solution that would not require me to add solution specific parsing functionality to identify tags that refer to individual bytes from other tags and manually shift the bits as required. I am very new at this and I want to know if it is possible to address an individual bit (for reading only) from a DINT tag and how to build the path to access it. Are there other types of segments other than the ASCII extended segments required?
  7. Please Let me know How to import tags from an Excel file into my PLc programs . the tags has been generated by a guy who does the HMI wonder ware !! Pleassssseeeeeeee.
