Activation
The function is activated by the "Prog. test contour" softkey. The NC then starts the
block search and switches the selected program in the current channel to program
test mode:
• The auxiliary functions of the part program are output from the NC to the PLC.
• No axis movements are executed.
If during the block search the NC finds one of the part program commands WAITE,
WAITC or WAITMC, the NC waits for the specified partner channels, irrespective of
the current mode of these partner channels (e.g., normal program execution,
program test, search via program test, etc.).
When the NC reaches the specified target block in the current channel, the NC
stops the block search and deselects program test mode; the auxiliary functions of
the target block are no longer output.
Dialog message
A dialog message appears as soon as all the channels involved in the current
search have exited program test mode. This message indicates that, depending on
the particular part program, Repos offsets may have been produced during the
search operation in the channels involved in the block search and will be retracted
by the NC through interpolation the next time it starts. You must acknowledge this
message.
Any Repos offsets (in the individual channels) can be traversed manually one by
one in JOG mode, before program execution is continued at the point in the
program reached by the block search by pressing the "NC Start" key.
Search configurations
"Block search in program test mode" supports the following configurations:
1. Block search in the currently selected channel
(the currently selected channel is the channel selected by the HMI)
2. Block search in the currently selected channel and in all channels in which
the same workpiece is selected as in the current channel
3. Block search in the currently selected channel and in all channels that are in
the same mode group as the current channel
4. Block search in all channels of the NC
Configurations 2 to 4:
No block search is performed in the other channels (in contrast to the current
channel); program test mode is active in the other channels until a stop condition
(e.g., WAITMC) is detected.
