01 to 99: (private) protocol
01 to 31: (MODBUS) protocol (Note) “01” is displayed only when “private”
is changed to “MODBUS”.
Reference 3 | Transmission speed selection | |
range | ||
|
1200, 2400, 4800, 9600,19200 bps
Only 9600 and 19200 bps are available with the MODOBUS protocol.
(Note) “9600” is displayed only when “private” is changed to “MODBUS”.
Reference 4 | Character selection |

802 | 8 bits | Odd | 2 |
(Note) “8N1” is displayed only when “private” is changed to “MODBUS”.
Reference 5 Checksum selection range
: Checksum ON : Checksum OFF
(Note) No display appears for the MODBUS protocol.
From “ temporarily stored” to Reference 6 “stored”
Pressing ENTRY for each programming
executes temporary storing. Pressing DISP for 2 seconds or more executes storing and returns to the operation screen.
Reference 7 Returning to operation screen
If the screen returns to the operation
screen before pressing ENTRY , the parameter is returned to the parameter before programming.
