In Labview 2009 how does one programatically access a password protected PLC if the password is known?

Hi Paul,

 

Can you give details like which PLC you are using and the version of LabVIEW etc... Also, are you using OPC servers to communicate with the PLC?

I have been trying out versions of  Kepware and Matrikon OPC servers for an AB Micrologix 1400 PLC with LV2009. Is there any provision to access password protected PLCs (for which the password is known) which is OPC server or PLC specific?
