Example 1
This section describes an example of user communication protocol settings for creating the following commands and
command operations.
• Transmission command for transmitting data using Constant (Hexadecimal), Constant (Character), Device,
Constant (Hexadecimal) command settings when the trigger condition device changes to 1
• Receive command for receiving, processing, and storing data in devices, using Constant (Hexadecimal), Constant
(Character), Device, Constant (Hexadecimal) command settings, for data transmitted from an external device,
when the trigger condition device is 1
■ User Communication Settings dialog box settings
■ Transmission command: Command Settings dialog box settings
Operation for transmission command
1 Write a value of 100 (DEC) to LDR100 of transmission command data Device.
2 Change the trigger condition LM100 from 0 to 1 to start command transmission.
After the transmission wait duration (five seconds), the transmission data is sent. The transmission data is as follows.
• When data transmission is successfully completed, the Completed Device LM101 changes to 1.
• When the value of each bit of address+0 for Status Device LDR110 is 0, transmission is completed without an error.
