EM 277 Siemens Profibus DP Slave  6ES7 277 0AA22 0XA0 

EM 277 Siemens :

 6ES7 277 0AA22 0XA0 is used to interface between a S7-22X CPU and a Profibus DP network. EM 277 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. 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. Also it can be used to connect operator panels such as TD200 or TDO70 Maximum number of nodes – 31.
