You need to enable : $ALM_IF.$ENABLE
Then use for last alarm : $ALM_IF.$LAST_ALM
for last user alarm: $ALM_IF.$LAST_UALM

Almost a year later, I'm bringing more questions about $ALM_IF
I guess there are a couple of ways to read the last alarm (explicit messaging or Karel).
Any idea how to read the other ones.
I've been reading about it in the last couple of days (without actually programming) and I can't find anything that can take me directly to $ALM_IF.$CURR_STAT for example
Any ideas ?
BTW, the reason that I'm is because we are buying lets say 4 robot for a system with only one pendant. 3 pendants are basically the price of one robot. That makes my life hell and I want to send the PLC-HMI all the info that I can
-
What PLC/HMI and comm package are you using?
-
I'm pulling the alarm out of a system right now.
Setup an explicit message with the following parameters, and it will be the current error.
If the message faults, its because there is no fault active.
The tag it is writing to is a normal string tag.
-
Doesn't look like there is a way to pull out a system var with Ethernet/IP explicit messaging.
However, you could write a Karel routine that pulls out the $ALM_IF structure, and dumps them into some string registers. Those can be read via explicit messaging.
EDIT: there is also Explicit Data Access, which allows reads of system vars, but it is also an option.
-
1) NO pull out system var
2) THis is the only Karel command that resembles what I want
GET_VAR Built-In Procedure
Purpose: Allows a KAREL program to retrieve the value of a specified variable
Syntax : GET_VAR(entry, prog_name, var_name, value, status)
Input/Output Parameters:
[in,out] entry :INTEGER
[in] prog_name :STRING
[in] var_name :STRING
[out] value :Any valid KAREL data type except PATH
[out] status :INTEGERand I have this
I'm going to try to read it
3) Fanuc mentioned the EDA but I don't have that option, even that I have EIP
Thanks Nation

I've not used explicit msg a lot. But I use KAREL to read sys vars and based on matches/conditions set a bit or send an error code over GO[*] and another one GO[*] for error type SRVO/MTN/etc. As an option...
-
I know it's silly, but you can try this one.
-
Other idea (If using Karel):
Just read 'ERRACT.LS' from memory.
It contains all the current errors...

Hey,Fabian:
about the sample,i have a question,I tried it on robotguide, but I couldn't get this parameter well. In addition, I can't find these three parameters in the variables: $ALM_IF.$CURR_PROG, $ALM_IF.$CURR_STAT, $ALM_IF.$CURR_LINE.
-
Hi,sir.Thanks for the reply. Your program is well written, and I can successfully load it. But I did not find in my robot parameters: 1, $ALM_IF.$CURR_PROG; 2, $ALM_IF.$CURR_STAT; 3. $ALM_IF.$CURR_LINE. It should be that the version of my robot and the application are inconsistent with the version you are using.

Hi,Fabian.
what options you install, to not use the pendant?
