Product Details

EM277 Profibus DP Slave

Used to interface between a S7-22X CPU and a Profibus DP network
Can be simultaneously operated as MPI and DP slave
MPI protocol enables simultaneous data exchange with MPI masters
Allows an S7-200 CPU to be connected to a Profibus DP or MPI network as a slave, at various band rates up to 12 Mbaud. With the exception of the module address, which is set with 2 rotary switches, all other settings are in the DP master
In MPI mode, can be used to connect operator panels such as TD200 or TDO70
Maximum number of nodes - 31

Siemens Communication Module

The Siemens communication module is a highly efficient device that enables connection of SIMATIC S7-200 to PROFIBUS as DP slave module. It also enables communication with other S7 controllers based on the S7 communication medium. This module supports all standard baud rates from 9.6 Kbit/s to 12MBit/s. It has advanced features like diagnostic indicators and galvanic isolation that make it an ideal expansion module for various applications.
