Check that you have specified the correct field name and database name.Īn operation has been attempted on a file or device that is of the wrong mode, for example, you tried to perform a seek on a printer device. A function that is trying to access an individual field in a database cannot find that field. The specified field does not exist in the device or database.

There could be a disk full error, or a disconnection from of the file server may have occurred, or the operating system is out of resources.Īn attempt was made to open a file of the wrong type, for example, you tried to open an ASCII file as a dBASE file. During a function call (that tried to write to a file), a write error has been detected.

Either an error has been detected during a read operation, or the end of file was unexpectedly found, or a disconnection from of the file server occurred, or the operating system is out of resources. (Check with your network supervisor that you have correct rights to open the file). There may be a mode error (for example, from trying to open a read-only file in write mode), or the file may be open by others, or the operating system resources may be too low to open the file.Ĭheck that the file does exist (use File Manager), and that you have the correct rights to open it. During a function call (that tried to open a file), the file could not be opened.

This error will also be detected if you try to call TrnDelHistory() on a file that has not been added using TrnAddHistory(). Call the function again with the correct file name. During a function call (that tried to open a file), the file could not be found. The specified file or device does not exist. Call the function again with the correct path. During a function call (that tried to open a file), a non-existent path was specified. The specified path to a device or file does not exist. Define a larger array or reduce the maximum data size requested. Try again by calling the function twice, with half the data in each call.Īn array passed to a function is too small for the data requested. More data has been passed to a function than it can write to its temporary buffers. You can disable range checking on PLC variables with the CodeSetMode() function.Ī buffer has been overrun. An out-of-range value has been passed to a function, or an array index is off the end of an array, or a value that is outside of the specified engineering scale has been assigned to a I/O Device variable. Contact Technical Support for this product and provide details on what causes the error.Ī numeric value is out of range.

However, more often that not, it is because it does not exist.Īn internal Citect SCADA software error is detected. The reason for a tag being unknown by the I/O or alarm system may not be that it does not exist, just that the server it is on is yet to come up and tell us about it.

The tag is not known by the server being talked to at this time This occurs for scheduled or Dial-up devices. When the error for a tag has specific values the tag test can show "#WAIT" for this error. The unit the tag is on has not been connected to yet The table below describes the general errors in Cicode.
