On the machines that have the Embedded Ethernet option and have Focus drivers, you can use off the shelf solutions to collect the data. We have been working on a solution for years to pull data right off the controller and store into an SQL database (free SQL Express works too!). The cool part is the NC program #, part count, status, alarm and hundreds more points can be monitored from the ladder. Fanuc has their own software to do this but many DNC companies are providing this solution. The product we represent is called DataXchange and provides a low cost solution to monitor machines.
Mazak, Okuma, Mori and many others are jumping on board to use the network connection and use the MT Connect standard to capture this data. The solution can be written by the user or supplier of the machine to report in real time what is happening, and store historical data.
Not all shops will have the new machines with this capability, so use an inexpensive PLC to capture the data and report it all into the same database. There are reporting tools on the web (Crystal Report) that can make the "pretty chart/reports".
