4-2 Analog Output Module
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 or read out, this error
is notified. Module internal EEPROM is abnormal. If this error occurred, it is necessary to replace the
module.
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.
(1) Module status (offset address +0)
Operation information and RAS information of this module are stored in this register. This register is common to D/A conversion
mode and parameter mode.
* 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.
(2) Operation setting switch setting No. (offset address +1)
The set value (INT type) of the operation setting switch on the module rear panel is stored in this memory area.
* When using D300win, assign an INT type variable to this register.
