Specifying The Operator Stations; Creating The Configuration Drawings; Creating A List Of Symbolic Names - Siemens SIMATIC S7-200 System Manual

Basic Concepts for Programming an S7-200 CPU

Specifying the Operator Stations

Based on the requirements of the functional specifications, create drawings of the
operator stations. Include the following items:
Overview showing the location of each operator station in relation to the
process or machine
Mechanical layout of the devices (display, switches, lights, etc.) for the operator
station
Electrical drawings with the associated I/O of the CPU or expansion module

Creating the Configuration Drawings

Based on the requirements of the functional specification, create configuration
drawings of the control equipment. Include the following items:
Overview showing the location of each CPU in relation to the process or
machine
Mechanical layout of the CPU and expansion I/O modules (including cabinets
and other equipment)
Electrical drawings for each CPU and expansion I/O module (including the
device model numbers, communication addresses, and I/O addresses)

Creating a List of Symbolic Names

If you choose to use symbolic names for addressing, create a list of symbolic
names for the absolute addresses. Include not only the physical I/O signals, but
also the other elements to be used in your program.
