Omron C200HE User Manual

AR 16 provides the time allocated to servicing operating level 0 of the SYSMAC
LINK System and/or SYSMAC NET Link System during each cycle when a SYS-
MAC LINK Unit and/or SYSMAC NET Link Unit is mounted to a Rack.

AR 17 provides the time allocated to servicing operating level 1 of the SYSMAC
LINK System and/or SYSMAC NET Link System during each cycle when a SYS-
MAC LINK Unit and/or SYSMAC NET Link Unit is mounted to a Rack.

These times are recorded in 4-digit BCD to tenths of a millisecond (000.0 ms to
999.9 ms) and are refreshed every cycle.

A clock is built into the C200HX/HG/HE CPU Units. If AR 2114 (Clock Stop Bit) is
OFF, then the date, day, and time will be available in BCD in AR 18 to AR 20 and
AR 2100 to AR 2108 as shown below. This area can also be controlled with AR
2113 (30-second Compensation Bit) and AR 2115 (Clock Set Bit).

Thursday; 05: Friday; 06: Saturday)

30-second Compensation Bit AR 2113 is turned ON to round the seconds of the Calendar/clock Area to zero,

i.e., if the seconds is 29 or less, it is merely set to 00; if the seconds is 30 or great-
er, the minutes is incremented by 1 and the seconds is set to 00.

AR 2114 is turned OFF to enable the operation of the Calendar/clock Area and
ON to stop the operation.

AR 2115 is used to set the Calendar/clock Area as described below. This data
must be in BCD and must be set within the limits for the Calendar/clock Area
given above.

1. Turn ON AR 2114 (Stop Bit).

2. Set the desired date, day, and time, being careful not to turn OFF AR 2114

(Clock Stop Bit) when setting the day of the week (they’re in the same word).
(On the Programming Console, the Bit/Digit Monitor and Force Set/Reset
Operations are the easiest ways to set this data.)

3. Turn ON AR 2115 (Clock Set Bit). The Calendar/clock will automatically start

operating with the designated settings and AR 2114 and AR 2115 will both
be turned OFF.

The Calendar/clock Area and Bits are refreshed each cycle while operational.
