With parameter 157 it can be programmed as to whether the next tool number is output - or not - after output
of a tool number. Through cutput of the next tool number or next tool store number, a tool changing facility can
be brought into the required position.

With auxiliary function M92, tool change positions programmed in machine parameters 186 to 189 can be called-
up in relationship to the axis reference point.

If parameter 225 is programmed with a value 2 1, a tool list with 1 to max. 99 tools - with or without special
tools - can be defined under program number 0 within the memory of the TNC 35l/TNC 155-control.
If an automatic toolchanger is being used, it can be set-up for fixed tool selection or random tool selection,
depending on the entry of parameters 61 and 157. Operation of a toolchanger is supported by a PLC-macro-
program (see separate description).
If parameter 225 is programmed with 0, a central tool memory is inaccessible and the output of tool store
numbers via parameters 61 and 157 is inhibited. The tools then have to be defined within the individual
workpiece programs.
