PLC2Way
•
The “PLC2Way” function is an original network function where one V7 series can be connected to
two PLCs. Even if the manufacturers of these PLCs are not the same, they can be connected to
one V7 series.
•
Connect one PLC to the CN1 connector, and the second PLC to the MJ port.
•
With the PLC2Way function, it is possible to communicate with PLCs without special program in
the same way as 1 : 1 connection.
Two PLCs that are connected to the V7 series are controlled at the same time, and memory
read/write operations are available with these two PLCs.
•
Connection at the MJ port can be performed via RS-232C or RS-485 (2-wire).
With RS-232C, one PLC can be connected; with RS-485, a maximum of 31 PLCs can be
connected.
•
Constant reading/sampling of PLC data connected to the MJ port
When read/write memory addresses are preset on the temperature control network/PLC2Way
table, background data reading is performed at regular intervals. It is also possible to save the
read data in the V7 internal buffer, SRAM or CF card.
•
Data transfer between PLCs
The PLC memory data can be transferred to another PLC in blocks using a macro command.
•
For more information, refer to the PLC Connection Manual.
