12.3 I/O Allocation
Item
No. of I/O points per one I/O link unit
Remote I/O map allocation
Note1) When setting the output of the I/O link error flag to ON (available), it is 63 points (31 input points
& 32 input points).
12.3.1 I/O Numbers
The example below shows a remote I/O system which one I/O link unit is connected to a FP0 control
unit.(When the I/O link error flag is off (unavailable))
The I/O link unit is recognized as a salve station with 64 I/O points (32 input points & 32 output points
(32X/32Y)) by the master unit of FP2/FP2SH/FP3/FP10SH.Therefore, the I/O number of the I/O link unit
from the FP2/FP2SH/FP3/FP10SH is determined by the base word number of the master unit connected
to the I/O link unit and the station number of the I/O link unit.
Also, in the remote I/O map, input is allocated first.In the above example, when connecting the I/O link
unit with the station number 1 to the master unit with the base word number 64, the I/O link area is
WX64 and 65 (X640 to 65F) for input, and WY66 and 67 (Y660 to 67F) for output from the
FP2/FP2SH/FP3/FP10SH.Also, when connecting the I/O link unit with the station number 2 as above,
the I/O link area is WY68 and 69 (X680 to 69F) for input, and WY70 and 71 (Y700 to 71F) for output
from the FP2/FP2SH/FP3/FP10SH.
The I/O numbers of the I/O link unit from the FP0 will vary depending on the installed position.
For example, if Y20 of the FP0 with the station number 1 is turned ON, X640 of the
FP2/FP2SH/FP3/FP10SH will be ON.If Y660 of the FP2/FP2SH/FP3/FP10SH is turned ON, X20 of the
FP0 with the station number 1 will be ON.Similarly, if Y20 of the FP0 with the station number 2 is turned
ON, X680 of the FP2/FP2SH/FP3/FP10SH will be ON, and if Y700 of the FP2/FP2SH/FP3/FP10SH is
turned ON, X20 of the FP0 with the slave station number 2 will be ON.As above, the I/O link unit is able
to exchange the I/O information between the FP2/FP2SH/FP3/FP10SH and FP0.
