5. LINKING TO AN ACPU AND AN AJ71 PT32-S3
MELSEC-A
ZAUTION
(1) Channels specified with *1 are used for executing read/write at addres-
ses 11
00
to 8099. They are automatically switched according
to the
remote terminal module station number designated
by the MELSEC-
NET/MINI-S3 dedicated instructions (hereafter referred to as the MINI-
S3 dedicated instructions).
(2) The buffer
is
completely cleared
(0
is stored.) at power ON, or when the
PC CPU is reset. However, the
retry count (address 1) and the NO-
PROTOCOL mode parameters (addresses
860
to 929) are set by
defaults.
(3) Do not write data from a PC CPU to read-only areas.
(4)
Unused areas are utilized by the system of the master module.
(5)
Data in the buffer (including unused areas) can be read continuously.
For example, data on accumulated faulty stations detection (addresses
90 to 93) and faulty station detection (addresses
100 to 103) can be
read by a single FROM instruction.
The AJ71PT3243 MELSECNET/MINI-S3 Master Module User's Manual gives details
on the
contents of each address and the data configuration of the buffer.
