AS-i 3.0 PROFIBUS Gateway with integrated Safety Monitor
Appendix: Example for startup on a Siemens S7
If this bit is set, the AS-i Master immediately switches to the offline phase and
stops AS-i communication when an AS-i configuration error is detected. This re-
sults in the connected AS-i output modules immediately switching to safe mode
(outputs turned off).
AS-i Configuration Mode
Bit 6: 0 = no action, 1 = turn on configuration mode of AS-i Master
Setting Bit 6 switches the AS-i Master to configuration mode. Then for example
the command interface can be used to save an existing AS-i configuration using
the controller.
The rising edge is used for switching. After Bit 7 = 1 in the input flags has indicat-
ed that the AS-i Master is in configuration mode, output bit 6 must be reset again
by the controller.
AS-i Protected Mode
Bit 6: 0 = no action, 1= turn on protected mode of AS-i Master
After successful configuration of the AS-i Master through the command interface,
the AS-i Master can be switched back to protected mode.
The rising edge is used for switching. After Bit 7 = 0 in the input flags has indicat-
ed that the AS-i Master is in configuration mode, output bit 7 must be reset again
by the controller.
The table shows an AS-i circuit which is in operation. Since there is no AS-i error,
bits 4 - 7 in the input byte are ZERO.
In the case of AS-i Slave address 1, this is a 4 I/O module. In this module
Output 3 is set and Input 1 allocated.
