(c) Device number
The device numbers of this remote register are as follows:
Remote register name
Input signal error detection flag
(6) Alert output flag
Whether the upper limit value or the lower limit value causes the alert can be checked for each channel.
b15 b14 b13 b12 b11 b10 b9
0 0
The values of b8 to b15 are fixed to 0.
(a) The state of Alert output flag (RWrB)
• If the value is out of the range specified in CH1 Process alarm lower lower limit value (address: 010FH,
020FH) to CH4 Process alarm upper upper limit value (address: 011EH, 021EH), Alert output flag (RWrB,
RWr1B) corresponding to each channel turns to Alarm ON (1).
• Of the A/D conversion enabled channels and the alert output enabled channels, an alert detected even in
one channel results in Alert output signal (RX18, RX28) being turned on.
(b) Clearing Alert output flag
• When the digital operation value returns within the setting range, Alert output flag (RWrB) is automatically
cleared.
• Turning on and off Initial data setting request flag (RY9) results in this flag being cleared.
(c) Device number
The device numbers of this remote register are as follows:
Remote register name
Alert output flag
(7) CH Conversion value shift amount
Set the shifting amount to conversion value that is to be used for the shift function in signed 16-bit binary. The
digital operation values after shift-and-add are stored to CH Digital operation value (RWr2 to RWr5, RWr12 to
RWr15).
For details on the shift function, refer to the following:
• Shift Function ( Page 113, Section 8.12)
(a) Setting range
Setting range is -32768 to 32767.
(b) Enabling the setting
Once a value is set, the conversion value shift amount is valid regardless of turning on and off Initial data
setting request flag (RY9).
