I I I I I LINKGPAR
With LINKGPAR it is possible to link a pre-defined
global parameter or a free internal user parameter
with the LCP display. Subsequently it is possible to
change this parameter via the LCP or read out the
set value.
When a linked parameter is changed with a SET
command, the new value is also automatically
transferred to the LCP , but is not changed in the
factory settings since the SET command only has a
temporary effect.
If the user changes a linked parameter on the LCP ,
the new value is executed. Only after the user has
confirmed this value with OK is the new value
saved permanently as a user parameter in the
EEPROM.
NEW: The command LINKGPAR tests whether the
value of the user parameter is within the specified
range. If not, the corresponding limit is used and
this value saved. This ensures that a display
appears.
Summary
links global parameter with LCP display
Syntax
LINKGPAR param optpar "text" min max typ
Parameter
param = global parameter name or user parame-
ter number (130–229)
optpar = LCP parameter number (710–779 and
795–799)
text = descriptive text for display
min = minimum value for this parameter
max = maximum value for this parameter
typ = type of parameter
0 = offline, i.e. changes are only active
after they have been confirmed with OK.
1 = online, that means changes via the
LCP display are active at once

I I I I I LINKSYSVAR
The command LINKSYSVAR links the system
variable SYSVAR[indx] with the VLT Parameter vltno
(795-799) and the display text text. This means that
you can link internal values on the display without
using LINKGPAR.
If, for example, you are compiling with #DEBUG
NOSTOP, link the internal line number with the VLT
parameter 795. Then you can selectively observe
the program execution.
Summary
Link system variable with LCP display
Syntax
LINKSYSVAR indx vltno "text"
Parameter
indx = Index of the system variable SYSVAR
vltno = LCP-Parameter number (795...799)
text = descriptive text for display
NB!
The parameter vltnr is updated every 40 ms.
Therefore, if five parameters are linked in
this way, it takes at least 200 ms until the same
parameter is updated.
