4.3.10 Time-out settings
Master communication time-out
The master communication time-out specifies the elapsed time without
contact before communication with the master is considered to be lost.
This value is stored in database
register 188 . The default value is set to
20 s.
Note! The database value is given in number of "ticks" 255. One tick is equal to
278

s, and 255 ticks is equal to 71 ms. Thus the value stored in
database register 188 must be multiplied with 71 ms in order to obtain
the time-out value in number of seconds.
RTG Communication time-out
The RTG communication time-out is stored in database register 249 .
The default value is set to 60 seconds. This is the value which specifies
the time interval without contact before communication with the RTG is
considered to be lost.
