8.6.3 Functions of the machine control panel
The machine control panel offers the following functions:
S Default
S Hand wheel
S Additional I/Os
The function transfers input/output data from the function keys and user–spe-
cific keys and outputs:
S Input data: 8 byte
S Output data: 8 byte
The input/output data for machine control panel MCP 310 is compatible with the
input/output data from the previous machine control panel OP 032S.
The function transfers the absolute values for the two handwheels that can be
connected to the machine control panel:
S Input data: 2 x 2 bytes
Absolute value handwheel 1
Low byte
High byte
Absolute value handwheel 2
For each handwheel the current handwheel value is transferred as a 16–bit ab-
solute value relative to the starting value. The starting value for the sensor
counter in the handwheel is 0.
The absolute values are transferred in big endian format.
