listBlocksOfType issue

[chewcw]

My PLC is a ET200S (IM151-8F PN/DP) CPU. I can successfully connect to the PLC, however when I perform ListBlocksOfType on DB type, I get an array of values:

result: [9,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,
0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]

The total count of the array is exactly how many DB I have, and 1st number 9 is also correct, but why all subsequent number are all 0's?

Just a simple code to demonstrate:

client.ListBlocksOfType(0x41, (error, result) => {
    if (error) {
        console.log(`error: ${error}`);
    } else {
        console.log(`result: ${result}`);
    }
});

Hey, looks like a bug. I'll have a look into it this weekend :)

I think I found the issue. If you got some time it would be nice if you can test this patch I'll then make a new release this weekend.

Sure I will give it a try and feedback later. Thanks for your quick action.

It works perfect now. Thank you so much.

Thanks for the feedback, how a pair of parentheses can help :) Just published node-snap7@1.0.2. If you face other issues feel free to report.
