Flowcode Support Board

Afternoon,

Is it possible to view available COM ports, and apply setting external to flow chart as well as Device nodes

i.e by using "dialogue box entry"

you can set the chart to look at COM5 and device with address = 1 - but this could Easley change

Steve

Part solved

Address Question Solved ...

Created a variable "Modbus_address" and used this in the slave ID field in the component macro

Evening

Is it possible to be able to select the comport from the panel ?
A user may plug into a different port especially if they have a USB Convertor etc.

Steve

Hi Steve,
Yes, looks like the default is to be able to select the com port by properties of the panel

Hello,

Any component properties you need the user to be able to set you can right click and Expose to top level. This adds the property to the top level panel properties which are visible to the user.

These exported properties can then be organised into folders and given more friendly names to help the user determine what each property does.

In your case I would expose the COM port property and also the Refresh property from the Modbus component.

Cheers Guy's will have a go later

Morning,

Having some problems if someone could please advise,

When i run the the green arrow is flashing on the dashboard, the red arrow doesn't flash
However i cannot see the Transmit LED flashing on my USB - RS485 Adaptor (shows as Com8 on my PC)

i have tested using winbus and i get a response from the meter.

Steve

Hello,

What USB to RS485 adapter are you using? I wonder if it requires flowcontrol to work correctly? Also check your other software doesn't still have the COM port open.

I use a dongle like this and it's working great.

Not getting much sense out of it at the moment
