Siemens SINUMERIK 840D sl TCU 30.3 Equipment Manual page 71

If a static.ini of the TCU to be replaced (as of SW4.5) is found on the server, then the type
of the old TCU is preselected based on the HW ID found there. If this is not the case, the
TCU20.2 type is selected.
The following TCU types can be emulated:
• TCU
• TCU 20.2
• TCU 30.2
Note that if an older TCU is to be replaced by a TCU30.3, some interfaces cannot be used
when the HMI version is older than V4.7. The following interfaces are affected:
