Operating Instructions, 12/2019, C79000-G8976-C527-02
The positive acknowledgment of an RPC call does not guarantee or indicate successful
transmission and display of new display contents on the transponder. This can occur if the
transponder has been switched off during this time or is not within wireless range. Since the
commands to be transmitted in the wireless network do not reach the transponder or reach it
incompletely, no event message is generated in this case.
If an RPC call sets a field form to a value that is already set, an event message is sent
immediately. This happens during or very shortly after the RPC call. Event messages are
sent when a situation is reached.
If a field content still to be transmitted is overwritten again before the previous value could be
sent to the transponder, only the value set last is transmitted to the transponder. In this case,
only the writing of the last value is acknowledged by an event message.
The transmission of background images, fonts and theme files is given higher priority and
temporarily interrupts the transmission of text content.
