connection diagram
The ‘S2000M’ database storage is far less then ‘ARM Orion’ database. It prevents the
creation of backuping if system has more than 2048 alarm loops and 511 partitions. It is possible
to reserve the PC by several ‘S2000M’ consoles. One can connect only single console to the PC
RS-232 interface therefore it is necessary to convert RS-232 interface to the RS-485 interface by
means of ‘S2000-PI’ which several consoles are connected to. The consoles are connected to the
RS-485 interface line by their RS-232 outputs via ‘S2000-PI’ convertors. The devices are
connected to the RS-485 outputs of consoles.
Figure 7 displayes the way of connecting several ‘S2000M’ consoles to the computer. In
addition to the capability of several consoles the ‘S2000-PI’ convertors provides the galvanic
isolation between the PC and the console. When ‘ARM Orion’ reserving by several consoles the
system device number should not exceed 127 and all system devices should have unique
addresses. If the computer failes each console will control own connected devices, i.e, the system
will disintegrate to several unrelated subsystems.
For regardful reserving the consol configuration should correspond to 'ARM Orion' or
'ARM Orion Pro' one given by “Database Administrator” program. The structure and the names
of the zones and partitions should be the same in both configurations. The user names given for
the same password are to be identical.
It is recommended to to write the console configuration from the computer by means of
“Database Administrator” program.
