(5) Diagnostic function
Item
Error history data cannot be stored in the
Error history
memory card.
LED indication priority cannot be set. Only LED
LED indication priority
indication setting at error occurrence is
setting
supported.
(6) Debugging
Item
To use the monitor condition setting, the
Q10UDHCPU, Q20UDHCPU, Built-in Ethernet
port QCPU, or the modules (Q02UCPU,
Monitor condition setting Q03UDCPU, Q04UDHCPU, Q06UDHCPU,
Q13UDHCPU, and Q26UDHCPU) whose serial
numbers (first 5 digits) are "10042" or later must
be used.
Time required for executing a part of the
program cannot be measured using the scan
Scan time measurement
time measurement function.
To use the external input/output forced on/off
function, the Q10UDHCPU, Q20UDHCPU,
Built-in Ethernet port QCPU, or the modules
External input/output
(Q02UCPU, Q03UDCPU, Q04UDHCPU,
forced on/off
Q06UDHCPU, Q13UDHCPU, and
Q26UDHCPU) whose serial numbers (first 5
digits) are "10042" or later must be used.
* 1 Scan time of each program can be checked on the Program monitor list screen.
* 2 Device test can be performed when the modules (Q02UCPU, Q03UDCPU, Q04UDHCPU, Q06UDHCPU,
Q13UDHCPU, and Q26UDHCPU) whose serial numbers (first five digits) are "10041" or earlier are used.

Replacement method
The Universal model QCPU can store history
data by the number of storable history data in a
memory card (100) to the system memory.
---
Replacement method
Check device data under the specified
monitoring condition by using the sampling
trace function when using the Q04UDHCPU,
Q06UDHCPU, Q13UDHCPU, and
Q26UDHCPU. With this function, changes of
the specified device data can be recorded at the
following timings:
• at execution of the specified step
• on the rising/falling edge of bit devices
• when the value of word devices coincide with
the setting value
• at every specified time (settable range: 1 to
5000ms)
Calculate the time using instruction processing
time described in the manual.
Replace the function by using the programs
described in Page 551, Appendix 5.4.7 when
using the modules (Q02UCPU, Q03UDCPU,
Q04UDHCPU, Q06UDHCPU, Q13UDHCPU,
and Q26UDHCPU) whose serial numbers (first
5 digits) are "10041" or earlier. Note, however,
that replacement method described does not
apply in the following cases:
• Input and output targeted for forced on/off are
referred to or changed using the direct input
device (DX) and direct output device (DY).
• Input and output targeted for forced on/off are
referred to or changed within an interrupt
program.
