■ Overview
The IM 152 interface module connects the ET 200iSP to the
PROFIBUS DP with intrinsically-safe RS 485-iS transmission
technology with transmission rates up to 1.5 Mbit/s. A redundant
connection is also possible. In this case the ET 200iSP is con-
nected via two interface modules to two redundant
PROFIBUS DP segments of a fault-tolerant automation system.
The IM 152 is plugged onto a special terminal module (to be or-
dered separately). The following terminal modules are available:
• TM-IM/EM60 terminal module for one interface module and
one electronics module (with screw-type or spring-loaded ter-
minals)
• TM-IM/IM terminal module for two interface modules (for re-
dundant PROFIBUS DP connection)
Tasks of the IM 152 interface module
• Connection of ET 200iSP to the intrinsically-safe
PROFIBUS DP
• Autonomous communication with the host automation system
• Preparation of data for the fitted electronic modules
• Saving of parameters of the electronics modules
• The IM 152 can assign a 20-ms time stamp to digital process
signals.
The maximum address space of the interface module is
244 bytes for inputs, and 244 bytes for outputs.
■ Design
The terminal module of the IM 152 (TM-IM/EM or TM-IM/IM) is
connected directly next to the power supply unit on the DIN rail.
The PROFIBUS DP connection of the IM 152 is made using the
standard Sub-D socket on the terminal module. The matching
connection element we provide is a special terminating plug with
selectable terminating resistance. The terminating resistance
must be activated on the last ET 200iSP station of each
PROFIBUS DP segment.
Hot swapping of the IM 152 and the PROFIBUS connector is per-
missible under hazardous conditions.
A terminating module is provided together with the IM 152, and
must be fitted at the right end of each ET 200iSP station following
the last electronics module.
The IM 152 has a slot for micro memory cards (MMC). The firm-
ware can therefore be updated either via the PROFIBUS DP or
using MMCs.
The PROFIBUS addresses can be set using DIL switches at the
front which are protected by a cover.
LEDs on the front of the IM 152 signal the supply voltage, group
faults, bus faults, the active IM with redundant operation, and the
operating state of the fitted power supply modules.
