AS-i 3.0 Command Interface 1 Introduction Introduction The AS-i gateways integrate the AS-i slaves into the upstream fieldbus. Each upstream fieldbus (f.e. Modbus/TCP, CANopen, or PROFIBUS) has its unique possibilities to access cyclically and acyclically data. The gateway polls as an AS-i master all the slaves on the AS-i circuit. The result of these polls the gateway keeps in its internal state RAM as images of the inputs, outputs, parameters, and status.

AS-i 3.0 Command Interface 2 Structure of the Command Interface Structure of the Command Interface The command interface has the following structure shown in table 1 and table 2. Table 1 command request byte 27 26 T O 25 1 2 24 23 22 21 20 command circuit 3 request parameter byte 1 … … 36 request parameter byte 34 Bit T in the command interface is the toggle bit. The toggle bit is only necessary in the case of interfaces which transfer the data cyclically.

AS-i 3.0 Command Interface 4.7.3 Commands of the Command Interface Setting of the AS-i diagnosis The function unsorted diagnosis is available only with monitors in the version 2.0 and higher. The function sorted diagnosis is available with all monitors. The setting of the AS-i diagnosis takes place in the window "Information about monitor and bus" of the configuration software asimon for the AS-i safety monitor. • Call up the menu Edit/Information about monitor and bus Fig. 1.

PAGE 67
AS-i 3.0 Command Interface 4.7.4 Commands of the Command Interface Enhanced diagnosis Since the "Safety at Work“ monitor diagnosis is longer than the maximum size of the command interface, it must be read with several adjacent requests. The byte 5 (‘index’) declares the start index in the array of diagnostic data. If this start index is 0, the whole diagnosis is fetched from the monitor and stored to an internal buffer. Otherwise, the AS-i Master will respond out of the internal buffer.
