Master/Slave Applications
The master/slave network are typically used under the following circumstances:
•
Group Job Select: When two or more printheads are required to code onto the same side
packaging film
•
Group Control: When control for multiple LPAs is required from a single location.
•
Multiple Machine Mode: On high speed production lines where downtime needs to
be minimized for consumable changeover
Master/Slave Terminology
The master/slave network uses the following terminology:
•
Group Job Select: Allows connection of up to four standard LPAs (with LCD's), with Job
selection available only from the LPA configured as the Master. This mode greatly reduces
potential Operator errors when inputting variable data.
All other functions are performed at each local LPA's LCD panel.
•
Group Control: Allows connection of one standard (with LCD) acting as the Master, to up to
three Slave (without LCD) LPAs.
All Job selection, Setup, Diagnostics and Error reporting are
performed at the Master LPA only.
•
Auto Changeover: Allows the connection of two LPAs. Two LPAs are setup in auto
changeover mode, one operating as the master (1), the other as the slave (2). Job selection
available only from the LPA configured as the Master (1). All other functions are performed at
the local LPA's LCD panel.
LPA Terminology

•
Standard LPA: A LPA installed with CLARiTY Operator Interface
•
Slave LPA: A LPA without the CLARiTY Operator Interface
•
Master or Master LPA: A LPA that has been designated to act as the Master member of a
Master/Slave group
