3.4.14 Disconnection detection flag (buffer memory address 49: Un\G49)

3.4.15 Increase/Decrease digital limit value (buffer memory address 70 to 73: Un\G70 to
Un\G73)

(1) If the disconnection occurs in the output range of either 4 to 20mA, 4 to 20mA
(Extended mode), or when the user range setting 1 is set to the channel, the bit
corresponding to each channel turns to "1". (Refer to Section 3.2.6.)
(2) If disconnection is detected on any one channel, Disconnection detection signal
(XD) also turns on.
(3) Turning on Operating condition setting request (Y9) or Disconnection detection
clear request (YD) clears the disconnection detection flag.

(1) For rate control, set the range where the digital value can be incremented and
decremented in a single conversion cycle (10ms). (Refer to Section 3.2.5.)
(2) The setting range is 0 to 32000.
If any value outside the setting range is set, an error (Error code: 80 ) occurs.
(3) To validate values set to Increase/Decrease digital limit value, turn on and off
Operating condition setting request (Y9). (Refer to Section 3.3.2.)
(1) Set the upper and lower limit values of the digital input value for providing the
warning output. (Refer to Section 3.2.4.)
(2) The setting range is -16384 to 16383.
Make setting so that the upper limit value is greater than the lower limit value.
If any value outside the setting range is set, an error (Error code: 61 ) occurs.
(3) To validate values set to Warning output upper/lower limit value, turn on and off
Operating condition setting request (Y9). (Refer to Section 3.3.2.)
