•
A general purpose computer or an ASCII unit of the PLC (master station) controls the V7 series
(slave station) using dedicated commands.
•
The V7 series internal user memory addresses ($u) must be used for memory allocation for
switch, lamp or data display parts.
When the master station specifies a screen number, data is written to the internal memory address
($u) allocated for the screen. If the screen is switched internally, the new screen number is read
and is written to the internal memory address ($u) allocated for the screen.
•
For 1 : 1 connection, the V7 series can send an interrupt to the master station through switch
activation, write command from the keypad, and screen change.
•
Use CN1 of the V7 series for connection with a general-purpose computer. Either signal level
RS-232C or RS-422 (RS-485) can be selected.
•
In addition to 1 : 1 connection, 1 : n connection is available between the general-purpose
computer and the V7 series via RS-422.
(A maximum of 32 V7 series can be connected.)
For 1 : n connection, interrupts cannot be used.
•
For more information, refer to the PLC Connection Manual.
