Omron SYSDRIVE 3G3JV User Manual page 170

Communications
Note It is recommended that the number be set to 3 or larger. If a transmission error occurs due to
noise, the transmission of the command will be retried. If the number is set to 3, an error will be
detected if the transmission fails three times.
Send Wait
The waiting time until the data is sent.
Note For communications with the 3G3JV, if data is repeatedly transmitted to the same Slave, set the
waiting time to 20 ms or more.
In this example, the DSR message is sent to Slaves 1, 2, and 3 one by one. Therefore, no send
wait time is set.
Send Message and Recv Message
Set the labels of the DSR message and response to be used.
Note Make these settings after deciding the labels in Send Message Detail Settings and Recv Mes-
sage Detail Settings.
Response
Determine whether or not to write the reception data in the response.
Note Always set this parameter to Yes for communications with 3G3JV.
Next
Determine which step is to be processed next or finish the operation after the step finishes normally.
Note In this example, step 00 is set to Next and step 01 is set to END because the sequence completes
by executing steps 00 and 01.
Error
If the step has an error, determine which step is to be processed next or finish the operation.
Note In this example, the parameter will be set to Abort to interrupt the sequence if an error occurs.
