App6-18 Appendix 6 Universal Serial Communications
- n + 7 (ENT2) entry information 2
The entry mode window number where a write operation was executed is written.
The relationship between the window number and base and the window number and overlap
is shown in the following table.
* In case of using the Table Data Display(s) as the entry targets of the Entry mode
The line number and the column number will be output to the address n + 1 and the block
number to the address n + 2 of the “Info. Output Memory,” when the bit No.12 of
“Command Memory” in the [Entry] dialog is ON [1].
In only this case, therefore, the window number cannot be referred because the block
number is output to the address n + 7 (ENT2) of the write area.
Please take note of this.
- n + 8 (GREPNS) global response
A response to a global command is written. The contents of a response are shown in the
following table.
-n+9 to n+15
Reserved for functions expanded in the future.
• Calendar
The values written in the calendar area are used for the calendar display. Set the top memory
number. The relationship between memory and the calendar is shown in the following table.
Calendar settings are performed in the read area under [RCVDAT (n + 0)] at the leading edge of
bit 11.
The V series calendar uses the CPU clock. When precise time is necessary, set the calendar once
a day. (Time loss: approximately 90 seconds a month.)
• Read Clear Top Address (Set user memory within internal memory.)
The read clear area is the starting area from which the V series clears words that were previously
read. Due to the fact that it is cleared to “0,” once this area is read, the data remains at “0” even if
you attempt to read again when a read response error occurs. Set the area’s top address number.
• Read Clear Words
Set the number of words that will be used for clearing the read area.
