ANALOG I/O MODULE REPLACEMENT
Item
Scale-converts the digital input value to the set range of the D/A
conversion scaling upper limit value and D/A conversion scaling
Scaling function
lower limit value. This omits the programming of the scale
conversion.
Outputs an alarm when the digital value is out of the preset
Alarm output function
range.
Reads the wave data (digital input values) prepared in advance
Wave output function
and outputs analog data at the preset conversion cycle.
(3) Common functions
Item
Sets the resolution according to the application. The resolution
Resolution mode
mode setting is applicable to all channels.
Converts the analog values input through CH1 and CH2 to
Simple loop control (function digital values and calculates the converted values with the
expression) function expression. The calculation result is converted to the
analog value and output through CH3.
Turns on when the external power supply (24VDC) is supplied.
External power supply READY
When the external power supply READY flag (X7) is off, A/D
flag
and D/A conversion processing is not performed.
Stores the errors and alarms occurred in the L60AD2DA2 to the
Error log function buffer memory as a history. Up to 16 errors and alarms can be
stored.
Collects the errors and alarms occurred in the L60AD2DA2 and
Module error collection function
stores them in the CPU module.
Clears the error from the system monitor window of the
Error clear function
programming tool.
Saving and restoring offset/gain Saves and restores the offset/gain values in the user setting
values range.
Offset/gain setting function Corrects errors in the analog and digital output values.
*1 For the A1S63ADA, the resolution setting can be selected from 1/4000, 1/8000, and 1/12000 for both voltage and current
inputs.
The L60AD2DA2, however, does not support the resolution mode. To use the same digital value that is used for the
A1S63ADA, set the scaling upper and lower limit values that match the resolution of the A1S63ADA using the scaling
function.
Point
Replacement module L60AD2DA2 does not have the simple loop control (function expression) function.
When the simple loop control (function expression) function is used with A1S63ADA, the sequence
program needs to be addressed. (Refer to Section 4.1)

A1S63ADA L60AD2DA2 Precautions for replacement
The A1S63ADA is set the
status for all channels at once
using the HLD/CLR terminal
– on the front of the module.
With the L60AD2DA2, HOLD/
CLEAR can be set for each
channel.
