Creating a Step

on New Protocol with the left button of the mouse.
2. Click
on New Sequence with the left button of the mouse and click on a blank space with the right button
of
the mouse.
3. Select
Create Step.
The
following table will appear. Set the parameters related to the step in the table.
Step
Step
number. The step number is automatically set.
Repeat
The
number (N) of times to repeat the step is set within a range from 0 to 255. It is possible to change mes-
sages
by making use of the number (N).
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.
Only
the Send & Recv command is used for communications with the 3G3RV except for broadcasting mes-
sages,
in which case the Send command is used.
Retry
Set
the number of times to retry the command within a range from 0 to 9.
It
is recommended that the number be set to 3 or larger. If a transmission error occurs due to noise, the trans-
mission
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.
For communications with the 3G3RV, if data is repeatedly transmitted to the same Slave, set the waiting time
to
20 ms or more.
Send Message and Recv Message
Set
the labels of the DSR message and response to be used.
Make
these settings after deciding the labels in Send Message Detail Settings and Recv Message Detail Set-
tings.
