Controlling the handshake bit

Control of the handshake bit is recommended to check whether the data of the lower-level controller is still correctly received, processed and signaled. The following logic must be implemented on the higher-level controller for this purpose:

IF Handshake-Out = Handshake-In THEN

  invert Handshake-In

ELSE

  Time monitoring, with timeout error

END_IF

If the SBus^PLUS connection between the MOVI-C^® CONTROLLER and MOVI-C^® devices is interrupted, the inverted bit is transferred, i.e. the handshake bit OUT is "FALSE" if the handshake bit IN is "TRUE" and vice versa.
