2)
Serial-S-Bus
protocol
(data, parity)
3) 6)
Supports the S-Bus protocol on serial
interfaces (RS-232, RS-485/422, USB,
modem) in master/slave operation.
Character mode
(MC0 to MC5)
4)
Sending of characters or texts via serial
interfaces, basis for the creation of own
protocols in the user program
Profi-S-Bus protocol
Data exchange with multimaster
communication between controllers. Also
allows access with PG5 programmer, SBC
OPC server or web browser
Profi-S-IO protocol
For the operation of the PCD3.T760. Allows
configuration and diagnostics.
Ether-S-Bus protocol
Data exchange with multimaster
communication between controllers. Also
allows access with PG5 programmer, SBC
OPC server or web browser.
Ether-S-IO protocol
5)
For the operation of the PCD3.T66x. Allows
configuration and diagnostics.
MPI
Multi-point protocol for data exchange with
other devices (SBC-xx7 controllers, HMI,
SCADA systems)
1) Requires the use of the programming cable PCD8.K111
2) Requires a corresponding configuration in the hardware settings
3) Requires an assignment of the port in the user program (SASI). For new applications, the data mode should
always be selected.
4) RS-485 with immediate release of the data line after sending the last character
5) In preparation
6) S-Bus parity master mode (SM1) not supported on ports 2 and 3 (from FW 010)
