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 curent system time stamps (also as UTC).
Reading and processing text files through data transfer objects is possible. The file is compiled as data package. After processing, the object can relocate files into separate folders that are marked “processed”.
