Controlling an indexer with Fanuc Triac
I want to control a pneumatic indexer using M-codes from the Aux socket on this machine. The sequence would be signal out, indexer index to next position, signal back to machine to say indexer has indexed and then program continues. The index angle would be set on the indexer. The question is what signal do I get out of the AUX out and how can I use this to activate a relay or solenoid. When the indexer has finished how do I tell the machine to continue, ie what signal is it expecting for the aux in or wait for input 1.

Re: Controlling an indexer with Fanuc Triac
Hopefully the fanuc pmc logic in your machine has the CIM auxiliary I/O code in it, if it does then you can do it with a couple of M codes - one to turn Aux output 1 on, and then another to wait for Aux input 1 to go high (or low):
Auxilliary Output Functions.
M62 - Auxiliary Output 1 On.
M63 - Auxiliary Output 2 On.
M64 - Auxiliary Output 1 Off.
M65 - Auxiliary Output 2 Off.
M66 - Wait for Auxiliary Output 1 On. This M Code is executed at the end of a block, ie, after axis movement.
M67 - Wait for Auxiliary Output 2 On. This M Code is executed at the end of a block, ie, after axis movement.
M76 - Wait for Auxiliary Output 1 Off.
M77 - Wait for Auxiliary Output 2 Off.
These codes allow a signal to be sent from the machine controller to a different device, such as a robot, then wait for a return signal instructing that the device has completed its function.
