You can find the description for any status code ( or at least the ones with more than 3 digits ) by opening control builder's online help and searching for the status code ( in your case "-7006" )
( also, Typically I would recommend you use "Valid and NOT Error" to enable the Pulse generator for the Modbus read. )
