Serial Data
Unit
-
Features
1. Data input/output is executed by ladder
program command
Reading can be performed simply the subsequent
processing is performed by using high-level instruction F150
(READ), and writing by using F151 (WRT).
Since 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.
5. Can also be used as a C-NET master station.
The FP2/FP2SH serial data unit can also be used as
the data collection terminal for our C-NET network.
Regarding selection
When a display panel or computer that supports our
protocol operation display panel is connected, use the Computer
Communication Unit on the next page or the COM port of the CPU
unit.
