How do I access ABCLX array elements in Plant SCADA's equipment editor (for example Scada_Float{12})? The braces cause an error when updating equipment: 'undefined variable reference'.
How do I access ABCLX array elements in Plant SCADA's equipment editor (for example Scada_Float{12})? The braces cause an error when updating equipment: 'undefined variable reference'.
try square brackets [ ].
Square brackets don't error (I can't connect to an actual PLC at the moment to confirm it works). I also found that double braces update to single braces (for example Scada_Float{{12}} becomes Scada_Float{12}).
I used "[]", but when I read the bool array in the PLC program, I found that one word of data was missing. That is, when I used the driver to read the 32nd element of the array, I actually read the data at the 64th element. At this time, Bool[32] in the program is "TRUE", but Bool[64] in the SMC is "TRUE" (Bool is actually a tag name). In my opinion, this is abnormal. Do you know what causes this phenomenon?The picture shows the data I tested with WWClient.
lu dream I believe your software is not Plant SCADA.
I am a little confused about the difference between these software, but this problem was solved by updating the OI Server (Operations Integration Supervisory Servers) driver version. Thank you for your reply.
