I try to use it for a turning machine with a turret with 7 positions, each position have one input to the CNC. The question is: Can I with the 802C control the turret, e.g. select a tool and move the turret to the specific tool index? From the PLC program I can do this, but I expect some condition be crucial for the reliable functionment of the machine, like a tool_changed_ok, previuos to the next NC instruction. I can't find this variable either, NC -> PLC, PLC->NC. I now try to explain a little best, when I want a tool, e.g. tool 6 (T6), first I must know from the NC about this instruction (I don't know the variable of the NC->PLC) for the execution of the tool change cycle, once the cycle is running I think is necesary a PLC ->NC recognition when the turret cycle ends and before the next instruction (after the tool change) can be executed (I don't know the variable). thanks

When you start the tool cycle in the PLC you can set the V32000006.1 signal (Read in disable-which stop the NC program execution) and after you've made the tool change and everything is OK, you can then reset it. Good luck Nit

Respect to "launch tool cycle", I don't know what variable is setted when a tool change is executed in the NC such that I can use it for launch (execute) the tool cycle. So, I mencioned V25000001.4 like probable. really Thanks..
