 D2：Error flag
 D3：Error code
 D4：Read data size
 D5：The start device where data are read.
 Program Explanation
 When M0 changes to ON, execute the explicit message instruction DNETRW to read Class 1 >> Instance
1 >> Attribute 1 of the target equipment with node ID: 01. If the explicit message communication succeeds,
the completion flag M1 changes to ON.
 When M0 changes to ON, AS01DNET-A sends out the request message only once. If the request
message is to be resent, the instruction DNETRW need be re-triggered.
 If the data reading succeeds, the content of Class 1>> Instance1 >> Attribute 1 of CMC-DN01 will be
stored in D5. In this example, the content in D5 should be 031FHex.
 Application Example 2
Control requirement: When M1 changes to ON, set the content of Class ID: 0x05>> Instance 1>>Attribute ID:
09 of CMC-DN01 to 000AHex.
