I/O tag address. Address type depends on the communication protocol of the station, that is the parent of particular I/O tag. Address is stored in the configuration database in text form. Particular communication protocol converts this address into a binary form. For internal communication protocols of D2000 system, a protocol-dependent dialog box with the validity check of given address is used during I/O tag address configuration. For external communication protocols (OEM _Protocol1 Protocol 1 up to OEM _Protocol16Protocol 16) of the D2000 system, address is entered directly in text form.
During saving of the I/O tag configuration, the uniqueness of its address is tested. If the address of I/O tag is not unique (within a parent station), the system will inform about error.
By choosing the option Yes, a new CNF dialog window opens. Only I/O tags with conflicting address sharing a common parent are displayed in this window. The user can (but does not have to) change the address of these I/O tags.
