The PLC Modules 9160 (status interrogation of temperature and I2t
monitoring) and 9168 (interrogate commissioning status) are further special
cases. If the expanded PLC module interface is active, these two PLC
modules generate an error message and can no longer be used in this case.
Please use PLC Module 9066 (status of HEIDENHAIN hardware) instead of
PLC Module 9160, and PLC Module 9065 (status of commissioning function)
instead of PLC Module 9168. The corresponding functions were added to PLC
Modules 9066 and 9065 with software version 340 49x-05.
A sufficient number of double words—matching the maximum possible
number of machine axes (entry AXISNUMBER in the OEM.SYS)—must be
reserved for saving the axis coordinates for PLC Modules 9040/9041 (read axis
coordinates). If you do not reserve sufficient memory area for the axis
coordinates, the subsequent memory area might be overwritten by Modules
9040 and 9041.
As the expanded PLC module interface also requires memory space for at
most 32 double words, you can simply reserve the memory area for 32 double
words as an alternative to the entry AXISNUMBER in order to prevent data
from being lost by overwriting the memory area.
