Set this bit to enable external output of outputs #0 though #7. The status of the
outputs is shown on indicators 0 though 7 when outputs are enabled. Word n+9
status is output regardless of the condition of ENABLE OUTPUT.
Word n, bit 07
Setting this command bit enables usage of the output force bits in word n (bits 08
through 15).
Output Force Bits
Word n, bits 15 through 08
Output force bits can be set to turn ON outputs #0 through #7, thereby permitting
wiring checks. Both the ENABLE OUTPUT command bit and the ENABLE
FORCED OUTPUT command bit must be ON to use the output force bits. The
following procedure is used.
1, 2, 3... 1.
Make sure the start signal is OFF.
2.
Set ENABLE OUTPUT.
3.
Make sure all output force bits are OFF.
4.
Set ENABLE FORCED OUTPUT.
5.
Set the required output force bits.
Refer to 4-3-1 Data Allocation for the specific bit allocations.
CHANGE PRESET
Word n, bit 04
CHANGE PRESET is set to designate any preset other than #0. If CHANGE
PRESET is OFF when the start signal is set, the countdown will begin from the
value designated by preset #0, regardless of the contents of the preset desig-
nated by the preset number.
Preset Number
Word n+1, bits 15 through 08
The preset number is set to designate a preset counter value other then preset
#0. The number set in bits 15 through 08 is effective only when CHANGE PRE-
SET is turned ON before the start signal is turned ON.
Word n, bit 06
RESET COUNTER is effective when the internal reset bit is designated with
back panel DIP switch settings (Refer to 2-1 Switch Settings). RESET COUNT-
ER can be combined with control input IN1 or resetting is possible using only
control input IN1. Refer to 3-3 Counter Reset Conditions for details. Resetting
returns the counter value to 0 and turns OFF all outputs.
Word n, bit 01
TRANSFER DATA can be set to transfer up to 6 preset counter values to replace
any of presets #0 through #19. The new presets can then be used for count-
down. Data in the proper format must be prepared in consecutive words in the
PC through the PC program or the Programming Console. The parameters de-
scribed below are required to transfer data. These are followed by explanations
of the data format used to prepare data in the PC data area. Data transfer is initi-
ated on the rising edge of TRANSFER DATA and is completed at the next I/O
refresh. Completion can be confirmed with the transfer completed flag, bit 04 of
word n+4. Transfer should be executed only when the Counter Unit is not count-
ing. Execution during counting may cause incorrect outputs.
Word n+2
Indicates the first PC word from which data is to be transferred.
