XGB Analog edition manual
7) Maintaining valid conversion value
(1) In case that retaining valid conversion value is set at the same time, if the invalid value is
come, the late valid value will only be retained. For example, firstly, it is operated with 4
~20mA. Secondly, 10mA comes in. Finally, the signal is immediately falling down to 3mA
without falling down the current continually. In this case, relevant channels will retain the
output value of 10mA.
(2) When this function is set, digital output value related with actual range of analog input is
only shown. Refer to the actual range of the analog from "chapter 13.4".
(3) This function can only be operated within input range.
1) 4 ~ 20㎃
2) 0 ~ 20㎃
Refer to the using method from "chapter 13.6.5" for detail..
(4) Setting of retaining valid conversion value is as below.

(3) When errors of two or more are caused, the high priority error code is saved. And when
the same error code is caused in channels of two or more, the error code of low channel
number is saved preferentially.
9) System area (after No. 23)
(1) The system area (after No. 23) is prohibited for reading/writing.
Caution
If this area is changed, the product can malfunction and be broken.
