HEIDENHAIN iTNC 530 HSCI - Module 9122 Status of PLC Axis

632 HEIDENHAIN Technical Manual iTNC 530 HSCI
Module 9122 Status of PLC axis
Request for PLC positioning status.
Module 9122 was expanded by bit 7. Bit 7 is only supported in positioning jobs
that were started with PLC Module 9227. During positioning with Module
9120, limit-switch monitoring as with Module 9227 bit 1 = 1 is not active.
Condition:
 Status changes through the PLC positioning command are not detected
until the next PLC scan.
