NBTOOL Variable

The installation and programming manuals indicate that this variable 
is read-only from the CNC, PLC and DNC.

Actually, it is read-only from the CNC and DNC and it can only be 
used inside a tool-change subroutine.

OPMODE Variable

This variable also returns the following code:

Probe canned cycle for surface measurement (PROBE 3)

The moving direction with K1 is as shown in this figure.

Connection of the KS50/55 adapter:

The installation manual describes how to use this adapter, but the 
correct connection is the following:
