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).
NOTE:
It is possible only to force value or setpoint into other setpoint if their dimension and range are the
same (e.g. only value with dimension in hours and which is Integer 16 can be force valued 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.
7.14 Values for continuous writing from external sources
This function is especially designed for continuous writing of setpoints from external sources (e.g. via
Modbus connection).
WARNING!
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!
It is possible to use up to four different External values for continuous writing from external sources.
The values are adjusted by setpoints in Force value group. Default (also initial) value may be
adjusted, rate of change of ExtValueX (by Binary Inputs EXTVALUEX UP and EXTVALUEX DOWN) can be
adjusted as well as high and low limit of the value.
There are two way, how to adjust External values. One is using Binary Inputs mentioned above.
Second one is to write the value directly using e.g. Modbus. External values then may be converted
using PLC block convert and force into setpoint which is then continuously forced (note: NOT
WRITTEN) by the value of ExtValueX. This way internal memory is safe and no damage may occur.
External values are reverted back to their default (initial) value (given by corresponding setpoint) when
Binary Input for their reset is active (and they change to the previous value after Binary Input
deactivates). When the Binary Input is active the External value cannot be changed by Modbus writing
or by using Binary Inputs for up and down value.
NOTE:
External values are not available for external writing when any Binary Input (up, down or reset) related
to them is active.
Note also that when the controller is reset (powered down and up again), all external values are
reverted back to their default (initial) values.
