Delta AS Series Programming Manual page 818

Example 3: Read the parameter of gain trim green channel on the first device of the second communication port.
1. Check HWCONFIG to learn the setting value in Ambient temperature is 28.60551.
2. AS04SIL is the first module that installed on the right side of the PLC CPU. The setting value in Group is 0, 1
Module and 2 in Port.
3. We learnt that its index is 268, its Sub-index is 0, and the data type is Float32T from its IODD file or the IO-Link
device manual. Set the setting values in Index to 268, in Sub-index to 0, in data type to 3 (Float32T).
4. Start sending "to read" request when M0 is ON. When M10 (DONE) is ON, it indicates the device has responded
and has complete reading. ReadLen (D40) is 4, and the data is stored in DataRead (D50~D51). IO-Link device
reads the data and stores it in accordance with the order of high byte and low byte.
