Transmission setting for conditionally spontaneous messages
● Transmission criterion
Only configurable with: CP 1243-8 IRC / TIM 3V-IE DNP3 / TIM 4R-IE DNP3
With TIM 1531 IRC, the settings are transferred by the partner; if the send buffer
overflows, the "Degree of filling" setting is used.
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
– Degree of filling
– Time
– Time scheme
Time options
● Call acceptance delay
Only with CP 1243-8 IRC
Wait time (s) before accepting an incoming call
Due to the wait time acceptance of the call is possible for the TIM when a telephone is
connected to a shared telephone connection to the TIM.
Default setting: 0. Permitted range: 0...30

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
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.
The TIM sends conditional spontaneous messages at a configured time of day,
configurable with "Hours" / "Minutes".
The TIM sends the conditional spontaneous messages cyclically at a configurable
interval, configurable with "Hours" / "Minutes".
