The filter output of each data port is preset to “0” after reset or as long as the Data_Exchange_Disable flag is

set, respectively.

Activation of Delay Mode depends on the E²PROM flags Delay_Mode and P1_Delay_Activation and the value

of the Parameter Port P1 Output Register as shown in Table 22. Delay Mode cannot be activated when Safety

Mode is enabled.

Note: The input signal at Parameter Port P1 does not influence activation of Input Delay Mode at all. Only the

master can change the activation status by sending a corresponding Write_Parameter (WPAR) request.

Synchronous Data I/O Mode

Since the slaves in an AS-i network are called successively by the master, the data input and output

operations of different slaves are not synchronized normally. If there is, however, an application that requests

accurate synchronized data I/O timing, the respective slaves may be operated in the Synchronous Mode.

Concerning the communication with the master, slaves running in the Synchronous Mode behave like regular

slaves. However, the input data sampling as well as the output data driving is determined by the polling cycle

of the respective AS-i network as described below.

Activation of the SAP5 Synchronous Mode is related to the E²PROM flags Synchronous_Data_IO and

P2_Sync_Activation (refer to Table 9) and the value of the Parameter Port P2 Output Register as follows:

NOTE: The input signal at Parameter Port P2 does not influence activation of Synchronous Data I/O Mode

at all. Only the master can change the activation status by sending a corresponding Write_Parameter

(WPAR) request.
