Words Allocated in CIO Area
Section 4-2
4-1-4 Data Exchange Using the LR Area Words
General-purpose data is exchanged cyclically between user-set words in the
CPU Unit (e.g., in the CIO, WR, or DM Area) and the Customizable Counter
Unit’s LR Area words.
Note If the Load OFF Bit, A50015, in the CPU Unit is turned ON, the following
words will be turned OFF in the Customizable Counter Unit at the next I/O
refresh.
a) Words n to n+4 (CIO Area words transferred from CPU Unit)
b) Words m+10 to specified last word (DM Area words transferred from
CPU Unit)
c) LR 00 to specified last word (CPU Unit words transferred to LR Area
in Customizable Counter Unit)
If the RUN/STOP Command Bit is enabled (i.e., if word m bits 00 to 07 are
00 Hex), the RUN/Stop Command Bit (word n bit 00) will turn OFF and the
operation of the Customizable Counter Unit will stop.
If the RUN/STOP Command Bit is disabled (i.e., if word m bits 00 to 07 are
01 Hex), the following type of programming is required to turn OFF Cus-
tomizable Counter Unit outputs: Turn ON one of the general-purpose bits
in the allocated words in the CIO Area and when the bit turns OFF (as a
result of A50015 turning ON), use it in the Customizable Counter Unit to
turn OFF the outputs.
4-2 Words Allocated in CIO Area
4-2-1 Allocated Words
SR 230 to SR 239 (10 words) in the Customizable Counter Unit’s SR Area are
allocated to words in the Special I/O Unit Area in the CPU Unit’s CIO Area
(CIO 2000 to CIO 2959) according to the unit number (0 to 95) set for the
Customizable Counter Unit using the rotary switches on the front of the Unit.
The following table shows the relationship between the unit number setting
and the CPU Unit’s word allocations.
