Serial
Data Unit
-
Features
1. Data input/output is executed by
Reading can be performed simply by using
high-level instruction F150 (READ), and writing by using
high-level instruction F151 (WRT).
Since the subsequent processing is performed by
the serial data unit through memory shared by the CPU unit, it is
not necessary to work out a complicated program.
2. Free combination of I/O devices
It is possible to use it in three ways: input
only, output only, and input and output
3. 500 bytes of data can be transmitted and
received at a time
4. No limitation on the number of units used
The number of units used is not limited.
This permits the connection of units in number
equivalent to 48 channels per CPU.
5. Can also be used as a C-NET master station.
The FP3/FP10SH can also be used as the data
collection terminal for our C-NET network.
