S100 I/O
S100 I/O are connected to the AC 800M, via the communication unit CI856. A bus
extension cable TK575/TK580, together with DSBC174/DSBC176 or DSBC173A,
connects the S100 I/O units to the base plate, TP856, of CI856. Up to five S100 I/O
racks can be connected to the CI856.
Redundant S100 I/O bus extension can not be connected to CI856.
S900 I/O
S900 I/O are connected to the AC 800M, via PROFIBUS DP and
CI854/CI854A/CI854B. The S900 I/O system is a remote I/O system for use in
hazardous areas. Due to its explosion protection certificates, the S900 process I/O
system can be installed in both hazardous areas (zone 1 and zone 2) and safe areas.
Other I/O Systems
A PROFIBUS DP segment (or node), shown on the top left-hand side of Figure 8 on
page 40, allows for a large increase in the numbers of units connected to each
AC 800M Controller. The segment is shown here with a Fieldbus Communications
Interface (FCI) unit (type CI840), connected to the PROFIBUS DP network. The
use of FCI units, or other types of adapters, allows the selection of units from
several I/O families.
