9.6 X81: Connection for external hand-held terminal
9.6.1 General information
Next to the inputs for the handwheel of the hand-held terminal (A, /A, B, /B), 12
inputs (IN0 – IN11) are available for the keys of the hand-held terminal. The keys
are supplied via the "+24 V" provided at the X81 plug.
The "+24 V" supply is internally generated by the supply "U
used to connect the keys of the hand-held terminal.
Connection "X81" for the hand-held terminal is located on the logic circuit
board.
The states of the inputs and the counter value of the handwheel are transmitted
to the master control via field bus.
