FX2N-64CL-M CC-Link/LT Master Block Assignment of I/O numbers 8
8-2
8.2 Example of I/O number assignment
This paragraph describes I/O number assignment in the configuration example shown below.
The CC-Link/LT master function for the FX Series checks connected remote stations in the
CONFIG mode. At the next power ON, this master function assigns the I/O numbers to each
connected remote station. RD stations do not give any effect on assignment of the I/O
numbers because buffer memories (BFM) are assigned to RD stations in accordance with the
station number.
Assignment result
*1 With regard to X and Y, 8 points are occupied as 1 block. As a result, if the number of I/O
points occupied by a station is a number which cannot be divided by "8", unused numbers
are generated.
In the configuration example above, the I/O numbers are assigned as shown below.
Station type Number of points I/O assignment (X) I/O assignment (Y) BFM #
Station No.1 Remote I/O station (input) 4 points X040 to X043 -- --
Station No.2 Remote I/O station (output) 2 points -- Y020, Y021 --
