The OPC Router Base System also contains Transfer Objects:
Constants allow enhancements to fields with constants for transferred data, for instance when the machine ID (number), the plant number and other values need to be read out.
Variables allow saving of data during transfer. Any number of internal variables with different data types can be defined and used in cross-transfer scenarios. Furthermore, several system variables allow output of current system time stamps (also as UTC).
The reading and processing of text files are possible through the file transfer object. The file is then made available as a data package. After processing, the object will move files to a separate folder so that they are marked as “processed”.
With the calculator you perform simple mathematical operations on data fields. You can define and name the number of data fields for your formula yourself. Then you define your formula, and the output data field is the result of the calculation.
For documenting the transfers you have configured, use the Note objects. These are freely placed and filled with text, which helps you or others to understand the idea behind a transfer later on.
