V-Link
• “V-Link” is the network where the computer reads from and writes to the internal memory of the V7
series, memory card, PLC memory or temperature control/PLC2 memory using a dedicated
protocol.
• Connection with computer
When connecting to the V7 series or a V706 equipped with DU-01, use the MJ1 port. For
connection to the PLC using a temperature controller or the PLC2Way function, use the other MJ
port and use CN1 for communications with the PLC. Data of the PLC or temperature controller
can be collected through communications with the V7 series. Data collection is available even
between the products of different manufacturers.
When connecting to the V7 series or a V706 equipped with DU-01, use the MJ port.
• Either signal level RS-232C or RS-485 can be selected.
With RS-232C, one V7 series can be connected; with RS-485, a maximum of 31 V7 series can be
connected.
