IP 265
8 Fundamentals of COM 265
The COM 265 programming package is a user-friendly software aid for starting up the IP 265.
COM 265 is used both to write the IP 265 application program and to execute that program on the
IP 265.
Like other SIMATIC COM packages, COM 265 is an autonomous package. Conventional COM
packages are used to initialize SIMATIC S5 modules. In contrast, COM 265 has its own pro-
gramming language (based on the CSF format used in STEP 5) for writing and testing a special
application for the S5-100's IP 265 module. COM 265 thus has its own utilities and editors, similar to
the S5 utilities and STEP 5 packages used for CPU programming.
COM 265 can execute on the PG 730, PG 750 and PG 770 programmers as well as on AT-
compatible personal computers (PCs). Hardware and software requirements are listed in Table 8-1.
Table 8-1. Hardware and Software Requirements for COM 265
Operator Servicing Hardware requirements for PG and PC
• 80386 CPU
• 4 MB RAM
• Hard disk with free space totalling 5 Mbytes
• MS-DOS 3.2
• S5-DOS/ST (MS-DOS): V3.2
Section 8 begins with descriptions of fundamental COM 265 handling procedures in order to
acquaint you with the software package. You will find information on
• COM 265 installation and startup ( Section 8.1)
• Screen layouts for interactive screen forms ( Section 8.2)
• COM 265 basic functions in the "Function Selection" form ( Section 8.3)
• The hierarchical structure of COM 265 ( Section 8.4) and
• General COM 265 operator servicing procedures ( Section 8.5)
Note
All information on COM 265 operator servicing presented in the following sections relates to its use
on the PG 750 programmer. You will find additional information on the use of COM 265 on PCs in
Appendix D.
