Thanks Jared, you guys are awesome!

Great response time, much appreciated.

I put the newly created mango.properties file in the mango root folder, just with the specific lines as above.
This worked

Hi Terry,

Does the mango.properties file go in the overrides folder, or in the bin folder?
I can't even find it, so I will have to create it.

@terrypacker Thanks Terry

Hi,

I need to run a Windows command script for a process event, specifically to disable/enable a COM port.
Mango returns:

Process event handler is disabled, you must explicitly enabled it via mango.properties

I cannot find in the documentation what to put in the mango.properties file to enable this.
There is nothing obvious already in the file that is commented out?

Thanks for any help.

@mwright Further to this, "restarting of Mango fixes the issue", without doing anything with Windows. Suggesting that if Windows did grab the COM port for some process, it re-released it
after.

I'm not asking for anything, but future updates might include attempts to re-open the COM ports once this error is encountered, as this error just kills the data source.

@mwright Thanks for your response.

I will try updating the drivers, and/or the USB to 485 adapter, and ensure Windows UAC, or update isn't causing issues.

The weird thing is that it runs for weeks, then gets this error, and stops polling. It's almost
like Windows just grabs the port back for some test, like update or something.

Hi,

I'm hoping someone still monitors this forum!

I am running the latest version.
Windows 11, with a decent USB to 485 converter polling 5 sensors on COM3.

Getting error, and stopping polling:

java.io.IOException: jssc.SerialPortException: Port name - COM3; Method name - setEventsMask(); Exception type - Can't set mask.

Can anyone help? I can find anything on this.

So it's a standard Modbus response:

05 ACKNOWLEDGE

The slave has accepted the request
and is processing it, but a long duration
of time will be required to do so. This
response is returned to prevent a
timeout error from occurring in the
master. The master can next issue a
Poll Program Complete message to
determine if processing is completed

Hi,
I have a Modbus RTU Data source, and are getting the following error from most of the 5 Slaves on the BUS, but only from register 0:

Urgent 'Modbus RS485': Cool Room Temperature — Modbus RS485: Acknowledge

The slaves only have two registers being polled, 0 and 1.
Update period: 30 seconds
Timeout: 1000ms
Contiguous batches only

The event lasts only 0 millseconds

Has anyone seen this before?

Hayden
