More about selecting S7-400 communication modules parts
CP 443 Communication Processors
CP 443 processors connect the S7-400 to Industrial Ethernet, PROFINET, or PROFIBUS and, depending on the model, support, for example, S7 communication, PG/OP, SEND/RECEIVE, or integration with higher-level systems.
First, we need to know which network and protocol you are using. Based on that, we will determine the appropriate CP 443 for Industrial Ethernet, PROFINET, or PROFIBUS, the number of connections required, the firmware, and whether it is supported by your CPU and your STEP 7 project.
New, refurbished, and discontinued parts from our warehouses
For current SIMATIC S7-400 parts, we first verify the availability of new, genuine SIEMENS parts. We have access to an extensive network of industrial parts warehouses in Europe and around the world, which allows us to also check for refurbished, discontinued, and hard-to-find variants.
Diagnostics, Repairs, and Testing of S7-400 Components
You can send the defective part to FOXON for diagnosis. We perform repairs on CPUs, I/O modules, communication modules, functional modules, and power supplies at specialized repair centers; after repair, the parts are functionally tested under load. If repair is not feasible, we will check for an identical new or refurbished part or a compatible replacement.
