Connection of
HEIDENHAIN
components
The main computer (MC 62xx), the controller unit (CC 61xx, UEC 11x) and other control components
(PLB 6xxx, MB 620) are connected to each other via the HSCI, the HEIDENHAIN Serial Controller
Interface.
Figure: Example of HSCI connections
The HSCI components are connected via special shielded HSCI cables adapted for the increased
demands of machine tool environments.
Terminating resistors are not required in the HSCI system.
HSCI inputs
and outputs
The HSCI slaves are connected in series to connector X500 of the MC 62xx main computer. Connector
X502 is always the HSCI input to the HSCI slaves and X500 the HSCI output to the next HSCI slave.
Attention
The HSCI connecting cable may only be installed in a protected manner (e.g. within the electrical
cabinet, cable ducts).

X 500
The MC 62xx also features a second, non-synchronized output to
which, e.g., the MB 620 may be connected.

Note
The last HSCI participant in the line detects its position automatically (X500 remains open) and
internally and independently closes the HSCI network.
