Ladder Refresh Type Analog I/O Modules
When using a ladder refresh type analog input or output module, the first data register number can be designated in the
ASNT macro dialog box. The quantity of required data registers depends on the model of the ladder refresh type analog
input or output module.
Data register numbers and parameters are shown in the table below.
Ladder Refresh Type Analog Input Module Data Register Allocation (FC4A-J4CN1, FC4A-J8C1, and FC4A-J8AT1)
* Data registers for channels 4 through 7 are reser ved on the FC4A-J4CN1.
