Transmission setting for conditionally spontaneous messages
●
Transmission criterion
Only for interfaces with the Network node type "Station" / "Node station".
The transmission criterion controls connection establishment for the transmission of
conditional spontaneous messages. This reduces the number of connection retries.
Range of values:
– Standard conditions
No connection will be established due to the existence of conditionally spontaneous
messages .
Only in the following cases will a connection be established to send conditional
spontaneous messages.
- Threatened overflow of the send buffer
- Connection establishment by the communications partner
– Degree of filling
The TIM only establishes a connection when the configured fill level of the send buffer
for conditional spontaneous messages is exceeded.
In the input box, enter the fill level (%) of the send buffer at which when exceeded the
TIM establishes a connection.
– Time
The TIM sends conditional spontaneous messages at a configured time of day,
configurable with "Hours" / "Minutes".
– Time scheme
The TIM sends the conditional spontaneous messages cyclically at a configurable
interval, configurable with "Hours" / "Minutes".
