Position Decoding IP 240
Note
Scratch flags and system data areas are used in the standard function blocks for the
purpose of data interchange with the IP 240 ( Technical Specifications for the
FBs).
You must therefore
• save these flags and data areas at the beginning of the service routines for the
S5-115U, S5-135U (when set for interrupt servicing at block boundaries) and
S5-115U (155U mode) and reload them at the end of these routines.
• save these flags and data areas at the beginning of the restart (OB21/OB22) of
the S5-135U (with basic setting for the restart mode) and reload them at the
end of these routines.

The specified processing times are for an FB call following an IP 240 firmware cycle without data interchange. Note
that
• when data have been read from the IP 240, further data interchange in the same firmware cycle is disabled.
• when new data have been written to the IP 240, further data interchange in the same and in the next cycle is
disabled.
