Setting Items
- [Connection] (1 : 1 / 1 : n / Multi-Link / Multi-Link 2)
Select the type of connection between the V7 series and the PLC. There are four
types available. Depending on the selected type, the setting items in the [Comm.
Parameter] dialog or those for the memory vary. Select [1 : 1] for 1 : 1 connection.
- [Local No.]
Set the port number of the PLC.
- [Trans. Mode] (Trans. Mode 1/Trans. Mode 4)
When the PLC has a transmission mode setting, set the same on the V7 series.
(This setting must be used for PLCs of MITSUBISHI, OMRON, HITACHI,
YOKOGAWA, Toyoda Machinery and YASKAWA.)
- [Baud Rate] [Signal Level] [Data Length] [Stop Bit] [Parity]
Make the same setting as the PLC. (Refer to “Chapter 5 Connection to PLCs.”)
[Baud Rate] (4800, 9600, 19200, 38400, 57600, 76800, 115 kbps)
Set the same communication speed as the PLC.
[Signal Level] (RS232C/RS422)
Set the same communication interface as the PLC.
[Data Length] (7-bit/8-bit)
Choose either data length for communication.
[Stop Bit] (1-bit/2-bit)
Choose either stop bit for communication.
[Parity] (None/Odd/Even)
Choose any of the parity options for communication.
- [Send Delay Time] (0 to 255) (Unit:
×
1 msec)
Set a time delay in sending the next command to
the PLC after receipt of a response from the PLC.
Normally use the default setting.
- [Start Time]
Set a time delay in seconds in starting communications on the V7 series to avoid a
delay in PLC processing that may occur when the V7 series and the PLC are turned
on at the same time.
