Control Registers
Data registers are set as the devices to store the parameters for the analog I/O module.
Multiple words are used starting from the set data register. The number of words of data registers that are used differs according
to the analog I/O module model and the "Use data register for setting parameters" setting.
"Use Data Register

FC6A-J2C1
Parameters"
FC6A-J2C4
Disabled
Enabled
When "Use data register for setting parameters" is disabled
Only the data and status are stored in control registers.
Note: At the first scan when stop changes to run, the analog I/O module is set with the parameters (initial values) configured in WindLDR. While
the parameters are being set, the analog I/O module status is initializing. After the parameters are finished being set, the analog I/O module
operates normally.
When "Use data register for setting parameters" is enabled
In addition to the data and status, the operation mode, data type, minimum value, and maximum value are stored in control
registers. For analog inputs, the filter value and thermistor settings are also stored.
Notes:
When the CPU module is switched from stop to run, the analog I/O module is set with the values of the operation setting data registers.

The parameters (initial values) configured in WindLDR are transferred to the operation setting data registers when the user program is

updated or when a keep data sum check error occurs.
When the "Write operation setting parameters" input changes from off to on, the analog I/O module is set with the content of the operation

setting data registers in the END processing of the same scan.
While the parameters are being set, the analog I/O module status is initializing. After the parameters are finished being set, the analog I/O
