OMRON CQM1H-CPU61 PLC
OMRON CQM1H-CPU61 PLC
The number of resends and response monitoring time must be set by the user
in the FB communications instructions settings in the PLC Setup, particularly
when using function blocks from the OMRON FB Library to execute FINS
messages or DeviceNet explicit messages communications. The values set in
this PLC Setup for OMRON FB Library will be automatically stored in the
related Auxiliary Area words A580 to A582 and used by the function blocks
from the OMRON FB Library.
This setting determines how much of a
delay there will be from the detection of a
power interruption (approximately 10 to
25ms for AC power and 2 to 5 ms for DC
power after the power supply voltage drops
below 85% of the rated value) to the confir
mation of a power interruption. The default
setting is 0 ms.
When the power OFF interrupt task is
enabled, it will be executed when the power
interruption is confirmed. If the power OFF
interrupt task is disabled, the CPU will be
reset and operation will be stopped.
Set to 0001 to 7D00 to specify a minimum
cycle time. If the cycle time is less than this
setting, it will be extended until this time
passes. Leave this setting at 0000 for a vari
able cycle time. (Can’t be changed during
operation.)
This cycle time will apply to the program
execution cycle when a parallel processing
mode is used
This setting is valid only when bit 15 of 209
is set to 1. The Cycle Time Too Long Flag
(A40108) will be turned ON if the cycle time
exceeds this setting.
This setting determines the time units used
in scheduled interrupt interval settings.
(This setting cannot be changed during
operation.)—
These settings determine whether
data will be exchanged between the
specified Unit and the Special I/O
Unit’s allocated words (10 words/
Unit) during cyclic refreshing for Spe
cial I/O Units.
CQM1H-CPU61
Turn ON the corresponding bit to dis
able cyclic refreshing when the Unit
will be refreshed in an interrupt task
by IORF(097), several Special I/O
Units are being used and you don’t
want to extend the cycle time, or the
cycle time is so short that the Special
I/O Unit’s internal processing can’t
keep up.
(Special I/O Units can be refreshed
from the program with IORF(097).)
At start of
operation.
Note If Special I/O Units are not refreshed periodically (i.e., within 11 s) by the CPU
Unit, a CPU Unit monitoring error will occur. (The ERH and RUN indicators on
the Special I/O Unit will be lit.) If the PLC Setup is set to disable cyclically
refreshing Special I/O Units, use the I/O REFRESH (IORF(097)) or SPEICAL
I/O UNIT REFRESH (FIORF(225)) (FIORF: CJ1-H-R CPU Units only) instruc
tion in the user program to refresh them.
