SEND IO
(Send each change on the inputs/outputs)
Factory setting SEND IO = On
Activate the SEND IO if you require short reaction times to
each status change on the input or output of a NET station
(e.g. at 2I 02, 8Q 01, etc.). In addition to the cyclical data
transfer, the status change will be sent to all other NET
stations in a separate telegram.
NET stations without a circuit diagram send each status
change of an input or output, without taking the SEND IO
setting into account.
An activated SEND IO function will considerably increase the
number of telegrams on the NET and can slow down the
transfer of other user data.
h
An increase in the bus pause time means that fewer
messages (inputs, outputs, bit data, word data) are
transferred per time unit.
The reaction speed of all devices connected via the NET
depends essentially on the baud rate, the delay time and
the volume of transferred data.
You should therefore retain the proposed bus delay of the
multiplier 0!
SEND IO
å
h If you are using a high-speed counter (e.g. CH01) with
constantly changing input data in the circuit diagram of a
NET station, SEND IO should be deactivated for this
station. Otherwise the station changes at the counter
input will unnecessarily increase the number of telegrams
on the NET.
