App1-12 Appendix 1 PLC2Way
When (2) is clicked, a data type for the PLC2 memory can be set.
[Word]
This is the data length setting for the memory address to be used. Numerical data of one
word is handled.
Data is transferred to the target memory address in the numerical data code of the PLC2
memory.
[Double Word]
This is the data length setting for the memory address to be used. Numerical data of two
words is handled.
Data is transferred to the target memory address in the numerical data code of the PLC2
memory.
[Bit]
Data in the PLC2 memory is handled as bit information of one word.
Data is transferred to the target memory address without conversion.
[Dummy Word] [Dummy Double]
The memory addresses for [Target PLC Memory] and [Target Internal Memory] are
automatically allocated consecutively in the [Temp. CTRL/PLC2Way Table Setting] dialog.
If you would like to skip any memory address, keep the cell in the [Temp. CTRL/PLC2
Mem.] column blank (no setting). It is regarded as a dummy word or double-word. In this
case, “0” is stored in the target memory address.
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 App1-9.) 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].
