6.8 Auto-ID
This function facilitates first commissioning of the devices in the plant. The node numbers
can be assigned by the superordinate control or by pressing the relevant button on the device
concerned. The functional principle is illustrated in Fig. 5: Auto-ID function.
The Node-ID 1Fh (31d) is factory-set. Now, the SIKONETZ5 master must send a write command
on parameter D2h: Auto-ID assignment with the new Node ID to be set to the bus
subscriber(s) with the current Node-ID 1Fh and wait for an SIKONETZ5 response. A write
command on devices with a node ID different from 1Fh is responded to with an error message.
"New ID" will be displayed on all devices that have the current Node-ID 1Fh. The user must
press the key on the device intended to adopt the new Node ID. Afterwards, this device
sends a SIKONETZ5 response with the parameter D2h: Auto-ID assignment. The new Node-ID is
taken over and stored in the EEPROM. The initialization phase is finally repeated so that the
new Node ID applies henceforth. All other devices do not react. Afterwards, the control unit
can execute a read command on a parameter for the node with the node ID 1Fh for instance
in order to detect any other devices with node ID 1Fh present in the bus. If so, the procedure
may be repeated until all devices have received the desired Node-ID. The Auto-ID function is
aborted in the AP10S when an illegal value was sent for the new ID. Error messages will be
returned in this case.
Use of this function is optional. The node numbers can also be set via parameterization (see
chapter 4.3: Parameterization of the position indicator).
