■Arbitrary value
The value set in CH Conversion setting value for disconnection detection (address: 0110H to 0117H) is stored in CH
Digital output value (RWr2 to RWr5) and CH Digital output value (32 bits) (RWr10 to RWr17) when a disconnection is
detected.
The default value of CH Conversion setting value for disconnection detection (address: 0110H to 0117H) is 0. Although the
disconnection detection function is available with 0, the value can be changed to an arbitrary value.
When the value set in CH Conversion setting value for disconnection detection (address: 0110H to 0117H)
is 32767 or more, 32767 is stored in CH Digital output value (RWr2 to RWr5).
Moreover, the value set in CH Conversion setting value for disconnection detection (address: 0110H to
0117H) is -32768 or less, -32768 is stored in CH Digital output value (RWr2 to RWr5).
Detection cycle
This function is executed for every sampling processing.
When the disconnection is recovered
A normal digital output value is stored in the remote register in the next conversion after recovery from the disconnection.
Once averaging processing has been performed, the normal digital output value is stored in the remote register after the
disconnection is recovered and the averaging process cycle elapses.
Until the normal digital output value is stored in the remote register, the digital output value remains a specified value in the
conversion setting for disconnection detection (such as the down-scale value).
Moreover, the operation after the causes of the disconnection are eliminated and the connection with the external device is
recovered depends on the setting of Input signal error/disconnection detection automatic clear enable/disable setting
(address: 0109H).
■When the setting is Enable (0H)
When the disconnection is recovered and all Disconnection detection flags (RWrD) are turned off, the status changes as
follows.
• Disconnection detection signal (RX1B) turns off.
• The ALM LED turns off.
• Latest warning code (RWr1) is cleared.
