The properties of a module depend on the module type. There are, however,
some properties common to all modules, which may or may not be exposed by a specific module type.
When true, the external items manager will force a full refresh initially on
start/reset when reading items. I.e. items not yet initialized in their source,
will also trigger an external item update. Default is true.
bool
150
TimeReferenceItem
An item who's value will be used as a time reference for this module
instead of the system time.
string
200
ExtItemCalculationSequence
Decides whether data validation or data transfer will be performed first
in the external item manager.
4 byte unsigned integer
300
ExtItem pass-through quality
Specifies the quality of external item values that will pass through
external item transfers. Default is 'Good and Uncertain qualities'.
Nearly all modules have some common performance properties. These properties relate to
the performance of the reading and writing of items from and to the modules.
In rare cases, a module may not have it own items.
These modules won't have any common performance properties at all. For example: the ApisLoggerBee module.
The number of item reads that were justified on this module. I.e.
the item had changed since the last time the same item was read by the same reader.
Needless
The number of item reads that were needless on this module. I.e.
the item had not changed since the last time the same item was read by the same reader.
Invalid
The number of item reads that requested items not belonging to this module.
Failed
The number of item reads in this module that failed for some reason.
The number of item writes that were justified on this module. I.e. the value
or timestamp of the item had changed since the last time the item was written.
Needless
The number of item writes that were needless on this module. I.e. the item value
or timestamp written was the same as the value or timestamp the item already had.
Invalid
The number of item writes that requested items not belonging to this module.
Failed
The number of item writes to this module that failed for some reason.
The average time in milliseconds it takes to write the specified number of items
Peak time
The maximum time in milliseconds it has taken to write the specified number of items.
Additionally, modules may have several custom performance properties listed.
To get help on these properties you must look in the help for that specific module.
