16.1 PLC Connection 16-11
NW0LA-RS2, NW0LA-RS4 (parameter setting)
On the PLC loader, set parameters for general communications.
Be sure to match the settings to those made under [Communication Setting] of the editor.
Available Device Memory
The available setting range of device memory varies depending on the PLC model. Be sure to set within the range available for
the PLC to be used. Use [TYPE] when assigning indirect device memory for macro programs.
*1 For the input/output memory, the variable name cooperation function of the PLC1 must be used. Indirect designation is not available
with the input/output memory.
*2 Double-word addresses (%MD1., %MD3., %MD10.) can be specified only for PLC1.
In the case with PLC2 to PLC8, access to the above addresses is possible when the data length is set to 2 words in the word address
(%MW1., %MW3., %MW10.).
Example: When accessing the address in %MD1.100:
Set the data length to 2 words for %MW1.100.
*3 The assigned device memory is expressed as shown below when editing the screen.
- For %IX or %QX:
- For %MX1., %MX3., or %MX10:
Item Setting Remarks

Baud rate 4800 / 9600 / 19200 / 38400
Parity Odd / Even / None
Data bits 8
Stop bits 1 / 2
Variable name cooperation function
The variable name cooperation function can be used only for PLC1. For device memory assignment, basically use the
variable name cooperation function. It is recommended that you specify a device memory address in the [AT] field
to define the area (variable) that is used for communications with the V9.
