7.13.7.1
Activate/deactivate remote control
Remote control is a unit state and not the default one. It has to be activated, i.e. requested
by the user before the unit can be controlled remotely. Depending the settings and on the
state the unit is currently in when trying to switch to remote control, the unit can deny the
request.
How to activate or deactivate remote control of your unit via Profibus:
1.
Use the register list and find the proper command, here: Register 402 - Remote
mode.
2.
Find the slot and index values for this command in the dedicated columns, here slot
2 and index 1.
3.
From the slot configuration read the I/Q address for slot 2 to have the value for
parameter "ID", for example
a.
260 (like in the earlier Slot Configuration examples) or DW#16#104
4.
The value "Index" from the register list is submitted to the parameter INDEX like
this:
a.
Profibus: INDEX = Index = 1
b.
Profinet: INDEX = Slot number * 255 + 1 + Index = 510 + 1 + 1 = 512
5.
Use a suitable function block in your automation software, for example SFB53.
6.
Define the control value to use for this command, as described in the columns
“Data” and “Example”:
0xFF00 = Activate remote control
0x0000 = Deactivate remote control
7.
Configure the function block with ID, INDEX and control value and execute the
block. If not somehow inhibited by the unit, it should either switch to remote
control or back to manual control.
7.13.7.2
Send a set value
Any command that sets something in the unit, no matter if value or status, requires
activated remote control status. Also see “Activate/deactivate remote control“ and section
6.5.2,”Control Locations“ on page 80
.Before you send a value, you first need to select which one you want to set and you also
might need to translate it, because via Profibus/Profinet set values are transferred as
percent of the nominal values. Read sections “Format of set values and resolution“ and
“Translating set values and actual values“ for more information.
How to set the DC input/output current value:
1.
Use the register list and find the proper command, here: Register 501 - Set current
value.
2.
Find the slot and index values for this command in the dedicated columns, here slot
2 and index 24.
