Hey guys, So I'm using CX-Designer 3.52 and I'm having trouble finding out whether or not an acknowledge bit can be used for an Alarm/Event Summary History window. I'm doing a project with some temperature probes and when a set value is reached, an alarm occurs. There are 8 probes, so an operator should be able to acknowledge individual alarms that the PLC and SCADA software can see (so must be bit/word addressable between PLC, SCADA,HMI). I was hoping there was some setting in the internal memory that could set a bit in the PLC, SCADA when an alarm is acknowledged as well as move the alarm in the HMI to the alarm history page. Has anyone had any experience with this in CS-Designer?? Regards Cameron

I believe I have sorted it. I changed some more settings, being : advanced settings in the system settings, and then setting the switch screen at high speed, and this seemed to get the screen pop ups working instantly. The only problem/concern now is the comm's error that are supposed to be showing up from different PLC's that are not online.

Hey guys, I'm using CX- Designer v3.520 and CX- Programmer v9.43 for a project. We are using 4x CJ2 PLC's, 4x CPIL PLC's, and 3x NS8 HMI screens. All are communicating using EtherNet/IP on the same subnet. The Comms setting in the CX-Designer are Comm timeout - 10sec, Retry counts - 5, Comm auto return - ON, Intervalas of message-Comm - 200ms. The problem we are having is that the comms work fine, however it takes 20-30 secs for the HMI to respond onsite. Pinging the HMI's from the main PC where the router is located show us a that the communication between the PLC's are fine (i.e less than 5-10ms). Not all PLC's are currently online, or powered up. Some of the settings that have been changed that are concerning are the comm auto return, where originally it was off, and as expected those PLC's that weren't online, would give timeout warnings of no communication. Since changing the comm auto return to 'on', the comm timeout messages have disappeared, where some PLC's are still offline (so should be showing a timeout, or comm's error right?). If anyone has any experience with multiple NS screens, and PLC's with similar problems and how they fixed them, their input would be greatly appreciated. I can take screen shots of more settings, if necessary, other than that a call to OMRON and reading through the CX-Designer manuals are looking like the only solution. looking forward to sorting this out. Thanks Cam
