Transmission of the message is initiated by inverting bit 0 in byte
0 of the
HANDSHK_OUT
area.
The Transmit Object can be transmitted via the device parameters
of the DP/CAN coupler cyclically by means of a timer.
Cyclic transmission via the timer is triggered by inverting the bit
0 in byte 0 of the
HANDSHK_OUT
area.
A change of transmit data is activated on cyclic transmission only
by inversion of bit 0 in byte 0 of the
HANDSHK_OUT
area.
