How to configure Port 2
Question
D0-05 (D0-06) I would like to create a communication program using port 2 of the CPU main unit.
I saw the user’s manual for D0-05 (D0-06), but I don’t understand how to set the communication conditions for port 2.
Answer
Method 1: Set with KPP (Kostac PLC Programming Software).
Method 2: Set communication conditions in the ladder program.
Please set by either method.
How to set with KPP
From the KPP menu, go to “PLC”->”PLC Setup”->”COM Port Setup”, switch the port to “Port2”, and set.
How to set in the ladder program
Set the parameters in R7655 and R7656 of the data register, and set the setting code 500H in R7657.
About base timeout time
The base timeout period depends on the communication protocol used.
K sequence: 800ms
DirectNET: 800ms
Modbus: 500ms
