SIMATIC S7-1200 Basic Controllers
CM 1242-5
The CM 1242-5 communications module is used to connect
a SIMATIC S7-1200 to PROFIBUS as a DP slave and has the
following characteristics:
• PROFIBUS DPV1 slave in accordance with IEC 61158
• Module replacement without PG supported
• Power is supplied via the backplane bus so that no extra
cabling is required
• Support of all standard baud rates from 9.6 kbps to 12 Mbps
• Compact industry-standard enclosure in S7-1200 design for
mounting on a DIN rail
• Fast commissioning thanks to easy configuration using
STEP 7 without additional programming overhead
The CM 1242-5 is intended for use in factory automation.
Low-cost PROFIBUS-based automation solutions can be
created on the basis of the SIMATIC S7-1200 for optimal
production.
