6.3
Installation
Unlike the 9492/12 IS1 Ethernet socket, the 9496/32 socket of the IS1+ CPU is
connected to the slot (slot 0) on the BusRail. This moves all I/O modules by
one slot (slot n+1). Then the system has to be reconfigured! If there is space available,
a 9494/S1-B2 BusRail can also be connected at the beginning.
See also the IS1+ upgrade guide document.
Operation under difficult conditions, e.g. on ships in particular, requires additional
measures to be taken for correct installation, depending on the operating location.
Further information and instructions on this can be obtained on request from your
designated sales contact.
Devices connected to a company network or the Internet must be appropriately protected
from unauthorised access, e.g. by using firewalls or network segmentation.
All interfaces on the 9442/32 CPU module are designed to be intrinsically safe;
therefore, its connection lines can be plugged or unplugged safely during operation in
hazardous areas (hot swap).
