3.7.1.1.5 Remote Connection via further SICAM RTUs Automation Unit(s)
For engineering there must be a logical connection to that automation unit, which is subject of
the engineering task. The both following cases are differentiated:
• Connection with a local automation unit (that one, to which a physical connection exists)
Note
A first initialization of the automation unit is only possible in this way.
• Connection with a remote automation unit that one, which can be accessed via a local au-
tomation unit; thereby, a continuous remote communication according to IEC 60870-5-101
or -104 is required)
