FC6 TM_TRANS2 The block transfers position and status information of the tools to the
tool management interface in connection with Multitool.
FC7 TM_REV The block acknowledges an implemented tool change of a turret to the
tool management interface.
FC8 TM_TRANS The block transfers position and status information of the tools to the
tool management interface.
FC9 ASUB The block starts asynchronous subprograms, the prerequisite is that it
must be selected and parameterized by an NC program or by the PI
service ASUP.
FC10 AL_MSG The block evaluates the signals entered in DB2, generates incoming
and outgoing error and operating messages of the operating software
and acknowledges error messages. Optionally, influencing of the
block and stop signals can commence.
FC12 FC12 Call interface for users for auxiliary functions, the block is called on an
event-driven basis in the basic program when new auxiliary functions
are available.

HT 2).
FC17 Ydelta The block is used for star-delta changeover for digital main spindle
drives.
FC18 SpinCtrl The block controls axes and spindles from the user program.
FC19 MCP_IFM The block is used for transferring data from the machine control panel
(MCP milling version) to the NC/PLC interface.
FC21 Transfer The block is used for high-speed data exchange between PLC and
NCK.
FC22 TM_DIR The blocks provides the shortest path and direction of motion for po‐
sitioning a tool magazine or turret (indexing axis).
FC24 MCP_IFM2 The block is used for transferring data from the machine control panel
(MCP milling version compact) to the NC/PLC interface.
FC25 MCP_IFT The block is used for transferring data from the machine control panel
(MCP turning version) to the NC/PLC interface.
FC26 HPU_MCP The block is used for transferring data of the HT 8 to the NC/PLC
interface.
FC1005 FC1005 Block transfers data to Ethernet CP.
FC1006 FC1006 Block receives data from Ethernet CP.
