When the data code in the target memory address is BCD:
The code (numerical data format) f or the PLC2 memory is fixed as ment ioned
above. (Refer to page 3-37.) Normally the V7 series handles numerical d ata 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 targ et inte rnal me mory a t
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 th e PLC2 memory.
[Store Target PLC Memory]
When storing data read from the PLC2 memory into the PLC memo ry, check this
box and set the desired memory address.
[Store Target Internal Memory]
