• 2stop: 2 stop bits
11. Baud Rate
Select the transmission speed (bps).
12. Sending (Send Delay Setting)
When Enable is selected, a delay until the beginning of transmissions (1 to 100 ms) can
be set.
• Master Station:
The delay will be included between execution of the MSG-SND function and the
transmission of the command.
• Slave Station:
The delay will be included between reception of a command by the MSG-RCV func-
tion and the transmission of the response.
Settings 13 through 18 specify the ranges of relays, registers, and coils that are checked
when a response is sent automatically after a request is received from the Master Station.
It is not necessary to make these settings when messages are not being transmitted between
the Master and Slave. Also, if a ladder logic program is being used that transmits responses
with the MSG-RCV function, the processing will be duplicated so the MSG-RCV function
will be disabled.
When the system defaults are used, responses are transmitted with the parameters set to the
ranges shown below.
13. Automatically Reception (Automatic Reception)
Specify whether to automatically respond to a query from the master.
14. Readout of Input Relay (Input Relay Read)
Sets the leading register number and range of input relays that can be read through gen-
eral-purpose serial transmissions. See Table 6.6 for settings.
15. Readout of Input Register (Input Register Read)
Sets the leading register number and range of input registers that can be read through
general-purpose serial transmissions. See Table 6.6 for settings.
16. Readout/Write-in of Coil (Coil Read/Write)
Sets the leading register number and range of coils that can be read/written through gen-
eral-purpose serial transmissions. See Table 6.6 for settings.
17. Readout/Write-in of Hold Register (Holding Register Read/Write)
Sets the leading register number and range of holding registers that can be read/written
through general-purpose serial transmissions. See Table 6.6 for settings.
18. Write-in width of Coil/Hold Register (Coil/Holding Register Write Range)
Sets the overall range of coils and holding registers that can be written.
