Notes:
•
The least significant digit of input, output, internal relay, and special internal relay operand number is an octal number (0
through 7). Upper digits are decimal numbers.
•
The allocation numbers of expansion inputs and outputs start with I30 and Q30, respectively.
•
Note that input and output allocation numbers are not continuous between the CPU module and expansion I/O modules.
•
A maximum of 7 expansion I/O modules can be mounted on all slim type CPU modules. The maximum I/O points depend
on the CPU module type as described below.
•
The 20-I/O type CPU module (FC4A-D20K3 and FC4A-D20S3) can add a maximum of 128 I/O points, and use a maximum
of 148 points of inputs and outputs in total.
•
The 20-I/O relay output type CPU module (FC4A-D20RK1 and FC4A-D20RS1) can add a maximum of 224 I/O points, and
use a maximum of 244 points of inputs and outputs in total.
•
The 40-I/O type CPU module (FC4A-D40K3 and FC4A-D40S3) can add a maximum of 224 I/O points, and use a maximum
of 264 points of inputs and outputs in total.
•
Four models of the slim type CPU modules (FC4A-D20RK1, FC4A-D20RS1, FC4A-D40K3, and FC4A-D40S3) with system
program ver. 201 and higher can use the AS-Interface master module, and have additional internal relays and data regis-
ters for AS-Interface communication. Use WindLDR ver. 4.20 or higher to program the AS-Interface operands. For details
about AS-Interface communication, see a separate user's manual for the AS-Interface master module.
•
When the AS-Interface master module is not connected, these AS-Interface operands can be used for basic and advanced
instructions like ordinary internal relays and data registers. Note that these operands cannot be designated for keep or
clear operands in the Function Area Settings dialog box in
maintenance communication protocol and the designated reset input do not work on these AS-Interface operands. The sta-
tuses of these AS-Interface operands are maintained at power-up or when a reset input is turned on, but are cleared when
a keep data error occurs.
