Modbus TCP and TCP/IP are supported. The base units PNOZ m B1 and PNOZ m B1 Burner of the configurable small controller PNOZmulti 2 have Modbus TCP and TCP/IP on-board.
The base units of the safety system PNOZmulti Classic, such as the PNOZ m1p ETH or the communications module PNOZ mmc1p of the compact controller PNOZmulti Mini also support these Ethernet interfaces.
Note: many Siemens controllers support the TCP/IP protocol (provided a PROFINET interface is present). This enables a connection to be implemented without an additional fieldbus module.
