Sample Program Sample Program
This sample program uses the PLC C200HE made by the OMRON Corporation.
Construction of network: Master: 1 unit, AD-4402: 1 unit. The scan list is stored in the
scanner.
IN DATA: 350 to 357 ch
OUT DATA: 50 to 53 ch
Input module is installed in the slot 4th.
In this example, there are some unused data in IN DATA and OUT DATA.
Operation
When pressing the start button, a final value (1000) is set to material code (No.5) and
batch programming is performed.
Procedure of command is as follows:
1. Setting material code.
2. Inputting a final value.
