D19
– Transfer values to the PLC
This function may only be used with the permission
of your machine tool builder.
The
D19
function transfers up to two numerical values or Q
parameters to the PLC.
D20
– NC and PLC synchronization
This function may only be used with the permission
of your machine tool builder.
With the
D20
function you can synchronize the NC and PLC during
a program run. The NC stops machining until the condition that you
have programmed in the
D20
block is fulfilled.
SYNC
is used whenever you read, for example, system data via
D18
that require synchronization with real time. The TNC stops the
look-ahead calculation and executes the subsequent NC block only
when the NC program has actually reached that block.
Example: Pause internal look-ahead calculation, read current
position in the X axis
