Siemens SIMATIC ET 200iSP User Manual

Properties Bene󹪝ts
Redundancy of the IM
• With two IM 152-1PN (as of V1.0) on IO controller (e.g. S7-400H via PROFINET IO)
or
• With two IM 152-1DP (as of V2.0) on DP masters (e.g. S7-400H via PROFIBUS DP)
• With software redundancy
Redundancy of the Power Supply PS With TM-PS-B
Fieldbus communication
If an IM 152-1DP is used in the station, all modules of the station can communicate with all DP
masters that are compatible with the "DP" transfer protocol according to
the IEC 61784‑1:2002 Ed1 CP 3/1 standard (DP stands for distributed I/O).
2.2 ET 200iSP in the Hazardous Area
Properties of zones
Hazardous areas are classi󹪝ed into zones. The zones are distinguished according to the
probability of the existence of an explosive atmosphere.
The ET 200iSP can be used in hazardous areas (Zone 1/ 21, Zone 2/ 22) and in the safe area.
You can connect intrinsically safe encoders, actuators and HART 󹪝eld devices to the ET 200iSP
which may be located up to zone 0/ 20 and in the safe area. The sensors, actuators, and HART
󹪝eld devices must be certi󹪝ed for operation in the corresponding hazardous areas.
You will 󹪝nd an overview of the zone divisions in the following table:
Table 2-4 Classi󹪝cation of zones
Hazardous areas Explosion hazard Example
Zone 0/ 20 Long-term, frequent or permanent presence of ex‐
plosive gas or dust atmosphere
Within containers.
Zone 1/ 21 Infrequent presence of potentially explosive gas or
dust atmosphere
In the region of openings for 󹪝lling and
emptying.
Zone 2/ 22 Rare or short-term presence of potentially explosive
gas or dust atmosphere
Areas bordering on zone 1/ 21
