Technical Data of the InterfacesΒΆ
Interface standards
The serial interfaces RCOM and OPERATOR are designed according to the standards EIA RS-232 and EIA RS-485. Both interfaces can be operated in RS-232 or in RS-485 mode.
Technical data
| Serial interface standard | EIA RS-232 or EIA RS-485 |
| Interface connector | Pluggable 9-pole terminal block |
| Potential separation | Yes, from the CPU, 500 V DC |
| Serial interface parameters | Protocol interface configurable via PLC configuration. Preset configuration for debugging the terminal interface. |
| Modes of operation | Data exchange |
| Protocols supported | RCOM/RCOM+ |
The pin assignment of the serial interfaces RCOM and OPERATOR is identical to the serial interface COM1 of the AC500 CPUs PM57x, PM58x and PM59x.
