Restrictions for CS1-series PCs
Section 6-6
Method 2: PC READ@ or PC WRITE@
The addresses shown in the following table can be specified for PC READ@
or PC WRITE@.
Note
Other addresses cannot be accessed directly in CS1-series CPU Unit mem-
ory. Use methods 3 to 5 for other addresses.
Method 3: PC GET or PC PUT
There are no restrictions.
Method 4: Reading/Writing Shared Memory in ASCII Unit Using PC EGET/PC EPUT or IOWR/IORD #00
There are no restrictions.
Note
The number of read/write words for IOWR/IORD must be specified in hexa-
decimal for the CS1 Series.
Method 5: IOWR/IORD #FD00 and PC QREAD@/PC QWRITE@
There are no restrictions in the words that can be transferred and the words
specified for the IOWR/IORD #FD00 instruction will take priority, The
addresses specified for the PC QREAD@/PC QWRITE@ commands will be
stored in words n+8 and n+9 for monitoring by the CPU Unit. If addresses are
specified for IOWR/IORD #FD00 that cannot be specified for PC QREAD@/
PC QWRITE@, then use dummy addresses in PC QREAD@/PC QWRITE@.
The CPU Unit will not monitor the specified words when dummy addresses
are used.
Note
The number of read/write words for IOWR/IORD must be specified in hexa-
decimal for the CS1 Series.

Using the Sync Time Set Bit for CS1-series PCs
The clock (RTC) in the ASCII Unit can be changed to the time set in the Cal-
endar/Clock Area (AR 18 to AR 21) in C200HX/HG/HE CPU Units by turning
ON the Sync Time Set Bit (word n, bit 05). With CS1-series PCs, however, the
equivalent area (the Clock Data Area) is in words A351 to A354, so the clock
will not be set correctly even if the Sync Time Set Bit is turned ON. To enable
using the Sync Time Set Bit with CS1-series PCs, insert the following instruc-
tions into the program. (This requires that the ladder program is being exe-
