Input Assembly Address 8 to 23: Error/status/status result information
The Bits at Address 8 to 23 of the Input Assembly have the following functions:
Address
Data
type*
Item Content Data content
8 to 9 UINT Error code
Displays the currently occurring
error code.
0 to 128
10 to 11 UINT Warning code
Displays the currently occurring
warning code.
0 to 128
12 to 13 UINT
Number of remaining
buffers
Displays the number of status
results that can be buffered, if
handshake control is [Enabled].
0 to 10
14 to 15 UINT Checksum
Displays the current sensor
setting status using an arbitrary
5-digit integer.
0 to 65535
16 to 17 UINT Current program No.
Displays the current program
No.
0 to 31
18 to 19 UINT
Program No. during
judgment
Displays the program No. of the
latest judgment process.
0 to 31
20 to 21 UINT Result No.
Displays the judgment process
counts.
0 to 32767
22 to 23 UINT Processing time
Displays the processing time of
the latest judgment process.
0 to 10000
* UINT : Unsigned 16-bit integer
UDINT : Unsigned 32-bit integer
y The unit of processing time is msec.
y If two or more errors are occurring at the same time, the error code of the highest priority error will be
displayed.
“Error code list” (Page 3-22)
y The first occurred warning code will be displayed.
“Warning code list” (Page 3-23)
y A checksum can be used to monitor whether the sensor settings have been modified by a third party.
y The checksum will remain unchanged even if you switch programs.
y The checksum will remain unchanged even if you change the IP address, subnet mask, default gateway
or port number of the IV series.
y For the number of remaining buffers, refer to “Reading out the overall status result of the IV series
(Handshake control [Enabled])” (Page 3-28).
y The upper limit value of the result No. is 32767. If the maximum value is exceeded, it will go back to 0
and start counting up again.
y The result No. will also count the judgment process counts that were skipped due to the cyclic
frequency setting.
