I was asked to help install an automated clamping fixture to a new machine with a Fanuc controller. The fixture has a controlled actuator to adjust for the part depth, and also has an analog pressure sensor. So it's necessary to pass the part size to the fixture from the CNC program. I was thinking of a PLC with Modbus output for the stepper actuator and analog input. But it's kind of impossible to connect any PLC to a Fanuc controller! They have a proprietary I/O link interface only. OK, we contacted Fanuc for advice. And their advice was pretty short: contact our certified services only. So if you ever bought a CNC machine with a Fanuc controller - you're in slavery. Of course there are solutions but they cost a lot. And the service costs a lot too. Another story. I know an owner of a pretty complicated CNC machine with a Siemens controller, 20+ years old. The controller was not functional. The guy could not repair it for a very long time. No service wanted to deal with it! So he contacted the machine manufacturer. They said no problem, we can supply a brand new controller cabinet for the machine. Priced at $ 200K... oops! So he spent a lot of time and money until he found some guy who was able to repair the controller. So... beware those brand CNC controllers and interfaces. Just my 2 cents, anyways. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
