• A general purpose computer or an ASCII unit of the PLC (master station) controls the V606e
(slave station) using dedicated commands.
• The V606e 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 V606e can send an interrupt to the master station through switch
activation, write command from the keypad, and screen change.
• Use CN1 of the V606e 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 V606e via RS-422.
(A maximum of 32 V606e units can be connected.)
For 1 : n connection, interrupts cannot be used.
• For more information, refer to the PLC Connection Manual.
