SAGE SEND command if it was completed normally.
The following response is returned if an error occurs in a transmitted CIP
UCMM MESSAGE SEND command.
The following response is returned if the CIP UCMM MESSAGE SEND com-
mand could not be sent or timed out.

toring time can be set between 0.01 and 655.35 s.
Service code (command, response):
In the command, this code is the service code defined for EtherNet/IP.
In the response, bit 15 of the service code specified in the command is turned
