Response delay
Slave Ext
– As slave mode, except for the logging period, which in this mode is defined in the
Logging cycle
parameter (
).
– If the data from the master comes sooner than the set period, the data row will be saved
immediately to prevent data loss.
Spy
– The device listens in on the network via the RS2 interface. If it detects the response of another
device to master’s request, it performs logging of the response data.
– Logging the measured values of analog inputs is unavailable.
– The configuration in Spy mode is similar to the configuration in Master mode with the following
exceptions:
– The parameter
Query cycle
is not used, the period is defined by the Master. Thus,
Logging
cycle
should be adapted to the query cycle of the Master.
– If no data is received over the channel during
Logging cycle
, the string “
no data
” will be
written in the log row for this channel, the RS2 indicator will change to red.
–
Response time
parameter is not used.
