7-42
Repeat
The number (N) of times to repeat the step is set within a range from 0 to 255.
It is possible to change messages by making use of the number (N).
Note
In this example, the same message is sent to three Slaves with addresses different to each other.
Therefore, the number is set to 3 in word S + 1. The number of Slaves is specified by the operand.
Therefore, select
Channel
, use the Edit command to set
Data Address
to
Operand
, and set 0N +
1 in order to select word S + 1.
In the above table, “Reset” means that the repeat counter must be reset first in the step.
Command
Set the commands, such as Send, Recv, and Send & Recv.
Note
Only the Send & Recv command is used for communications with the 3G3MV except for sending
broadcast messages, in which case the Send & Receive command is used.
Retry
Set the number of times to retry the command within a range from 0 to 9.
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 3G3MV, 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 3G3MV.
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.
