Programming the IP 265 with COM 265

COM 265 Language Description

The IP 265 user program is written with the aid of COM 265 in a control system flowchart (CSF)
format similar to that used in STEP 5 (for programming SIMATIC CPUs).
In contrast to the CPU user program, the IP 265 user program is not subdivided into blocks which
have to be called during program scanning. The IP 265 user program's control system flowchart is
comprised only of segments. Segments are editing aids, and do not prescribe the order in which the
IP 265 is to process them.
A segment in an IP 265 user program
You program the segments yourself with the COM 265 editor. The editor numbers the segments.
Each segment consists of
• a logic field with COM 265 language elements (such as logic operations, timer operations,
counter operations, and so on) and connecting lines
• one input and one output bar (margin bars) with operands.
