4 Analog I/O Specifications

4.3.1 Analog Input Modules

4-36

(3) The five input registers that are allocated are used as shown in the following

table. Here, n is between 0 and 507.

c) I/O Data Format

The following items can be set to define the I/O data format. There is, however, gen-
erally no need to change these settings, except for the mode setting, because the
default settings can be used for most normal applications.

(1) Mode Setting

(a) Analog Input Module (

±10V, 4 CH)

The data format can be set to either of the following formats.

±2000 mode: ±10 V / -2000 to +2000

• 0 to 4000 mode:

±10 V / 0 to 4000

The MEMOSOFT is set by default to the ±2000 mode.

(b) Analog Input Module (0-10V, 4 CH)

Only the 0 to 4000 mode can be used as the data format.

• 0 to 4000 mode: 0 to 10 V / 0 to +4000

The MEMOSOFT is set by default to the 0 to 4000 mode.

(c) Analog Input Module (4 to 20 mA, 4 CH)

Only the 0 to 4000 mode can be used as the data format.

• 0 to 4000 mode: 4 to 20 mA / 0 to +4000

The MEMOSOFT is set by default to the 0 to 4000 mode.

(2) Software Filter Setting

Software filters can be set. The following three settings are available.

• No filter: The input signal read by the Module is input by the CPU Module

at each scan.

• 3 input average: The average of three input signals read by the Module is

input by the CPU Module at each scan.

• 5 input average: The average of five input signals read by the Module is

input by the CPU Module at each scan.

The MEMOSOFT is set by default to use no filter.

Note: (1) The sampling interval for signals read by Input Modules is 4 ms.

(2) The data read by the CPU Module each scan is the most recent

signal or average read by the Input Module.
