Labeling Sheets
• Labeling sheets that can be printed by machine for the I/O modules of SIMATIC
S7-400, including FMs, are the prerequisite for professional, convenient labeling
of SIMATIC modules.
• The labeling strips are already perforated on DIN A4 sheets and can be easily
separated without the use of a tool. This makes them easy to use and ensures a
clean cut.
• The labeling sheets are single-color, tear-proof and dirt-resistant. They are
available in petrol, light beige, red, and yellow.
• SIMATIC S7-400 I/O modules can be easily labeled application-specifically by
machine using a standard laser printer in one of the following two ways:
– Using templates that can be downloaded free from the Internet
– Using the “S7-SmartLabel” add-on tool for SIMATIC STEP7
