List of Error Codes

The pulse input module stores an error code in a buffer memory area of the error channel when an error occurs during its
operation. In addition, the input signal (X) of the error channel listed below turns on.
To clear the error, turn on the output signal (Y) of the error channel listed below so that the error code stored in a buffer
memory area of the error channel is cleared. With this timing, the input signal (X) of the error channel listed below turns off.
The corresponding buffer memory area and I/O signals (X/Y) vary depending on the channel where an error has occurred.

Error codes of the pulse input module are classified as minor errors or moderate errors.
• Minor error: An error that occurs due to failure of programs such as a fault in execution timing. Each function can be
performed normally after the error cause is eliminated by reviewing programs. (Number in the 1000s + H)
• Moderate error: An error such as a hardware failure. The count operation does not continue. (Number in the 3000s + H)
The following table lists the error codes to be stored.

Description and cause
There is no error.
A value other than Interrupt resend request (0) and
No interrupt resend request (1) is set in Interrupt
factor generation setting [n].
 indicates the interrupt setting related to the error
as follows:
0: Setting 1 to F: Setting 16
A value other than Invalid (0) to Warning output flag
(5) has been set in Condition target setting [n].
 indicates the interrupt setting related to the error
as follows:
0: Setting 1 to F: Setting 16
A value other than All channels (0) to CH8 (8) has
been set in Condition target channel setting [n].

Action

Set Interrupt factor generation setting [n] to Interrupt
resend request (0) or No interrupt resend request
(1).
Set Condition target setting [n] to a value from
Invalid (0) to Warning output flag (5).
Set Condition target channel setting [n] to a value
from All channels (0) to CH8 (8).
Set CH Preset setting value for accumulating
count value to a value between 0 and 99999999,
and then set CH Counter reset request to Reset
request (1) to reset CH Accumulating count value.
(It is necessary to restart the count operation with
CH Counter reset request.)
Set CH Preset setting value for accumulating
count value to a value between 0 and 99999999,
and then set CH Counter reset request to Reset
request (1).
Set CH Comparison output selection to
Comparison output function invalid (0) or
Comparison output function valid (1).
Set CH Comparison output setting value to 0 to
99999999.
Set CH Moving average processing selection to
Sampling processing (0) or Moving average
processing (1).
