22 Presentation, description Modicon M171/M172 logic controllers Communication modules for M171 performance and M172 performance logic controllers Presentation The communication module offer is dedicated to the 35 mm/ 1.38 in. rail mounting version of M171 performance and M172 performance logic controllers (1) . The 8 optional modules provide specific connections: b To fieldbuses, including: v CAN bus v Modbus TCP v Profibus v Modbus SL (RS 485) v BACnet MS/TP (B-AAC profile) v BACnet IP (B-AAC profile) v RS 232 serial link v LonWorks (FFT-10) v Konnex (KNX) via Schneider Electric' spaceLYnk gateway, Please consult on our web site b To services, including: v Ethernet v WebVisu and remote download functions b They are mounted by simple interlocking on the left-hand side of an M171 performance or an M172 performance logic controller (1). b Only one communication module can be added to a performance logic controller. The communication module is powered by the controller. b Each communication module has its own type of connector, adapted to the bus or communication network (see details in the reference table, page 23).
