Setting Communication Specifications (RS-232C/422 - Non-procedure)
Important
- Use the same communication specification settings for the controller and the external device.
Note - During setting of communication specifications, input signals cannot be handled.However, the input status can be checked with [Confirmation].
Checking Communication Status (Non-procedure) - When data is output via serial communication, output is suspended while communication specifications are being set.
- On the Main screen, tap the [System] menu - [Communication] - [Serial] - [RS-232C/422].
The Serial window is displayed.
- Tap [Setting] to set communication specifications.
Item | Set value [Factory default] | Description |
---|
Interface | | Adjust to the PC communication specifications. |
Baud rate [bps] [Note 1] | - 2400
- 4800
- 9600
- 19200
- [38400]
- 57600
- 115200
| Adjust to the PC communication specifications. |
Data length [bit] | | Adjust to the PC communication specifications. |
Parity | |
Stop bit [bit] | |
Flow control | [OFF] | Flow control is not performed with software. If the time in which there is no response from external devices reaches the timeout setting time, a timeout error occurs and an error message is displayed in the window.The parallel interface ERROR signal also turns on. |
Xon/Xoff | Flow control is performed with software.Data is sent according to the Xon/Xoff codes from external devices. |
Delimiter | | Adjust to the PC communication specifications. |
Timeout [s] | 1 to 120 [5] | Set the time in which a timeout error will occur in seconds. |
[Note 1]: If a speed of [38400 bps] or higher is selected, effective communication cannot be guaranteed depending on the cable length because speeds of over 20 kbps are not defined in RS-232C standards.In these cases, set the communication speed at [19200 bps] or lower.
- Tap [OK].
The settings are confirmed and the Serial window closes.
