SPECIFICATIONS 1 (a) If the detected digital output value rose to or above the process alarm upper upper limit value or fell to or below the process alarm lower lower limit value and entered the warning output range zone, the warning output flag (process alarm)(Un\G50) and warning output signal (X8) turn ON and the ALM LED is lit to indicate the warning. A warning will be output according to the following digital output values. Digital value causing warning output disable setting (Un\G53) scaling value (Un\G54 to Un\G61) 3 (b) After a warning was output, when the digital output value reaches a value less than the process alarm upper lower limit value, or a value more than the process alarm lower upper limit value, "0" is stored in the corresponding bit of the warning output flag (Un\G50) for the channel. The warning output signal (X8) turns OFF, and the ALM LED turns OFF when the digital output values in all channels get out of the warning output range.

When any other A/D conversion system (sampling processing, moving average, primary delay filter) is specified, this function is executed at intervals of the sampling time. (d) To use the scaling function, be sure to consider scale conversion before setting the CH 4 UTILITY PACKAGE (GX CONFIGURATORAD) 1: Enable CH SPECIFICATIONS digital output value (Un\G11 to Un\G18) SETUP AND PROCEDURES BEFORE OPERATION Item Value set in scaling enable/ 0: Disable CH 2 SYSTEM CONFIGURATION (1) Process alarm OVERVIEW Warning output function process alarm upper/lower limit value. 3.2 Function List 3.2.4 Warning output function 3 - 25 ONLINE MODULE CHANGE 3.2.4 8 TROUBLESHOOTING 3
