PBUS Module 
 
Summarize 
 
PBUS makes SG2, which can’t work in ProfiBus DP network, to work in ProfiBus DP network. At ProfiBus DP 
side, PBUS mode is a gateway, a slave node in network. At PLC side, PBUS communicate with SG2 through SG2 
COMM. Port, it is point-to-point communication equipment. 
PBUS is together with SG2 as one slave equipment in ProfiBus DP network.
