Robot Alarms and PLC

[cobenson]

Guys and Gals,
   Has anybody ever taken robot alarms and displayed them onto an Allen Bradley HMI? Besides using kepserver? I am wanting to try and eliminate kepserver. This would be one less thing to for the service techs to worry about.
  One other thing, we also control the robot speed from the HMI VIA kepserver as well.

Thanks in advance.

For the alarms, I know that you can do it with Ethernet/IP using explicit messaging. 0xA0 is the active alarm object. That's the easiest way I know of, if your HMI has EIP.

How much control do you want over the override speed? If you use Override Select, you can set up to four different override percentages with different combinations of two digital inputs. MENU -> SETUP -> Ovrd Select

If you need more control than that... you could manipulate the system variables for the override select itself, either with explicit messaging into a register or dumping a group input into a register, and setting the variable to that register in background logic.

$OVRDSLCT.$on_on_ovrd
$OVRDSLCT.$on_off_ovrd
$OVRDSLCT.$off_on_ovrd
$OVRDSLCT.$off_off_ovrd

Or you could do something with macros that are triggered by a digital input. There are a bunch of ways to do it.

Thanks for the info.
   We use nothing but PanelView Plus. So yes, it has Ethernet.

Kind of weird, we are using explicit messaging now, and it cuts the front part of the alarm off so all you get is the number and description. I.E. SRVO-009 all you get is the 009.

I haven't looked at it much, so I will when I get a chance.


Thanks again.
