High Speed Data trending and loging

I have an application where the customer is looking to trend and log to file, tag variables. The customer wants to log data every 0.5 seconds.

We have a Panelview 1500 and PC's available. I'm looking for either an ActiveX control or software app capable of this.

I've looked into the datastore active X but it is only capable of logging every seconds...I need to log faster.

Any ideas?

Hello,

PeakHMI can log to a database every 100 milliseconds.

From the help file:

Refresh rate


If the refresh rate is 0 (zero) a record will only be inserted via a script command or mouse command. If the refresh rate is 100 milliseconds or greater a record will be inserted at the configured refresh rate.

PeakHMI's web site doesn't really help much

It looks like its an HMI with datalogging and trending capabilities..

Right?

Hello,

It is a full featured HMI.

There is a trial/demo installer and a demo project for ODBC data logging.

EMail support if you need some help.

for reference i wrote a program in java that read 120 16 bit registers over modbus and write them to solid state disk, and then read the registers again. It was reading the PLC about three times a second. This was fast enough so I didn't try to make it faster.

Citect (ugh) could certainly log every .5 seconds.
