tails.) The busy flag and present position status can be read out from the IN
refresh area, the last five of these words.
To start the Unit, set (i.e., turn ON) the command bit regardless of whether
the Unit is in RUN or PROGRAM mode. Do not shift the mode between
MONITOR and PROGRAM while pulses are being output. Doing so will gen-
erate an error, preventing Unit operation.
Example: Starting Unit #8 in MONITOR or PROGRAM Mode
START (command)
Start input
18000
In the above example, IR words 180 through 184 are allocated as the OUT
refresh area; IR words 185 through 190, as the IN refresh area.
Special I/O Unit
Restart Bits
AR Word 1
Restart bits can be used to transfer altered DM area data to the Unit without
turning power off and on. Refer to 6–3 Troubleshooting From the PC for re-
start bit allocations. The following Programming Console operation example
shows how to access the restart bit for Unit #0. The ladder diagram section
below it shows how to achieve the same operation through programming.

Data Configuration and Allocation
IR words 100 through 199 are allocated as I/O refresh areas. Each Position
Control Unit is allocated ten consecutive words. The first word for each Unit,
designated in this manual as n, can be computed from the unit number as
follows:
n = 100 + 10 x unit number.
Each Unit is also allocated 100 consecutive words as a fixed data area.
These words are in the DM area and run from DM 1000 through DM 1999.
The first word for each Unit, m, can also be computed from the unit number:
m = 1000 + 100 x unit number.
These allocations are shown below for all unit numbers. Details of allocations
within these words are given under the operations or commands to which
they apply. The tables on the following pages give a quick overview of word
and bit allocations. For a more complete overview, see Appendix C DM Area
Allocations and Appendix D IR Area Allocations.
