It connects the S7-400 to PROFIBUS networks, supporting FMS, S5-compatible PG/OP, and S7 communication. This is the conformal-coated, extended-temperature variant (0 to +60 °C) of the standard 6GK7443-5FX02-0XE0, rated for harsher environments. ## Integration and configuration It occupies one single-width slot on the S7-400 rack, drawing 1 A typical at 5 V from the backplane bus, with a power loss of 5.5 W. The 9-pin Sub-D socket provides the RS485 PROFIBUS interface. Configuration requires STEP 7 V5.2 SP1 or higher and NCM S7 for PROFIBUS. Some features are dependent on the CPU type, so verify CPU compatibility against the note in the hardware catalog. ## Environmental ratings As a SIPLUS part, the module carries a conformal coating and is tested for resistance to commercially available cooling lubricants and airborne diesel and oil droplets. It conforms to EN 60721-3-3 Class 3S4 (including sand and dust) and Class 6S3 for transport/storage. The supplied plug covers must remain on unused interfaces during operation. Classification is IP20. Marked as a spare part, but the lifecycle stage is current. No imminent obsolescence.","metaTitle":"Siemens SIPLUS CP 443-5 Basic, PROFIBUS, 6AG1443-5FX02-4XE0","metaDescription":"SIPLUS NET CP 443-5 Basic for S7-400, based on 6GK7443-5FX02-0XE0, conformal coating, 0-60°C.
