PROFIBUS-based systems can be operated effectively for lower operating and maintenance costs:

• Low costs since an automation solution requires no fixed wiring and less hardware
• Fast response to faults thanks to comprehensive diagnostics options
• Optimized plant and inventory management

The CM 1242-5 also offers further benefits especially for the requirements of micro-automation solutions:

• Uncomplicated connection of the S7-1200 to PROFIBUS without extra power supply
• Low-cost implementation of automation solutions based on PROFIBUS
• Fast commissioning, as no programming overhead is required
