When the breaker trips i want the motor to show red and blink.When i close my coil ,i want motor to show green ..When breaker trips again i want motor to show red with blinking..How do i do it in hmi not the blocks.
Hi Dennis
If I understand you correctly then the short answer is you can´t. You need to send some status signal from the PLC to the HMI in order to know if the motor is running or is in alarm state. For this you have two options, either send out two bools from the PLC to indicate drift and alarm or have a status int (or word or whatever you want).
When using the boolian solution you will have the motor symbol in layers, the bottom layer is when the motor is off and then you can add in the appearance that it should turn red and blink when the alarm bit is active, the top layer is visable when the motor is running and again you add in the appearance that it should turn red and blink when the alarm bit is active.
When using the Int solution you only have one symbol but in the appearance you need to do a little bit more work. Where motor inactive = 0 (colour gray or whatever , you didnt specifie), Motor active = 1 Green, Motor Inactive Alarm = 2 Gray and blinking red, Motor active and alarm = 4 green and blinking red.
Hope it helps somewhat.
