Intrinsically safe communication
Interfacing to the intrinsically safe PROFIBUS DP with transmissionrates up to 1.5 Mbit/s over the IM 152 interface module. The IM 152 communicates autonomously with the higher- level system (PLC or master system).
For I&M purposes (Identification & Maintenance), the IM 152 and the electronics modules have an electronic rating plate. It is also possible for digital process signals to be tagged with a time stamp.
The firmware of the IM 152 can also be upgraded with a plug-in SIMATIC Micro Memory Card (MMC) or via bus.
The IM 152 interface module and the PROFIBUS connector may be removed and replaced under hazardous conditions. With fault-tolerant solutions, up to two IM 152 modules can be configured redundantly.
