OPERATION CHECK AFTER INSTALLATION
3-7
3.2.1 PA software errors
Each unit communicates using a single master/multi-slave protocol, such as Modbus. When polling
with the PA as master (semaphore), the other units respond in order (same as JHS-770S). If the
software does not function correctly due to a PA ROM (FROM) malfunction, all functions, including
upgrades, stop functioning. In this case, it is possible to reboot the PA and only PA upgrades can be
done from the following screen.
[Upgrade screen directly after a PA software error has occurred]
The screen above appears when upgrading by connecting a notebook PC to connector J105 (Dsub9)
on the CAH-2415 PA UNIT board. Connecting a notebook PC to a controller displays the following
upgrade screen.
