STATES

Here follows the list of the available states.
SETUP state
The setup of the device is in progress. The encoder may not send commands to the
application in this state. If setup is successful, the module will shift to the
state; or, in case of failure, it will shift to the
NW_INIT state
The device is currently performing network-related initialization tasks. Telegrams now
contains Process Data (if such data is mapped), however the network Process Data
channel is not active yet. If the process is successful, the module will shift to the
WAIT_PROCESS
which prevents the system from proceeding), it will shift to the
WAIT_PROCESS
The network Process Data channel is temporarily inactive. The system will consider the
Read Process Data as not valid.
IDLE state
The network interface is idle. The Read Process Data may be either updated or static
(unchanged).
PROCESS_ACTIVE
The network Process Data channel is active and error free. Perform normal data han-
dling.
ERROR state
There is at least one serious network error. The Read Process Data shall be regarded as
not valid. Write Process Data could still be forwarded to the Master, so the application
must keep this data updated.
EXCEPTION state
The module has ceased all network participation due to an error. This state is unrecover-
able, i.e. the system must be restarted in order to be able to exchange network data.
