RE: Bitwise alarms in CCW for PanelView 800

Posted By Andrew Roy May 01, 2023 04:47:00 PM
Found In Egroup: Automation Control \ view thread
Update... I found a work-around of sorts. I defined Boolen tags for the alarm triggers in the HMI project, which reference the appropriate bit of the integer tag in the PLC. At least the SCADA system can still reference the entire integer tag as originally intended and I didn't have to change the PLC ...

Bitwise alarms in CCW for PanelView 800

Found In Egroup: Automation Control \ view thread
Hello, I need to setup bitwise alarms in CCW for a PanelView 800, but I don't want to define a bunch of boolean tags. In FactoryTalk View, we could define alarms to trigger from a specified bit of an integer tag. But that column in CCW only allows values of 0 or 1 when the alarm is not numeric. So then ...

Well Shawn, You were right. The IP address does load from the SD Card for the 5370. I retested yesterday. This time I took into consideration that the IP address for the 5370 should load from the SD Card as well. So I was careful not to create a scenario where loading the SD Card on another machine ...

Philip, There was no entry in the XML file for LoadCommConfiguration. When I have time, I will add this entry to the XML file and try it again. NO Why would it behave one way with the original SD Card and another way after copying the files to a different SD Card? The SD card was empty ...

I did not expect the IP address in the 5370 to change at all. If you open the project in Logix Designer offline from the controller, the IP address is not shown. Which would indicate that the IP address is not part of the project, as we all know. I had asked tech support if I could send just the files ...

Hi Philip, I'm using the Compact GuardLogix 5370 Safety Controller (1769-L30ERMS Revision 33.012). The Ethernet port is integral to the controller, not a separate module. ------------------------------ Andrew Roy ------------------------------

Thank you Philip, I tested that scenario on a couple machines here. When I used the exact same SD card to load the project on another machine, everything worked perfectly. But when I copied the files from one SD card to the other, the process had a glitch. The project did load from the SD card and ...

Hi Shawn, Do I really need to send my one and only SD card? Or can I send the files from my SD card via email? Sending my SD card accross the ocean to another country would waste valuable time. And I may never get it back. Thanks, Andy ------------------------------ Andrew Roy ...

Hello, The CompactLogix PLC has a memory card slot. If it were a Siemens PLC, I could send a program update to be implemented via the memory card and nobody onsite with the machine would need to have the program source code or any specialized software. I'm not finding any way to do that with the ...

When I ran into that issue, it was because our license info was not in the system correctly. After you enter your serial number, PCDC will only show you versions for which you have a valid license. I called the tech center and they corrected the issue for me while I was on the phone with them. ...

Hello, I moved some code into a UDFB and it's not working the same as it did when it was in the general program. The local variables appear to be stuck at zero, as if they get reset every pass. Is it possible the local variables in a UDFB are really temporary variables? I can't find any documentation ...

Hi Chris, When the HMI is FactoryTalk View ME, we don't need to create explicit MSG instructions in the PLC program for the HMI. Does this same concept still apply? Would the FactoryTalk HMI communications really be more efficient if the HMI data were consolidated into one or two data tables? Since ...

I like the idea of an ST block within a ladder program. An ST block could allow you to implement For-Loops, While-Loops, If-Else and Case statements into a Ladder program. I imagine the size of the ST block would have to be limited. Happy New Year ;-) ------------------------------ Andrew Roy ...

Eileen, If the account managers had any real power to affect change, I believe much of this wish list would have been addressed years ago. I am not hurling accusations here, Eileen.

Hi Jeremy, Unless it has a negative impact on their bottom line, Rockwell has no incentive to implement such improvements. Maybe I'm just cynical, but I get the distinct impression that Rockwell doesn't listen to complaints with any bent towards internal improvement. I bet nobody at Rockwell will ...
