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.

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.
