Errors occurring when setting the "KFa,b" or "KFa.b" format parameters have the following

effects:

• If you specify values outside the value range for "a" and "b", the spaceholder is treated as text

and printed as configured.

• If you configure "a" with a value too small for the variable values to be printed, "?" characters

will be printed instead of the variable value.

"KG" and "KGa.b" data formats

You can print out a 32-bit floating-point number in the message text. A floating-point number

requires four bytes of memory.

Note:

In the S5-135U, floating-point numbers have only a 16-bit mantissa. Bits 0 to 7 (byte n + 3) are

always 0.

Floating-point numbers can be used in the S5-115U if the standard function blocks for floating-

point arithmetic are used.

The value for the floating-point number can be transferred as follows:

• In bytes 2 to 5 if the spaceholder is the only one or the first one in the message text.

• In bytes 4 to 7 if the spaceholder is the second one in the message text.

In addition, the memory requirement of four bytes has the following effects:

• Only one spaceholder per message text can be initialized in KG or KGa.b for "Insert floating-

point number". A second spaceholder of this type would be interpreted as text and printed as

configured.

• In addition to a spaceholder for "Insert floating-point number", only one further "KV" or

"Insert variable" spaceholder can be configured per message text.
