Explanation:
Unconditional spontaneous data transfer
With the two parameters "Conditional" and "Unconditional" you decide whet
h-
er a
data frame is transferred immediately by the module if the value changes
(unconditional spontaneous) or at a later point in time (conditional spontan
e-
ous).
The two parameters are programmed as follows:
•
Conditional spontaneous transfer (not necessarily immediately)
– Conditional = TRUE
– Unconditional = FALSE
•
Unconditional spontaneous transfer (immediately)
– Conditional = FALSE
– Unconditional = TRUE
The default of the two parameters was chosen so that a data frame is not
transmitted immediately.
The decision wheth
er a data frame is transferred immediately or later only
relates to dial
-up networks.
In a dial
-up network you must decide from case to case whether a change to
the value of the data point requires immediate transfer and therefore the i
m-
mediate establishme
nt of a connection. This can, for example, be required for
data points with alarms.
On a dedicated line, the transmission is always immediate even if the comb
i-
nation of "Conditional" and "Unconditional" is set to "not immediately". On
dedicated lines, you
do not need to make changes to the two parameter set-
tings.
