to high bytes in the response block.
The identity object information (class ID = 01 hex) is read from the other com-
pany’s EtherNet/IP node at IP address 192.168.250.2, using the CIP UCMM
MESSAGE SEND command, 28 10. The command data is stored in the DM
Area starting at DM01000, and the response data is stored in the DM Area
starting at D02000. If the command ends with an error, the end code is stored
in D00006 and command transmission is retried.
