Setpoints must not be written
continuously
(e.g. via Modbus connection)! If continuous change of setpoints
is required, combination of External values and Force value function needs to be used. The memory that
holds setpoints is designed for up to 10
5
writings. Than memory may be damaged!
Setpoints that are available for forcing may be identified by Force value button on the right side in GenConfig
(see the figure below).
When the button is clicked, Force value dialog appears.
Add or remove Force value
Change position of Force value functions (priority)
Change the name of the source setpoint
(available only for Force value 1-16 setpoints)
Select the value that should be forced (i.e.
the value of the particular setpoint)
Rename binary input that
triggers the forcing
ID of binary input
(1 for ForceValueIn 1 etc.)
Select source setpoint or value
For example if we add
Force value:Force value 1
to be forced to
ProcessControl:Export limit
as value 0
(DISABLED) by Binary Input F
ORCE
V
ALUE
I
N
1 we can change the function of Export limit from ENABLED to
DISABLED by activation of F
ORCE
V
ALUE
I
N
1. It is possible to rename the setpoint to e.g.
Force value:ExportDisabled
and Binary Input as well to e.g. D
ISABLE
E
XP
L
IM
. The function will not change
(only the corresponding names).
It is possible to use several force value functions for one setpoint. If more than one forcing Binary Input is
active, the one with the highest position (lowest number in the Force value dialog) is used.
It is possible as well to use one Binary Input to force multiple setpoints (e.g. in case of complex function
change).
N
OTE
:
It is possible only to force value or setpoint in other setpoint if their dimension and range are the same (e.g.
only value with dimension in hours and which is Integer 16 to a setpoint with dimension hours and which is
as well Integer 16). You may use PLC block Convert to change the dimension and range if needed.
