EXPLICIT MESSAGE SEND will send a DeviceNet Unit-compatible explicit
message to the specified class of another node and receive a response.

The other node is specified with the destination node address in the com-
mand. The actual destination IP address is as follows.

Destination IP address =

(Local IP address & Subnet mask)
+ Destination node address

The following response is returned if an error occurs for the explicit message.

The following response is returned if the explicit message cannot be sent or
times out.

The node address of the destination of the explicit message.

The node address of the local EtherNet/IP Unit or built-in EtherNet/IP port is
specified in the control data for the CMND(490), but the node address of the
actual destination is specified here in the FINS command. The destination
node address cannot be set to 00 hex or FF hex.

A service code defined for EtherNet/IP. In a normal response, bit 15 of the ser-
vice code specified in the command will be turned ON and returned. In an
error response, 94 Hex will always be returned.
