Notes: 1. If you change the flow rate engineering unit, affix the appropriate unit label (included with the MCF) on top
of the current label.
2. Does not function on RS-485 communications models.
3. Cannot be selected for RS-485 communications models.
4. Can be selected for RS-485 communications models only.

No. setting
C15 Analog alarm 00: Not used 00 For alarms such as sensor error or memory
output (Note 3) 01: Upper level (variable) error, the level of current set here is output.
02: Lower level (fixed) For these alarms, flow rate display is “0” while
an alarm occurs.
If “01: upper level” is selected, the analog
alarm output level can be changed in
maintenance mode.
If “02: lower level” is selected, the analog alarm
output level is fixed.
C30 Device address 00 to 99 00 There is no communication if the address
(Note 4) remains set at “00.” Set an address that is not
already being used by another unit.
C31 Transmission 00: No communication 02
speed (Note 4) 01: 19200 bps
02: 9600 bps
03: 4800 bps
C32 Communication 00: 8-bit data, Even parity, 00 For RTU, select “00” or “01” due to 8-bit data
conditions Stop bit 1 (RTU) processing.
(Note 4) 01: 8-bit data, No parities, For ASCII, select “02” or “03” due to 7-bit data
Stop bit 2 (RTU) processing.
02: 7-bit data, No parities, If RTU is selected, 8-bit data processing is
Stop bit 1 (ASCII) always applied even though “02” or “03” is
03: 7-bit data, No parities, chosen.
Stop bit 2 (ASCII)
C33 Communications 00: MODBUS (RTU) 00
type (Note 4) 01: MODBUS (ASCII)
