Buzzer function with HV750

Post by zakirrajkot » Sun Oct 13, 2013 4:02 am

Dear All
Good Day To You All

I need a help for one my project in which i am using HV750 display for engine monitoring and alarm display.

I tried programming HV750 for Buzzer function. But couldnt succeed.
Here i am using state machine programming technique.In this i am continously checking status of "Dm1.IsActive" variable, whenever "Dm1.IsActive" value is 1 i want to turn ON "XM500.DOUT 2". The problem i am facing is there is no transition from initial to next state even if "Dm1.IsActive" value is 1.

I have attached program backup with this post.

Status of "Dm1.IsActive" and "XM500.DOUT2" is available on "Main Page" of main layer.

Please advice.

Regards
Zakir Sayed

Hello Zakir Sayed,

I'm looking at your configuration and the variable "J1939.XM500.DIGITAL OUT 2" is an incoming parameter so if you change the value of that variable your XM500 device will not see it and the value will be over-written when that parameter is received again from from the XM500 device.

If you want to have outgoing parameters they need to be added to the Transmit Device and the XM500 needs to be configured to receive it.

Another option is to use the HV750's digital output to control the buzzer.
