(*5) If “Program control Advance” is read, acknowledgement (data 0, MEWTOCOL) or Exception code 2 (02H, Modbus) will be returned.
If any value except 0001H (Advance Perform) is written, Error code 61H (MEWTOCOL) or Exception code 3 (03H, Modbus) will be returned.
(*6) If “Data clear” is executed, all values will revert to factory default values.
If communicating using parameters which are unequal to the factory default, it will be impossible to communicate. Set the communication
parameters again. (Refer to Section “3. Setting Communication Parameters”.)
If “Data clear” is read, acknowledgement (data 0, MEWTOCOL) or Exception code 2 (02H, Modbus) will be returned.
If any value except 1234H (Clear data) is written, Error code 61H (MEWTOCOL) or Exception code 3 (03H, Modbus) will be returned.
(*7) If “Key operation change flag clearing” is read, acknowledgement (data 0, MEWTOCOL) or Exception code 2 (02H, Modbus) will be returned.
If any value except 0001H (Clear key operation change flag) is written, Error code 61H (MEWTOCOL) or Exception code 3 (03H, Modbus)
will be returned.
(*8) Contents of error code are shown below.
Error Code Contents
Error 01 Non-volatile IC memory is defective.
Error 02 Data writing (in non-volatile IC memory) error when power failure occurs.
Error 05
Overscale:
PV has exceeded Input range high limit value (Scaling high limit value for DC voltage, current inputs).
Error 06
Underscale:
PV has dropped below Input range low limit value (Scaling low limit value for DC voltage, current inputs).
Error 07
Input burnout or disconnection:
Input value is outside of the indication range and control range.
Error 10 Hardware malfunction
Error 20 AT or AT on startup has not been completed even if approx. 4 hours has elapsed since starting.
For AT on startup, PV slope and delay time cannot be measured normally for P, I, D calculation.

(*10) Step 1 SV corresponds to SV1 (0001H) and SV1 (000EH).
(*11) Step 2 SV to Step 4 SV correspond to SV2 to SV4 (000FH to 0011H).
(*12) For TS1 OFF/ON time, TS2 OFF/ON time, and Steps 1 to 9 time:
Calculate the step time using the smaller time unit at Sep time unit, then convert it to hexadecimal numbers.
Use hexadecimal numbers for settings as follows.
Setting range 00:00 to 99:59 (0 to 5999) (e.g.) When ‘Hours:Minutes’ is selected in [Step time unit].
1:00 → 1 x 60+00=60 → 003CH
1:30 → 1 x 60+30=90 → 005AH
FFFFH: Step time is held, and Fixed value control is enabled.
(*13) Only when R0029 (AT/Auto-reset, AT on startup status) is ON (0001H), R002A (AT/AT on startup status) can be read.
When R0029 (AT/Auto-reset, AT on startup status) is OFF (0000H), and if R002A (AT/AT on startup status) is read,
acknowledgement (data is 0) will be returned.
