Practical Example 2
This program executes the same control as practical example 1 shown earlier from one communication port
(ch1) to two inverters (Station number: 0 and 1).
10.2.1 System configuration example
An FX PLC (ch1) is connected to two inverters (Station number: 0 and 1).
10.2.2 Contents of operation
Differences from the practical example 1 are the following three points:
• The PLC executes communication from one communication port to two inverters.
• Status is not being read when a write to inverter command is given.
• The PLC only writes when it detects that contents to be written have changed since last being written.
