Offset/Gain Setting Mode (Buffer Memory Addresses 22, 23: Un\G22, Un\G23); Ch Maximum Value/Minimum Value Storage Area (16Bit) - Mitsubishi MELSEC Q Series User Manual

3 SPECIFICATIONS

3.4.10 Offset/gain setting mode (buffer memory addresses 22, 23: Un\G22, Un\G23)

Un\G22 (Offset specification)
Un\G23 (Gain specification)
3.4.11 CH maximum value/minimum value storage area (16bit) (buffer memory addresses
30 to 37: Un\G30 to Un\G37)

(1) Specifies the channel to be adjusted for the offset/gain settings.
(2) The channel for which the offset is to be adjusted is specified in buffer memory
address 22 (Un\G22) and the channel for which the gain is to be adjusted is
specified in buffer memory address 23 (Un\G23).
(3) Although it is possible to set multiple channels at the same time, set the offset
and gain separately (buffer memory addresses 22, 23: Set either Un\G22 or
Un\G23 to 0). If both are set at the same time, an offset/gain setting mode error
(error code 500) occurs.
(4) See Section 4.6 for the details of the offset/gain settings.

For Q62AD-DGH, information of b2 to b15 is fixed at 0.
(1) The value in the maximum value/minimum value storage area (32bit) (buffer
memory addresses 62 to 77: Un\G62 to Un\G77) is converted and the result of
conversion is stored in 16-bit signed binary at each sampling processing.
(2) When setting the analog input range from 1 to 5V (Extended mode) or 4 to 20
mA (Extended mode), select the CH
area (32bit) (buffer memory addresses 62 to 77: Un\G62 to Un\G77).
(3) The stored values for all channels will be cleared to 0 when the operating
condition setting request (Y9) is set to ON and the setting is changed or when
the maximum value/minimum value reset request (YD) is set to ON.
(4) The maximum and minimum values of digital values converted by sampling
processing are stored even on a channel where averaging processing is
specified.
