X9
Operating
condition setting
completed flag
(1) This signal is used as an interlock condition to turn ON/OFF the Operating condition setting request
(Y9) when any of the following settings has been changed.
A/D conversion enable/disable setting (Un\G0)
CH Average time/Average number of times/Moving average/Time constant settings (Un\G1 to Un\G8)
Averaging process specification (Un\G24, Un\G25)
Input signal error detection extended/input signal error detection setting (Un\G47)
Warning output settings (Un\G48)
Scaling enable/disable setting(Un\G53)
CH scaling upper/lower limit value (Un\G62 to Un\G77)
CH conversion starting time setting (for 2-wire transmitter) *1 (Un\G78 to Un\G83)
CH process alarm upper/lower limit value (Un\G86 to Un\G117)
CH rate alarm warning detection period (Un\G118 to Un\G125)
CH rate alarm upper/lower limit value (Un\G126 to Un\G141)
CH input signal error detection setting value/CH input signal error detection lower limit setting
value (Un\G142 to Un\G149)
CH input signal error detection upper limit setting value (Un\G150 to Un\G157)
(2) When the operating condition setting completed flag (X9) is OFF, A/D conversion processing is not
performed. Under the following conditions, the operating condition setting completed flag (X9)
turns OFF.
When operating condition setting request (Y9) is ON
(3) Digital outputs are cleared immediately after this Operating condition setting request (Y9) turns ON.
Therefore, turn ON the A/D conversion completed flag before reading digital outputs.
