Sending Explicit Messages
Response Block
Parameters
The following normal response is returned to a transmitted CIP UCMM MES-
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.
Transport ID (command, response):
When multiple CIP UCMM MESSAGE SEND commands are being sent, the
Transport ID identifies the commands. This Transport ID is returned
unchanged in the response.
Message monitoring time (command):
Specifies the monitoring time in 10-ms units, in order to monitor the time from
the point that the EtherNet/IP Unit or built-in EtherNet/IP port extracts the CIP
explicit message from this command until a response is received. The moni-
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
ON and the resulting value is returned.
