PCo maximum tags read in Notification (tag values ---)

I'm attempting to build a notification output from PCo to MII that contains the values from 5345 tags from a single OPC UA Source System. Several of the tags are concatenated within the notifcation output.

The output sent to MII contains many tags with a Quality "None" and values of "---".

I assume this is due to a limit being hit - either a maximum number of tags or a timing problem in PCo or the OPC UA server.

Could anyone suggest specific settings to check or if there is a hard limit in PCo?

Example of the values sent (using | character as separator within the contatenation).

Good;

<st_Cell21st_Bond6 quality="Good" timeStamp="2020-07-31T10:35:06.8766069Z" type="xsd:string"><![CDATA[2|7|1|1]]></st_Cell21st_Bond6>

None;

<st_Cell42st_Bond9 quality="None" timeStamp="0001-01-01T00:00:00.0000000" type="xsd:string"><![CDATA[---|---|---|---]]></st_Cell42st_Bond9>

Thanks
