HEIDENHAIN iTNC 530 HSCI - Sequence for finding serious electrical errors

56 HEIDENHAIN Technical Manual iTNC 530 HSCI
PLC modules Some PLC modules that return an error code to the PLC program via the PLC
program stack (PL command) did not influence the error word W1022 if an
error occurred (marker M4203 set). The value in W1022 remained unchanged
at a previous value. The PLC modules affected will be modified with this NC
software version and will also write to word W1022 in the future. As a result,
all PLC modules will have the same behavior and will transfer an error code in
W1022. You can then evaluate M4203 and W1022 in order to display an error
message. The following PLC modules are affected by this change:
 PLC Module 9031 – Overwrite machine parameter
 PLC Module 9032 – Read machine parameter
 PLC Module 9084 – Display PLC error message with additional data
 PLC Module 9090 – Select a line in the pallet table
 PLC Module 9092 – Search for an entry in the tables selected for execution
(.T/.D/.TCH)
 PLC Module 9095 – Select active line in configuration file
 PLC Module 9220 – Renewed traversing of the reference marks
 PLC Module 9221 – Start a PLC positioning movement
 PLC Module 9223 – Free rotation
 PLC Module 9227 – Position auxiliary axes and NC axes
 PLC Module 9281 – Select a line in the pallet table
 PLC Module 9310 – Change machine parameters in the current machine-
parameter file
 PLC Module 9312 – Change machine parameters in the current machine-
parameter file
 PLC Module 9313 – Read machine parameter
Information on the individual, new values for W1022 can be found in the
respective module description in the Technical Manual.
In rare cases this modification can influence the behavior of the PLC program.
HEIDENHAIN recommends:
Note
 Test the behavior of the PLC program on the machine.
 If the modification of word W1022 causes problems, you need to adapt
your PLC program to the new behavior.
