Device Status Words Address 0 to 15: Error/status/status result information
The Bits at Address 0 to 15 of the Device Status Words have the following functions:
Address
Data
type*
Item Content Data content
0 to 1 WORD Error code
Displays the currently occurring
error code.
0 to 128
2 to 3 WORD Warning code
Displays the currently occurring
warning code.
0 to 128
4 to 5 WORD
Number of remaining
buffers
Displays the number of status
results that can be buffered, if
handshake control is [Enabled].
0 to 10
6 to 7 WORD Checksum
Displays the current sensor
setting status using an arbitrary
5-digit integer.
0 to 65535
8 to 9 WORD Current program No.
Displays the current program
No.
0 to 31
10 to 11 WORD
Program No. during
judgment

counts.
0 to 32767
14 to 15 WORD Processing time

the latest judgment process.
0 to 10000
* WORD : Unsigned 16-bit integer
DWORD : 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 5-29)
y The first occurred warning code will be displayed.
“Warning code list” (Page 5-30)
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 5-34).
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 real-time
communication cycle setting.
