Using FINS Message Communications Section 6-3
Example 2: Sending a FINS Command Using CMND
Operation
• The PC with DeviceNet Unit 1 with node address 5 reads the data from
the 5 words D01000 to D01004 from the PC with DeviceNet Unit 2 with
node address 06.
• The MEMORY AREA READ command (01 01) is used to read variable
data.
• Command data is written starting from D01000 in the PC with De-
viceNet Unit 1 with node address 5 and the response data is written
starting from D02000.
• The completion code is stored in D00006 when execution of SEND
has been completed.
