I'm trying to collect data from PLCs. Filemaker cannot read directly from them, but I can write a driver to get the data.

Question? How do I get the data into FM automatically. Does FM support ActiveX controls.

If not, are there some ODBC driver toolkits that I can use for custom driver development. Ultimately I would like to set up a data table in FM that stores the PLC addresses to read from, have the custom driver get the info from FM, then collect the data based on the addresses from the PLC, and transfer the retrieved data back into FM.

Any help would be greatly appreciated and would earn a Great Master of the FM Universe Title

FM does have ActiveX controls but they are very limited. Check out the FM help file under "ActiveX". You can basically open and close a FM file and a run a script. You can't transfer data in or out directly. You can if you maken an ODBC connection though. FM does have ODBC drivers.
