Number Effect/causes Remedy
190009 An attempt has been made to assign the tag a
value which is outside the permitted range of
values for this data type.
For example, a value of 260 was entered for a byte
tag or a value of -3 for an unsigned word tag.
Observe the range of values for the data type of the
tags.
190010 Too many values are written to the tag (for
example, in a loop triggered by a script).
Values are lost because only up to 100 actions are
saved to the buffer.
The following remedies are available:
• Increase the time interval between multiple write
actions.
• Do not use an array tag longer than 6 words when
you configure an acknowledgment on the HMI
device using "Acknowledgment HMI".
190011 Possible cause 1:
The value entered could not be written to the
configured PLC tag because the high or low limit
was exceeded.
The system discards the entry and restores the
original value.
Possible cause 2:
The connection to the PLC was interrupted.
Make sure that the value entered lies within the range
of values of the control 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:
An attempt is being made to assign a value to a
counter that is outside the valid, PLC-specific value
range.
A tag of the type Integer should be assigned a
value of the type String.
Check the range of values or the data type of the tags.
190013 The user has entered a string that is longer than
the tag. The string is automatically shortened to the
permitted length.
Only enter strings that do not exceed the permitted tag
length.
