Setting procedure
1.
When adding a new module, select the module whose module model name has "(FX2N)" at the end.
[Navigation window]

[Module Information]
Right-click
[Add New Module]
2.
Configure the same parameter setting as the one of when the Normal mode is used.
3.
After writing the module parameter, turn off
→
on or reset the CPU module.
• Switching between normal mode and FX2N allocation mode is not possible during operation.
• Do not switch to the FX2N allocation mode when the user range setting was adjusted by the resistance
temperature detector range in normal mode. If ‘CH1 input type/range setting (offset/gain setting)’(Un\G598)
is set to “user range setting” in the FX2N allocation mode when the setting is adjusted by the resistance
temperature detector range, an input type/range setting range error (190
H) occurs. To use the user range
setting in the FX2N allocation mode, set the input type other than “resistance temperature detector” to the
user range setting in the normal mode.

2CH Conversion Mode Function
A function that performs A/D conversion of 2CH in 1 ms and can update the digital output value at the same time. Only input
type "current", "voltage" are supported.
The combination of channels to update at the same time is as follows.
The sampling cycle per 2CH is 1 ms.
For each sampling cycle, the maximum and minimum values of the digital operation value are stored in 'CH1
Maximum value' (Un\G404) and 'CH1 Minimum value' (Un\G406).
