How to scroll faults in ML1400 and PV800?

Hello Friends

I have a ML1400 program with 10 message faults aprox. and a PV800 program  with a Multistate Indicator showing the faults.

When exists only 1 fault, the HMi is showing correctly 1 fault, the problem is when I have 2 o more faults, in the PLC program, 2 o 3 faults are activated, but in HMI just the last fault is showed.

How can I scroll the faults to show the 2 or 3 faults activated?

Thanks in advance.
