Hi,
I have a Siemens S7-400 PLC connected to 10 operator panels (MP370) with over 1000 alarm messages. My client wants to synchronize the acknowledge status of the alarms between all the panels. If an alarm has been acknowledged on one panel, it should also be acknowledged on the other panels automatically.
Is there an easy way to solve this? My plan was to do an OR function of all the HMI acknowledge bits on the different panels and copy the result to the PLC acknowledge bits.
