Note
Power consumption
Note that frequent update and communication cycles increase the power consumption of the
RTU greatly. This applies in particular when permanently booked into the mobile wireless
network and when the LAN interface is activated often.
Update mode
● Basic cycle
From the drop-down list, specify the basic cycle (1 s .. 7 d) for updating the inputs and
outputs.
In every cycle, the RTU interrupts the sleep mode, reads the inputs, processes the
program blocks and updates the outputs.
● Start time of the update cycle
Synchronizes the update cycle with this time of day.
● Start day of the update cycle
Synchronizes the update cycle with this day.
The option is only available if "7 days" is configured as the basic cycle.
● Additional update cycles
Using the drop-down list you specify whether in addition to every configured basic cycle 1
to 3 additional update cycles are run through to execute the program. In the additional
cycles the program is executed.
Reading the inputs and setting the outputs does not take place in the additional cycles
but only after the basic cycle has elapsed.
If you select "0" only the basic cycle is used.
Communication mode
In the cycle configured here, the RTU activates all the interfaces and services used,
establishes a connection to its communications partner and sends all buffered messages
and files. In every cycle, the RTU interrupts the sleep mode.
You configure the communications partner on the WBM page "TeleControl". There you will
find further parameters for the transfer settings on the page of the protocol, being used.
A connection is always established by the RTU. With the DNP3 and IEC protocol the master
instigates connection establishment.
