Read Address and Write Address
Section 5-6
Percent data is set by registering a setting in a Numeral Display and Input
objects with the integer set to four digits and the decimal to two digits. The
conversion rate/offset for the unit and scale setting is set to a multiplier of
0.01.

Read Address and Write Address
Even if the tag ITEM is the same for the read address that is read and dis-
played from the PLC to the NS-series PT and the write address that is written
to the PLC from the NS-series PT, the addresses are different.
For example, the following table shows the addresses when Basic PID is
used.
Note
If any values in the receive area (i.e., I/O memory in the CPU Unit) have not
changed, Receive All Blocks in the Loop Control Unit will not receive any data
from the CPU Unit. Therefore, after changing the mode from MAN to AUTO
and then back to MAN mode, such as for Basic PID, and 2-position ON/OFF,
and after changes to the MV set values, the MV value change operation will
not function unless there is a change between the current MAN and previous
MAN mode in the MV write value (receive area value) from the NS-series PT.
In this case, perform an operation to change the MV write value (receive area
value) from the NS-series PT once, and then perform processing.
The following precaution is required for the Loop Control Unit.
When using an NS project file built with the Face Plate Auto-Builder for NS,
the NS-series PT communicates with the Loop Control Unit via the memory of
the CPU Unit, using the Send/Receive All Blocks block in the Loop Control
Unit. Therefore, compared with accessing the Loop Control Unit using the CX-
Process Tool or CX-Process Monitor software, the communications response
is slower.
