A
Setting examples of message for Ethernet interface module
The following shows the setting example when using a command from an Ethernet interface module.
Examples of device access in ASCII code (3E frame)
The following shows the setting example when using a command for ASCII code and 3E frame.
■Device reading
• ASCII code, 3E frame
• Access target: QCPU of the connected station (host station)
• Command: Batch read in word units (command: 0401)
• Device: M100 to M131 (for 2 words)
1. Read values from devices.
Request message
*1 Monitoring timer (4 bytes) + Request data (20 bytes)
2. Receive the result.
Response message (Normal completion: Response data)
*1 End code (4 bytes) + Response data (8 bytes)
*2 The value of read data corresponds to the access target device as follows.
