Frequently Asked Questions
Which serial standards are supported by 6ES7341-1CH01-0AE0?
Configure the isolated interface for the required RS422 or RS485 electrical standard.
What connector is used by 6ES7341-1CH01-0AE0?
The serial port uses a fifteen-pin Sub-D connector.
How fast can 6ES7341-1CH01-0AE0 communicate?
Select a supported rate from 0.3 to 76.8 kbit/s for the connected device and cable.
How long can the serial cable be for 6ES7341-1CH01-0AE0?
The point-to-point link can reach 1200 m when the configured standard, rate and cable meet the requirements.
What should be backed up before replacing 6ES7341-1CH01-0AE0?
Save the STEP 7 project, CP parameters, protocol, baud rate, parity, station role and application blocks.
Can an RS232 CP 341 directly replace 6ES7341-1CH01-0AE0?
No; the electrical interface and cable pinout must remain RS422/485.
What should be tested after installing 6ES7341-1CH01-0AE0?
Verify supply, port wiring, termination, send and receive data, protocol status and diagnostics.
Compatibility & Ordering Notes
Compatibility Checklist
- Use only with a supported S7-300 rack and STEP 7 configuration.
- Match the RS422/485 wiring and termination to the field device.
- Restore the protocol parameters and application communication blocks.
