The RUN State LED behaves according to LIT[04] for devices with Input data only:
RUN STATE State description
OFF INIT State
Blinking PREOP State
Single Flash SAFE Operational State
ON
OPERATIONAL State
Table 4 Run State Status
The AL Status register contains four Information Blocks:
AL State: contains the AL state of the device (INIT, PREOP, SAFEOP, OP)
Error Indication: gives the information if an error is detected
State Info: application specific information set by the slave (not supported by this encoder)
AL status code: this parameter indicates the actual state of slave device, the encoder sup-
ports partially error codes acc. LIT[01], please refer to Chapter 3.2.2.3.
2.3.2 Sync Manager
Sync Manager is responsible for the data transfer synchronization between ESC and Master. Data transfer
between master and ESC is done via DPRAM. The encoder supports two kind of Sync Manager buffer
modes:
3-Buffer Mode
1-Buffer Mode
The encoder manages the initialization of the Sync Manager operating Modes via XML file ob by the data
supplied by the encoders SII himself
