The parameter TBIT is reset by the IP247 after storing the position (UEBN) or on termination
(STOP) of the teach-in from FB164. In teach-in, various positions can be approached, e.g. in in-
cremental approach or in the JOG mode. The conditions explained for these modes also apply
to the parameter TBIT.
Mode - zero offset absolute (BA 12),
zero offset relative (BA 13),
clear zero offset (BA 14),
tool length offset (BA 15),
tool length offset off (BA 16) and
clear error (BA 17)
The parameter TBIT remains set until the mode is complete. These modes cannot be aborted.
6.2.7 Data Area Requirements
The standard function block FB164 works with data block DB164. It requires data words DW8 to
DW15 as its working area.
An axis data block must be specified using the parameter DBNR. This data block is used for the
following:
to store the monitoring values, checkback signals, M functions etc. read from the IP247,
for indirect assignment of parameters (DW1 to DW7) to the function block FB164 and
to store the data required for the mode to be started.
