Mod. 9312 Change Machine Parameters In Current Machine Parameter File - HEIDENHAIN iTNC 530 HSCI Technical Manual

Module 9312 Change machine parameters in the current machine
parameter file
Module 9312 enables you to dynamically overwrite the values of the machine
parameters in the active machine parameter file and the run-time memory of
the system, or only in the run-time memory. For machine parameters defined
as numerical values, the new value can also be programmed as a string.
Conditions:
For numbers the values must be returned as an integer. The decimal point

is shifted by the number of possible decimal places. For example, if
MP910.0 is to be set to 100.12 mm, the transferred <MP value > must be
equal to 1001200. (4 possible decimal places lead to multiplication by
10,000).
For non-indexed machine parameters, zero must be programmed as the

index.
Once the NC program has started, the module operates only during the

output of M/G/S/T/T2/Q (strobe) change signals.
Depending on the changed machine parameter's type, the geometry is re-

initialized.
Not every MP can be changed by the PLC.

If a new value for a machine parameter defined as a numerical value is

programmed as a string, the value is converted to the decimal system (even
if the new value is programmed in the "$0004" or "%0000011111" format,
for example).
If the new values are immediately transferred after the modification of the

active machine-parameter file and the run-time memory (bits 1 and 2 not set
in the parameter "Mode"), the marker 4174 (first run after MP was changed)
is set.
If the new machine parameters are not transferred immediately, the new

values will become effective when the module is called again without bit 2
being set.
