Object and Modbus Mapping Delete via Script

[BrentW]

Hi all,

I need some help with database manipulation. I'm familiar with the correct methodology for adding objects via script.
What I am interested to know is the best practice for deleting objects via script.
Specifically, I need to delete an object and also remove the affiliated link in the modbus mapping.

EDIT: Also how to delete modbus devices via script.
I note the method does not work;

require('json')
function json.data()
return { id = 1 }
end
dofile('/lib/genohm-scada/web/modbus_devices/delete.lua')

Thanks in Advance,
BW
