Hello,

Do you know how to disable the property of Memory Size of Proprietary archive trend?

I found the setting in help docucment says set to zero then it is disabled. But the input value must be in range 1 to 32 in PcVue.Is the help document wrong?

Thanks.

BestRegards,
Mark

Hi Nicolas,

The customer wants PcVue to write historical data of trends to proprietary unit file every second.no need to buffer them.

Hi,

if you want to archive data every second you have to modify "period" property with value 1.

Buffer is just an internal buffer to avoid permanent access to hard disk.

Thank you Romain.

I recorded one trend by setting "period" with value 1,buffer with value 1. and have about 15-20 seconds delay.
