For a facility that produces steel sheets for the automotive industry, an on-screen display is to be made with ibaQPanel showing the customer names of the last 5 coils produced in addition to the batch numbers. The “customer” text signal is created in a text shift register. The already existing "QP_Customer” text signal always contains the appropriate customer name for the production. This is manually entered into ibaQPanel but it can also be any other automatically-generated text. The trigger signal is fired each time a new coil enters the plant. Since the last 5 coils are supposed to be displayed, the register depth is set to 5.
Five digital text displays are configured in ibaQPanel, each of which accesses an indexed shift register text signals.
[1] = latest register, [5] = oldest register
The result: The customer names for the last 5 coils now appear in the right row. The most recent or current coil is at the top. The left row was implemented with digital numeric displays and analog signals in the (numeric) shift register module.
