Zero Set/Reset
8-9-1
Function Applications and Overview
The zero set function corrects the analog input value to be the zero point at a desired time. The zero
reset function resets the correction that is performed with the zero set function. Use these functions to
correct the zero points of analog input signals.
8-9-2
Details on the Function
When the zero set is executed, the analog input value at the point of execution is corrected to be the
zero point. At this time, the analog input value is 0.
When the zero reset is executed, the zero point correction is reset, and the analog input value returns
to the original value.
Execution Method and Check Method
Use I/O data to execute the zero set or the zero reset and check the execution status.
Refer to
7-1 Specifications of I/O Data
on page 7 - 2 for details on I/O data.
How to Execute the Function
Set the
£
Zero Set Execution bit in the Ch
£
Operation Command of I/O data to execute the zero
set or the zero reset.
Execution Status Check
You can check the zero set or the zero reset execution status with the Ch
£
Zero Set Executing bit
in the Ch
£
Executing Status of I/O data.
Description of Operation
The operations of zero set and zero reset are described below.
• When the Ch
£
Zero Set Execution bit is changed from
0
to
1
, the Ch
£
Zero Set Executing bit
changes from
0
to
1
and the zero set is executed. When the zero set is executed, the analog input
value is corrected to be the zero point. At this time, the analog input value is 0. (Refer to (a) in the
figure below.)
• When the Ch
£
Zero Set Execution bit is changed from
1
to
0
, the Ch
£
Zero Set Executing bit
changes from
1
to
0
and the zero reset is executed. When the zero reset is executed, the correction
is reset. At this time, the analog input value returns to the original value. (Refer to (b) in the figure
below.)
