Summary:

When using the PROSEC driver and displaying a page which generates requests for a block of more than 32 digitals, the "Request Size Too Big" error occurs. Why is this?

Solution:

CIT has confirmed this to be a problem with the PROSEC driver. This problem has been fixed in PROSEC driver version 2.05. With this fix, the driver is now able to read or write up to 32 registers in one request.
