SIMATIC NET CP 243-2 AS-i Master

C79000-G8976-C142/02

5.2.13 Set_Operation_Mode

Purpose of the Command

With this call, you can select between the configuration mode and the protected

mode.

In the protected mode, only AS-i slaves are activated that are entered in the LPS

and whose expected and actual configurations match, in other words when the I/O

configuration and ID codes of the detected AS-i slaves are identical to the

configured values.

In the configuration mode, all detected AS-i slaves (except for slave address “0”)

are activated. This also applies to AS-i slaves in which there are differences

between the expected and actual configuration.

The “OPERATION MODE” bit is saved permanently in the EEPROM, i.e. it is

retained following a startup/restart.

When changing from the configuration mode to the protected mode, the CP 243-2

is restarted (transition to the offline phase followed by switchover to the online

mode).

Note

If an AS-i slave with the address “0” is connected, the CP 243-2 cannot switch

from the configuration mode to the protected mode.
