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 Address,
Constant (Hexadecimal) command settings when the trigger condition device address changes to 1
• Receive command for receiving, processing, and storing data in device addresses, using Constant (Hexadecimal),
Constant (Character), Device Address, Constant (Hexadecimal) command settings, for data transmitted from an
external device, when the trigger condition device address is 1
■ Settings in the User Communication tab on the Project Settings dialog box
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 Address.
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 Address LM101 changes to 1.
• When the value of each bit of address number+0 for Status Device Address LDR110 is 0, transmission is completed
without an error.
