MSC station
You use this option for the TIM 3V-IE in a station.
The remaining MSC configuration is done in the SINAUT configuration tool. You will find
an overview of MSC configuration in the section
GPRS / Internet communication:
Overview of configuration (Page
15).
●
Send conditional messages as blocks
Data transmission over a GPRS network is subject to fees depending on the amount of
data transmitted. To minimize costs, smaller data packets can be collected and
transferred in larger blocks if these messages are assigned the "conditional" priority; in
other words, they do not need to be sent immediately, refer to the SINAUT software
TD7onTIM, section
Basic parameters of the data objects (Page 138) or the description
"SINAUT TD7 software package for the CPU" > "Data point typicals".
If the
Send conditional messages as blocks
option is enabled, the TIM transmits
"conditional" messages in the following situations:
– When the collected messages reach or exceed a size of 202 bytes.
– If an important message needs to be transmitted immediately, "conditional
spontaneous" messages already in memory are transmitted along with it.
– If the collected messages have not reached a size of 202 bytes, but the TCP/IP
keepalive interval has elapsed, the stored messages are sent instead of the keepalive.
– If messages are sent via an MSC connection, conditional spontaneous messages are
collected until 1 300 bytes have been reached or until an unconditional spontaneous
message is transmitted.
1.5.7 "WAN Access" tab
WAN Access
tab
In the
WAN Access
tab, you can configure the following WAN interfaces of the TIM modules
of types TIM 3 and TIM 4. The parameters correspond to the WAN parameters of the
Interfaces
tab for the Ethernet TIMs:
● The internal interface that is normally assigned to a modem installed on the module
● The external interface that must be set up by the user by selecting the required network
type and clicking on the
New...
button
Behind each interface that is to be connected with a network, there must be a network node
of the corresponding type and this can be recognized by the
Properties
button being
available for selection.
