(3) CH Set value check code
When the set digital value is out of the setting range, the check code is stored.
For details on the digital value range check function, refer to the following:
• Digital Value Range Check Function ( Page 104, Section 8.11)
The following table lists the check codes.
Check code
000FH
00F0H
00FFH
The stored check code is not cleared even if the digital value falls within the setting range.
When Scaling enable/disable setting (address: 010EH, 020EH) is set to Enable (0), the scale-converted digital
value is the target for the check code. However, when the scale-converted digital value is out of the setting range,
a slight inaccuracy may be contained in the target digital value for the check code when the check code is stored
due to an operational error in the scale conversion.
When a value is set for CH Shifting set value (RWw6 to RWw9, RWw16 to RWw19), the value with the shifting
set value added is the target for the check code.
(a) Resetting set value check codes
The check codes can be reset in the following two procedures:
• Write the digital value within the setting range, and turn on and off Error clear request flag (RYA).
• Turn on and off Initial data setting request flag (RY9).
(b) Default value
The default value is Within the setting range (0000H).
(c) Device number
The device numbers of this remote register are as follows:
Remote register name
CH Difference conversion reference value
180
A digital value exceeding the setting range is written.
A digital value less than the setting range is written.
Digital values greater and less than the setting range are written.
For example, the check code 00FFH is stored when a digital value less than the setting range is written
after a digital value greater than the setting range is written and the check code is not reset.
