When the data code in the target memory address is BCD:
The code (numerical data format) for the PLC2 memory is fixed as mentioned
above. (Refer to page 3-37.) Normally the V7 series handles numerical data as
“DEC with signs.” For numerical data to be handled on the PLC connected to
the MJ port, select [Word] or [Double Word] for [Data Type]; for data to be
handled as bits, select [Bit].
Example: [Word] [Double Word]
Example: [Bit]
When (3) is double-clicked, the [Temp. CTRL/PLC2Way Table Setting] dialog is
displayed.
Set the memory addresses of the target PLC memory and target internal memory at
one time in the [Temp. CTRL/PLC2Way Table Setting] dialog.
[Use Periodical Reading]
Check this option when the following operation is required.
• Constant read from the PLC memory
• Data sampling in the PLC2 memory
[Read Cycle] (sec)
Set the cycle of reading data in the PLC2 memory.
[Store Target PLC Memory]
When storing data read from the PLC2 memory into the PLC memory, check this
box and set the desired memory address.
[Store Target Internal Memory]
When storing data read from the PLC2 memory into the V7 internal memory,
check this box and set the desired memory address.
[Temp. CTRL/PLC2Way Comm. Setting]
Clicking this button brings up the [Temp. CTRL/PLC2Way Comm. Setting] dialog
and allows you to review the setting.
