Pack tags
Pack tags are used for communication with the higher-level controller or for direct communication between machines (machine-to-machine communication). A minimum of pack tags must be defined for compliance with PackML. Additional pack tags are permitted according to the description of PackML.
The status tags are programmed in the program according to the description. The command tags are set by the higher-level controller or other machines. The user assigns the command tags to the master machine module.
