4.1.2. Description of the bytes in the process representation input
Byte 1: Logic signals
Bits 3, 6, and 7 are collective signals.
Bits 5 and 4 of the logical signals (byte1) indicate a logical operation of the actuator,
i.e. they are set when the actuator has received the command to perform an electrical
operation (also active when e.g. the actuator is in a stepping pause during stepping
mode or waiting for the end of the dead time).
