CH1 Offset setting value
As Channel change request (Un\G70, b11) is turned offonoff in offset/gain setting mode, the measured temperature value
is corrected by a value written in this area.
Specify the value of a 16-bit signed binary number.
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
CH Offset setting value
CH Offset setting value (In FX2N allocation mode function)
■Setting range
Input type
Resistance temperature detector
*1
Thermocouple
*1 In the case of FX2N allocation mode, only thermocouple K, J and T are setting enabled.
Setting a value out of the range causes an offset/gain temperature setting value range error (error code: 1ECH).
'CH1 Offset setting value' (Un\G562) and 'CH1 Gain setting value' (Un\G564) must be set to be within the following
temperature input range:
• Offset setting value < Gain setting value
A channel where the set value is out of the above range causes an offset/gain temperature setting value setting error (error
code: 1E9H).
■Default value
The default value is set to 0.
• An effective way to achieve high accuracy is to set up error correction in 'CH1 Offset setting value'
(Un\G562) and 'CH1 Gain setting value' (Un\G564) assuming the minimum and maximum temperatures of
the used range.
• Configure 'CH1 Offset setting value' (Un\G562) and 'CH1 Gain setting value' (Un\G564) while reading out
digital output values.
