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.
