Reading (and writing) group address values in an existing installation can be done either via Group Monitoring or directly in the List View. To do so, just select a group address assigned to the group object and open the context menu.
Read Values/ Write Values
•Values can be read/ write either via the context menu or the group monitor. If on performing of function the monitor is not (yet) open, it will be opened in a new separate tab.
•If the corresponding DPT is know at the GA in the List View (over the GA directly/ linked GO), over an additional fly out at the context menu the concrete to be written value can be chosen directly.
1.Read a GA in the List View with/ without DPT performs a "read" command, without insert the - to be read - GA in the group monitor.
2.Write a GA in the List View with DPT performs a "write" command, without insert the - to be read - GA in the group monitor.
3.Write a GA in the List View without DPT requires a manually performed "write" command in the group monitor, for this the to be written - GA is inserted in the group monitor.
In all three cases the corresponding read/ write command is visible in the group monitor. Not inserting the GA in case 1/2 in the group monitor prevents the unintended change of previously explicitly chosen GA in the group monitor.
For GAs, ETS offers the option of analyzing the current value of this group address not only using the monitor, but also directly at the GA in the GA structure itself. To do so, just display the Last Value column in the window with the visible GAs; the value of the GA received from the bus will then be displayed here.
•The GA monitor must be running.
•The field Last Value is blank as long as no value for this GA has been received.
•The current value will only be overwritten by a new value (no value timeout after time X).
•The values are deleted and are not saved when
othe GA monitor or ETS is closed
•Bear in mind that any value written will have the same effect as if the value were sent by a device (e.g. sensor) in the installation. Sending unexpected values or values to not yet configured devices may possibly result in unforeseeable situations.
