4-2 Analog Output Module
(1) Module status register (offset address +0)
Operation information and RAS information of this module are stored in this register.
* When using D300win, assign a WORD type variable to this register. If you access by the bit, assign a BOOL type variable to
each bit.

Error Cause and remedy
EEPROM calibration
data error
If the cali bration data of EEPROM i s destroyed or if EEPROM cannot be wri tten, this error is notified.
Module internal EEPROM i s abnormal.
EEPROM user setting
data error
If the user setting data of EEPROM is destroyed, this error is noti fied.
If thi s error occurred, all parameters need to be reset. If thi s error recurs even after parameters are
reset, the module seems to have failed.
Internal power supply
down
If the internal power supply of the module becomes down, this error is notified. B ecause output is
stopped in case of thi s error, interlock should be provi ded as needed for the interface with external
devices.
Switch setting error If the operation setting switch on the module rear panel i s set at i nvalid position, this error is notified.
(2) Switch setting No. (offset address +1)
The set value (INT type) of the operation setting switch that is provided on the module rear panel is stored in this memory area.
* When using D300win, assign an INT type variable to this register.
(3) Digital input values of channels 1 to 8 (offset address +4 to +11)
The digital values to undergo D/A conversion are stored in these memory areas. Just after the system is powered up, 0 V or 0
mA is output. When the initialization of the module is completed, the analog value that corresponds to the digital input value of
0 (zero) is output, and initialization completion flag (bit 15 of offset address +0) is set ON. For more information of conversion
characteristics, refer to “2-3 Conversion Characteristics”.
* When using D300win, assign INT type variables to these registers.
