It connects an S7-1200 CPU to a PROFIBUS network as a DP slave, supporting both DPV0 and DPV1 profiles — so it handles cyclic data exchange and acyclic parameter/configuration data from a Class 2 master. The conformal coating and compliance with EN 60721-3-3 class 3S4 (including sand and dust) and class 6S3 mean this module is built for environments where airborne particulates, diesel mist, and cooling lubricants are present — not just a standard IP20 office-PLC module. It draws 0.15 A typical from the 5 VDC backplane bus, dissipating 0.75 W — well within the S7-1200 power budget, even with three such modules per CPU. The 9-pin Sub-D RS485 interface is the standard PROFIBUS connector; the supplied plug covers must remain over unused interfaces during operation to maintain the environmental seal. ## Panel fit and mounting constraints Single-width compact module, 30 mm wide, 100 mm high, 75 mm deep — snaps onto a 35 mm top-hat DIN rail or can be wall-mounted. Requires STEP 7 Basic V11.0 or higher for configuration; no Industrial Ethernet interface on this module — it is PROFIBUS-only.","metaTitle":"Siemens 6AG1242-5DX30-2XE0 SIPLUS CM 1242-5, DPV0/DPV1","metaDescription":"Active Siemens SIPLUS S7-1200 CM 1242-5 PROFIBUS DP slave module, conformal coated, -25 to +55°C, DPV0/DPV1.

They are important components in a holistic industrial security concept. Siemens products and solutions undergo continuous development with this factor in mind. Siemens recommends strongly that you regularly check for product updates. For the secure operation of Siemens products and solutions, it is necessary to take suitable protective measures (e.g. cell protection concept) and integrate each component into a holistic, state-of-the-art industrial security concept. Third-party products that may be in use should also be considered. You can find more information on Industrial Security at http://www.siemens.com/industrialsecurity. In order to keep yourself informed about product updates, we recommend subscribing to our product-specific newsletter. You can find more information on this at http://support.automation.siemens.com.
