What If There Is An Ip 265 Overload - Siemens SIMATIC S5 Manual

IP 265
9.5.2

What if there is an IP 265 Overload?

If COM 265 aborts the compiler run because the IP 265 user program is too big, you can assess the
best measures for compressing the program by adding up the percent values shown in Table 9-13.
The following measures are recommended when the 100 % load limit has been exceeded:
• If parameters have been used in the IP 265 user program, check the following:
- Were the direct addresses of binary parameters chosen with care? Groups of bit parameters
should be combined into a byte!
- Can the parameter initialization of timer/counter or Compare operations be replaced by the
use of constants?
• If 24 V inputs have been configured for debouncing in the IP 265 user program, check to see
whether the direct addresses of the debounced inputs can be made part of one of the following
address groups:
- I 0.y with y=0, 1, 3, 7 or
- I 0.y with y=2, 4, 5, 6
• Consider whether some parts of the IP 265 user program could be optimized to put less load on
the IP 265 ( Section 13.2, "Programming Aids").
Other measures:
• Switching back and forth from "Compiler" to "Editor"
The compiler level has no provisions for editing functions such as changing an operand identifier
or deleting a language element, but it is still possible to make any necessary changes quickly
and easily:
You can switch back and forth between the Compiler and the Editor.
