A-15
Number Effect/cause Remedy
190002 The tag is not updated because communication to
the PLC has been interrupted.
Switch on communication via the system function
"SetOnline".
190004 The tag is not updated because the configured
address is not available for this tag.
Check the configuration.
190005 The tag is not updated because the configured PLC
type does not exist for this tag.
Check the configuration.
190006 The tag is not updated because it is not possible to
map the PLC type in the data type for the tag.
Check the configuration.
190007 The tag values are not modified because the
connection to the PLC has been interrupted or the
tag is offline.
Switch to online mode or
!
e-establish connection to the
PLC.
190008 The threshold values configured for the tag have
been violated possibly due to:
•
an entered value
•
a system function
•
a script
Note the configured or current threshold value of the tag.
190009 An attempt has been made to assign a value to a
tag which is outside the value range permitted for
this data type.
E.g., a value of 260 entered for a byte tag or a
value of -3 for a word tag without a sign.
Note the value range for the data type of the tags.
190010 Too many values are being used to describe a tag
(i.e. in a loop triggered by a script).
Values are lost because the maximum of 100
actions have been stored in the buffer.
Increase the time interval between the multi-writing tasks.
190011 Possible cause 1:
The value entered could not be written to the
configured PLC tag because it was either above or
below the value range.
The input is rejected and the original value is reset.
Possible cause 2:
The connection to the PLC has been interrupted.
Ensure that the value entered is within the value range of
the PLC tags.
Check the connection to the PLC.
190012 It is not possible to convert a value from a source
format to a target format. For example:
A value should be assigned to a counter which is
outside the valid, PLC-dependent value range.
A tag of the type Integer should be assigned a
value of the type String.
Check the value range or the data type of the tags.
