Error Handling 8.3.2 Low Voltage (Power Supply, Error #2) Supply voltage: 24 VDC -20%/+20% The integrated voltage monitor has a two-stage reaction to voltages dropping below set limits: 1st stage Cause supply voltage drops to approx. < 17.5 V Reaction � ERROR_IRQ_module is run (see page 82) � The program keeps running for the time being Variables may be reset unintentionally if the user program continues to run at this stage. This would be caused by remote inputs already detecting a 0 signal due to the low voltage. Indication � "failure" LED flashes (2x) � Bit 1 in "SYSTEMINFO.ERROR" is set 2nd stage First alternative Cause The voltage goes back up to 24 VDC ± 20% Reaction � "failure" LED stops flashing � Bit 1 in "SYSTEMINFO.ERROR" is reset � The program keeps running without interruption Second alternative Cause The supply voltage keeps dropping further to < 7 V Reaction The 5 V system voltage is interrupted 182 E 700 GB
=> - STOP: The program is stopped Error Handling - RESET: all outputs and non-RETAIN variables are reset - All LEDs extinguish Corrective action � Preliminary user program action to protect the buffered operands: Running the user program should be suspended until the cause is at its second stage or until a practically feasible time has elapsed. Error IRQ module, example: VAR Wait: TP; (*max. LOW time*) LOW_ongoing: BOOL; (*max. LOW time exceeded*) ON: BOOL; Active: END_VAR BOOL; PROGRAM low voltage On:=TRUE; WHILE On OR Active = TRUE DO Wait (IN:=On, PT:=T#1000ms, Q=>Active, ET=> ); On := FALSE; END_WHILE IF SYSTEMINFO.Error.1 =TRUE THEN LOW_ongoing :=TRUE; ELSE LOW_ongoing :=FALSE; END_IF 183
