Hello,
I am a PLC n000b and working on my first emulation project utilizing Automod as the emulation tool and a Siemens Simatic S7-400 PLC . I will have several questions going forward, but first, can anyone verify if this statement is true:
"The Fetch/Write protocol does not support the reading of datablocks with numbers greater than 255 - this is defined by the Siemens."
The I/O list that I am working with utilizes datablocks higher than 255, this may be an error in the I/O list creation, so I am looking to find out whether the above statement is true or false, which came from a counterpart.
Thanks,
~Chipley
P.S. - I'm also trying to figure out still how to ask the right questions about PLCs, so my apologies if this post is too vague.
