To activate the transparent gateway, start GateWay Client with one or more /ROV parameters (Read Object Values).
Syntax: /ROVobj_mask1[+][,][obj_mask2][+][,]......
...
/ROVSELF.KOM+ | Ensures the value transfer of the SELF.KOM process together with its children (lines, stations, I/O tags). |
/ROVM.* | It is used for value transfer of the I/O tag which name starts according to the ordinary naming 'M.'. |
/ROVM.OBJ1,M.OBJ2 | Value transfer of objects M.OBJ1 and M.OBJ2. |
Object exclusion
If it is required not to transfer the values of specific objects, it is possible to start the GateWay Client process with one or more parameters /XOV (eXclude Object Values).
Syntax: /XOVobj_mask
Objects whose names match the specified mask will not be transferred (not even their descendants). The /XOV parameter has a higher priority than the /ROV parameter.
Example: The transfer of all structured variables except system structures can be achieved by specifying /ROVSV.* /XOVSV._System*
Pairing objects by UID
Transparent gateway supports pairing not only by object names but also by UID objects. This feature is enabled by the start parameter /UID, which must be used when starting both the GateWay Client and GateWay Server processes.
This feature can be used to implement the functionality of a transparent gateway regardless of changes in the names of the objects (provided that they have the same UID), i.e. objects can be renamed.
...
/E+DBG.GTW_TR | Enables listing of the debug information about the objects when executing for operations of the transparent gateway. |
/E+DBG.GTW_TR.VAL | Enables listing of the debug information about the value transfer of selected objects to the destination system. |
