TagID – provide an additional field in which an associated name (third party cross reference or other string) can be stored. It can also be an additional name used to identify this PackML System.

PackMLVersion – provides the version of the supported OMAC PackML

Admin provides administrative functionality required for the PackML OPC UA server. It is defined in section 6.3.4. The administrative functionality exposed by this Object should be restricted to only users with administrative rights.

Status provides the status information required for a PackML OPC UA Server. It is defined in section 6.3.3.

SetUnitMode method allows an OPC UA Client to change the mode of the machine. The available modes are part of the supported Modes and a Client can pass any of the values listed. The Method may return an error if the requested mode is not allowed based on either the current mode of the machine or the state of the machine. For additional details see the definition of the SetUnitMode Method in 6.7.2

SetMachSpeed Method allows a Client to change the machine speed.

SetProduct Method allows a Client to change the product(s) and the ProcessVariables and Ingredients. For additional details see the definition of SetProduct Method in 6.7.4 .

SetParameter Method allows a Client to set the parameters for the machine. For additional details see the definition of SetParameter Method in 6.7.17.

RemoteCommand Method allows a Client to send a command to the UA Server that is to be passed to the PackML Server and or upstream or downstream Servers. Parameters sent to the Remote system are typically used in the EXECUTE and STARTING states for a production task. With the restriction that RemoteCommand Parameter Values are limited to REAL values. For additional details see the definition of the RemoteCommand Method in 6.7.15

SetInterlock method allows a Client to set one of the interlocks associated with the system. For additional details see the definition of the SetInterlock Method in 6.7.16
