(2) MODBUS communication setting: Baud rate setting (SET6-4)
●
○
ON: 19200bps
OFF: 9600bps (Default)
●
○
(3) MODBUS communication setting: Parity setting (SET6-3)
●
ON: odd
○
OFF: even (Default)
●
* When the STOP bit setting is "2bit," parity is set to "None" regardless
○
of the setting of this switch.
●
○
(4) MODBUS communication setting: Stop bit setting (SET6-2)
●
Stop bit can be set (1 bit or 2 bit).
○
ON: 2bit
●
OFF: 1bit (Default)
○
(5) MODBUS communication setting: MODBUS communication terminal
●
resistance (SET7-4)
○
MODBUS communication terminal resistance can be set (Valid or
●
invalid).
○
Terminal resistance: 120Ω
●
Set the terminal resistances as necessary.
○
For MODBUS system, terminal resistances are necessary at the both
●
ends of communication line. (Total 2 terminal resistances)
Set the terminal resistances at the both ends to be valid and set the
○
terminal resistances other than at the both ends to be invalid.
●
ON: Terminal resistance valid
○
OFF: Terminal resistance invalid (Default)
●
○
* The switches from (1) to (4) are read at the time of power-on. Even if
