Communication path - Diagnostics
The AS-i master enters the value of the I/O fault bit (S1) on the slave status tab in the list of
I/O faults (LPF) that have been signaled. The PLC can read out this list using the "GET_LPF"
command and then return a specific diagnostic value from the slave (see Diagnostics via
parameter channel) (Page 137)).
Slave diagnostics echo (parameter echo)
Bit P0 defines whether a fault diagnosis (P0 = 1) or warning/message diagnosis (P0 = 0) is
returned to the master as a slave response.
The "Write_Parameter" command (see the manual for the AS-i master) is used to send the
parameter value P0 (= 0 or 1) to the AS-i master and, therefore, to Slave 2. P3 is set by the
system, P1 and P2 can have any values.
