7.5.4 Parameterization
Note
The mini HHU can only be operated with a Siemens machine control panel.
To address the mini HHU using standard addresses, set the following machine data:
MD12986 PLC_DEACT_IMAGE_LADDR_IN[6] = -1
If a mini HHU is connected, the functional assignment listed in the table below is valid for
customer keys KT1 to KT9. On machine control panels MCP 310C PN and MCP 483C PN,
the customer keys are assigned to input bytes IB122 and IB123. On the MC Interface PN
module, the customer keys are assigned to input bytes IB124 and IB125.
When the mini HHU is connected, the customer keys (inputs) are not available for other
applications.
