Initialization
Initialization is performed prior to the first transmission/reception. The module is thereby parameterized with
the data from the corresponding Settings object.
Procedure:
1. Set "Init request" to 1
2. The module confirms successful initialization by setting "Init accepted".
3. Reset "Init request"
4. The module sets "Init accepted" to 0.
The module is now ready for data exchange.
Data transmission from the controller to the module (send 2 characters)
1. Set "Output length" to 2
2. Fill "Data Out 0" and "Data Out 1" with user data
3. Change the state of "Transmit request"
4. The module acknowledges receipt by changing the state of the "Transmit accepted" bit.
Data transmission from the module to the controller (receive characters)
1. The module indicates that there is new data in the process image by changing the state of the "Re-
ceive request" bit.
2. The number of bytes received is written in "Input length"
3. The controller acknowledges acceptance of the bytes by changing the state of “Receive request”.
