Hello.

Does anyone know how I can use the "WRITE TO PLC KEY" command on a TNC640?

What I need is to change the safedistance on the TT tool measurement probe.

On the TNC530 i used:
"FN 17: SYSWRITE ID 1000 NR6540 IDX0 =+5" for 5mm safedistance.

But how do I do this on the TNC640?

In the plc it looks like this:

CfgTTRoundStylus (
key:="TT",
centerPos:= [
0,
0,
0
],
stylusAxis:=Z_Positive,
stylusDimension:=22,
safetyDistToolAx:=5,
safetyDistStylus:=5

it is the "safetyDistToolAx" i need to change from the nc program

-regards

It is there. But I need to change it from the NC program. Not by entering the MP manually.

Machine parameters can be read in the NC program:
DECLARE STRING QS10 = "" ;no key name, global parameter
DECLARE STRING QS11 = "CfgTTRoundStylus" ;name of configuration object
DECLARE STRING QS12 = "safetyDistStylus" ;attribute name (= parameter)
Q1 = CFGREAD( KEY_QS10 TAG_QS11 ATR_QS12 )

The machine parameters can be overwritten only the PLC program... (Module 9430, 9432, 9433)
