Description
SIPLUS S7-1500CM PtP RS422/485 -40…+70 °C Start-up -25 °C with conformal coating based on 6ES7540-1AB00-0AA0 . Communication module for Serial connection RS422, RS485 Freeport, 3964 (R), USS, 19200 Kbit/s, 15-Pin D-sub socket 6AG15401AB007AA0_datasheet_en
Application of S7-1500 IO Modul CM PtP
Communication modules enable the connection with an external communication partner to exchange data. Comprehensive parameterization options make it possible to adapt the control flexibly to the communication partner.
Modbus RTU master creates a Modbus RTU network for up to 30 Modbus slaves.
The following communication modules are available:
- CM PtP RS232 BA;
communication module with RS232 interface for the protocols Freeport, 3964(R) and USS; 9-pin sub D connector, max. 19.2 Kbit/s, 1 KB frame length, 2 KB receive buffer - CM PtP RS232 HF;
communication module with RS232 interface for the protocols Freeport, 3964(R), USS and Modbus RTU; 9-pin sub D connector, max. 115.2 Kbit/s, 4 KB frame length, 8 KB receive buffer - CM PtP RS422/485 BA;
communication module with RS422 and RS485 interface for the protocols Freeport, 3964(R) and USS; 15-pin sub D socket, max. 19.2 Kbit/s, 1 KB frame length, 2 KB receive buffer - CM PtP RS422/485 HF;
communication module with RS422 and RS485 interface for the protocols Freeport, 3964(R), USS and Modbus RTU; 15-pin sub D socket, max. 115.2 Kbit/s, 4 KB frame length, 8 KB receive buffer
