    That's exactly the thought had when first reading the post.  I don't know if historian has the capability to write to the PLC as it is generally designed to just poll for information. Noorloai, can you go back to your Wonderware tech support and see if historian has the capability to write to the PLC and perform some simple logic.  The aim would be to create an on/off hearbeat at a set interval (ie, 1 sec on and 1 sec off).  If you can achieve that then you can analyze that bit in your PLC by using timers.  If the bit from the Historian stays on past one second or off past one second then the communication is considered lost and you can act upon that however you want in the PLC.

    Unfortunately, the Historian has no way of pushing system tags value to the PLC.

    Therefore, I am looking for an alternative way to accomplish my task, like using FT SE VBA to communicate with SQL server to pull historian system tag? this is just a thought but not sure if it's possible. I have limited experience with VBA and SQL.  Wondering if someone can help with that? Thought?

    Currently, the WW Historian can read the tags from the PLC (Compact logic) using RSLinx over Ethernet DAServer Manage (DASABCIP). But I am facing an issue in finding a way to read Historian system tags in PLC. Is there any solution for that? I would like to monitor the Historian communication Status in PLC

     

    Note: HMI is FactoryTalk SE Ver 9.0

    Appreciate your response in advance.

    Hello,

    I want to monitor Wonderware historian communication status inside CompactLogic PLC and trigger a fault in PLC if communication is lost and capture this in FactoryTalk HMI SE.

    I have talked to Wonderware historian technical support and they said there is no way to do that as the Wonderware  Historian Server is a Suitelink Protocol server, so only a Suitelink Client would be able directly to access the system item from the Historian Server.

    has anyone tried to achieve this task before? is there any alternative way? and if so, can you guide me through the steps?

    Thank you and appreciate your support in advance.

    Hello,


    We have a customer who wants to connect the HMI PC of FT SE to their domain and to use their own authentication. After investigating the application, it seems our application uses a windows-linked user group and VBA script for login and security permission. For some reason, it’s not using FT SE built-in login feature.

    We have mapped the HMI PC to the domain and generated new users in the domain and tried to run the application and login with the new users, we got fail with a Permission Denied exception

    We trace VBA code and found the root cause of the issue is that the VBA script is looking at which groups the login user is a part of does not have permission to look at domain users. This is because the VBA script is running under the local HMIUser account, which does not have any visibility on whichever domain the PC is joined to.

      see below

     

    Function getCurrentUsersGroup(Optional username As String) As String

            Dim strUserName As String
            Dim Domain As String
            Dim i As Integer
            Dim userLevel As Integer
            userLevel = 0
            i = 0
                    
            Dim objGroup    As Object
            Dim objUser     As Object
            Dim objNetwork  As Object
            
            If username = "" Then
                Set objNetwork = CreateObject("WScript.Network")
                strUserName = objNetwork.UserDomain & "/" & objNetwork.username
            Else
                strUserName = username
            End If
            
            strUserName = Replace(strUserName, "\", "/")
            If InStr(strUserName, "/") Then
                ' No action: Domain has already been supplied in the user name
            Else
                    Set objNetwork = CreateObject("WScript.Network")
                    Domain = objNetwork.UserDomain
                    strUserName = Domain & "/" & strUserName
            End If
            
            Set objUser = GetObject("WinNT://" & strUserName & ",user")
            If objUser Is Nothing Then
                ' Error handling
            Else
                For Each objGroup In objUser.Groups
                    i = getAuthLevel(objGroup.name)
                    If userLevel < i Then
                        userLevel = i
                    End If
                Next objGroup
            End If
            

    GetObject looks for user object... if that user is on a domain (eg. TESTDOMAIN\domeng )

    then it will fail with a Permission Denied exception

    I am wondering if there is a function/method that we can use to solve this issue?

    I am not very fluent in VBA but I think I could stumble through it if given an idea of how to tackle this.

    Thank you and appreciate your response in advance

    Hi there,

    I am using compact logix controller 1769-L36ERM with Factorytalk view SE running on BlueLine PC communicating through Ethernet/IP. I would like to perform a performance test to check how long it takes for a command to transfer from HMI to PLC and vice versa.

    I tried to create a logic that set a tag in Plc and HMI reset that tag and monitor this tag in Studio5000 trend, however, this task doesn't give me what I am looking for.

    Can someone help on this?

    Thank you and appreciate your response in advance.

    Thanks pcmccartney1 for your response.

    My other question Can I Send  /Receives  UDT tags between those two controllers (Rockwell and Siemens)

    like Produce /Consumes tags between two Rockwell controllers? 

     if so, how ?  does this gateway enable my controllers to exchange UDT as well?

    Thanks,

    Hi there,

    Recently we have a client who has code written in studio5000 using 1769-L30ER PLC. Most the codes written using AOI. Some of these AOI used to configure hardware of third party like reading/writing Beckhoff Ethernet IO Chassis.  Client requires to move the AOI to Open Controller CPU 1515SP PC2 Using TIA PORTAL.

     

    My question, how can we establish communication between those controllers? How can data exchange between those controllers?

    By moving AOI to diffrent platform, how can studio5000 points to those AOI in TIA PORTAL? Is there any suggestion on how tags/ parameters transfer in this case?

    Is there anyone who have achieved something like this can help?

    Thanks, and appreciate your response in advance.

    Hi, 

    Well , I still have the old HMI with crimson 2 and it works totally fine. however for some reason same program in crimsion 3.1 with Cr300010 not working as expected.

    CR300010 only support crimson 3.1 software. So i didn't test 3.0 version on machine.

    how can I use that "Have you been able to verify the connection is operational using a modbus emulator? " Iam not sure how to use that can you advice me? 

    The issue that I am facing is writing to pc over Raw TCP/IP protocol. Redlion CR300010 can receive data from pc however can not send data back. 

    I have debugged my code using web server and Windows online tools and found my code is executing, however i couldn't see what i am sending to pc.

    i couldn't find a way to monitor the string data type that i am send.

     

    what could be the issue? its same code exactly in crimson 2.0. same Ip address and subnet mask. is there any suggestion that i should do to help me discover the root cause of this issue ?? 

     

    thanks

    Hi All,

    Recently, we have upgraded G3 RedLion HMI to CR300010 and migrated the G3 database crimson 2.0 to Crimson 3.1

    Currently I am testing CR300010 and I am facing an issue with communicating CR300010 with the third party through RAW TCP/IP 

    I have two ports one set as Raw TCP/IP Active and the second one set to RAW TCP/IP Passive please see the attachment

    Currently, the HMI Received data fine from the third-part ( server Pc) however, when trying to send message to the third party, the third-party doesn't seem it receive anything.

    The same program works fine with G3 HMI. 

    Are there any differences between portprint() command in crimson 2.0 and crimson 3.1?

    Can someone guide me through how can I confirm that both systems are communicating? how can I investigate this issue further?.

    I could ping the IP address for both systems from my pc which is connecting to the same network switch. 

    Appreciate your support in advance

    I would rather know why you want to write to an individual element in a SINT array.

    Seems to me that you would be better served in using the built in capabilities of both the PLC and the HMI.

    Could you explain what you are using the SINT array for and or trying to accomplish?

    I have the following:

    Array of SINT[24] call it Sorted[24] has a sorted vehicles based on its position

    If there is less than 24 vehicles on track, I need operator to insert gaps which will shift the first Array elements based on the location that operator select

    I want operator to select from HMI whether this location is full or empty which write to another Array of SINT[24] call it Gap[24], 0 means full, 99 mean empty  

    Example:

    Sorted[21]= [6,7,8,9,…..,10]

    Operator can add up to 3 gaps, Based on operation selection Gap[24]= [0,99,99,99,0….0]

    Output Array = [6,99,99,99,7,8,9,…..10]

    So what I am thinking is to map 24 buttons on HMI to Bool[32] on PLC only 24 used,

    Then if operator select that bit it will write 99 to Array SINT[24] Else it will write 0

    Then I can compare my sorted array with my gap array and find the output array.

    If you have a better solution/idea would be appreciated.

    Do the array elements match up? In other words, will pressing BOOL[7] write 99 to SINT[7]?

    Why 48 rungs with only 32 buttons? Do you have an example of what you've done so far that does what you want for one button?

    “Do the array elements match up? In other words, will pressing BOOL[7] write 99 to SINT[7]?"

    ·         Yes It does match

    Why 48 rungs with only 32 buttons? Do you have an example of what you've done so far that does what you want for one button?”

    ·         As I have two condition 0 and 99 , and I have 24 elements

    Hi All,

     

    I have a question on if its possible to do indirect addressing of individual bits of a tag of datatype dint in studio5000 ladder logic?

    I am writing a routine that should  loop through the individual bits of the tag of data type dint and do processing .

    Like instead of using OTE instruction ConfirmRequest[rvIndexSafety]

    where confirm Request is BOOL[32] elements 

    if condition true and rvIndexSafety =1 => it will set confirmRequest[1] 

    I need to use DINT and set DINTDataType.1 

    How can i approach this?

     

    Thanks,

    Hi All,

    I have an issue and hoping you can help me with the solution.  I am not sure how can I use TON within loop in ladder logic?

    I have made a loop using JSR and LBL to execute Sub, in this subroutine I need to use timer or delay before turning the output on, as I am facing an ON/Off condition which turn the output on.

    Is there any suggestion ?

    Appreciate your response in advance.

    Thanks,

    well, the value in array 1 changes dynamically, but in array 2 is not. and its ascending order.

    I want to check the array 1 element value with array 2 values and get the closest bigger  number in array 2 so I can update my target to the closest number  and repeat that for each element in array 1

    example:

    target position =0 

    current array[1] = 20000,

    compare with the constant array 2 , which is between 18000 and 25000 values

    then take the closest bigger number and move it to the target position

    Hi All,

    I have two DINT array for example array1 [200] = [ 0, 1.........199], array2[100] = [ 20,40,60 ...180]

     array1[30] = 30 need to compare it with array2[100]  and find the closest range.

    in my example array1[30] is between array2[0] and array2[1] how can I do that in studio5000?

    I haven't worked with array before and therefore your support is appreciated 

    Thanks
