Parity
Draft version 1.2.1 from 2017-09-13, valid from FW Version 02.06.20(09)
Explanation
Enable for the MODBUS RTU mode
*
Off Operation not permitted
Active Operation possible
Device ID (device address) for the tty device
*
1 min. device ID
247 max. device ID
Response timeout for a request in [ms]
2000 min. response time = 2 seconds. If this value is
set lower than 2 seconds, it will be corrected
internally to 2 seconds.
*
5000 Default = 5 seconds
4294967295 max. response time > 71 hours.
Device name
"dev/..." Name of the tty in the string
*
"dev/ttyO0" Standard tty

Number of stop bits
*
1 stop bit 1 stop bit in the frame; must be used when even
or odd parity has been selected.
2 stop bits 2 stop bits in the frame; must be used when
"None" has been selected for parity.
Parity check
None No parity check performed; 2 stop bits must be
selected in the configuration for this setting.
*
