Communication specifications such as communication speed and IP addresses are set for serial interface (RS-232C/422 connection) communication.
Setting Communication Specifications (Ethernet - Non-procedure)
Setting Communication Specifications (Ethernet - Non-procedure)Important
- Before setting the communication specifications, set the "Serial (RS-232C/422)" communication module to "Normal" or "Normal (Fxxx method)", save the setting to the controller, and then restart the system.Setting the Start-up Status [Startup Setting]
- Use the same communication specification settings for the controller and the external device.
- If the operation mode (FZ3-9
/H9 only) is set to [Multi-line random-trigger mode], this setting is not supported for line 1.
Reference- 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.

The parallel interface ERROR signal also turns on.Xon/XoffFlow control is performed with software. Data is sent according to the Xon/Xoff codes from external devices.Delimiter- [CR]

[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 this case, set the communication speed at [19200 bps] or lower. - Tap [OK].The settings are confirmed and the Serial window closes.
