Symbolic #85

Closed drexxi closed 4 years ago

drexxi commented 4 years ago

Hello,

is it possible to ask for a value with the symbolic adress?

Lichtjaeger commented 4 years ago

NodeS7 uses the classic S7 protocol. This leads to the following disadvantages:

not secure (must be switched on manually (PUT/GET enabling))
only non-optimized blocks are accessible
absolute memory addressing only

I want to start the read function from javascript in my browser. I need to implement the code in a svg file, in the svg file im able to run javascript.

Hey drexxi,

as answered in this issue #50 it is not possible to run this library in browser. I would also suggest to build your code on NodeJS and publish the data to browser via websockets.
