ALARMS SCREEN IN GTWORKS/MITSUBISHI

[netdomain]

Hi, Does anyone has a HMI example of Alarm screens created in GT Works? I am reading the manual, but still unsuccessful in creating a working alarm. Here's what I am trying to do. I have done it on the base screen, but I dont want to put alarms on base screen. Lets say I am on MAIN SCREEN, and if bits M0 , M1, and M2 are set from OFF to ON, then alarm screen should pop up saying 1. Estop Error 2. Fense Error 3. Light Curtain Error. Can anyone create a dummy example for popup alarm screen please? Any help would be greately appreciated. Thanks

Well for one, the model of GOT would be very helpful. I have examples of alarms in the A900GOT and the GOT1000. www.meau.com has examples of alarm screens for the GOT1000 in the Downloads section under Programming Examples.

Hi Crossbow, I have GOT1000. I have downloaded the alarm screen from meanu site but those are not popup alarm screens... I want one where it pops up on the main screen when alarm occurs. Do you have such example of alarm please?

[Crossbow]

You need to be looking at the Advanced Alarms. Specifically, the advanced alarm observation objects and the advanced alarm popup. They're very easy to work with, and are covered in detail in the Screen Design Manual. What kind of problems are you having with the alarm example from www.meau.com? I know there is one that deals with advanced alarms.

Use your F bits in the program and they are directly linked to an alarm screen inside the GOT. Then inside the GT Designer you can call easch bit what you want.

How are annunciators directly linked? Can you please give me an example? I was using regular bits to latch alarms. Does F bits make it easy for alarms?

F bits are fault annunciator bits in the PLC. To the best of my knowledge, they have no interaction with the GOT, short of the fact that they are PLC addresses and can be used on a screen just like any other. As I said before, check the Advanced Alarms, look at the Advanced Alarm Popup Display, that will cause a text banner to scoll across the top, middle, or bottom (your choice on each screen) which shows the active alarms. Another simple way is using the registers that control screen number displayed. When an alarm happens in the PLC, simply move the number of the screen you want to display into that register, and the selected screen will be displayed.
