The SIMATIC ET200SP product line, part of Siemens’ ET200 distributed automation platform, offers a high level functionality in a compact footprint for applications both inside and outside of the control cabinet. Due to this flexibility in ET200SP applications, there are a variety of modules (distinguished by “function class” that affect the application and expansion capabilities. Below is an overview of the different ET200SP hardware components, what their different function classes are, and what applications these classes apply to.
Interface Modules (IMs)
Each interface module (IM) in the ET200SP product family will display a two-letter notation on the front of the interface module, reflecting one of four function classes to which that module belongs. The different function classes listed below reflect an increasing level of functionality and expansion capabilities.
Basic (BA): allows for expansion of up to 12 modules, 2x Ethernet ports, works with all except fail-safe modules, allows for operation with gaps
Standard (ST): same features as Basic IMs, with the additional ability to support up to 32 modules, fail-safe hardware, IP 67 environments, and single hot swapping
High Feature (HF): same features as Standard IMs, with the additional ability to support up to 64 I/O modules, flexible connections via Bus Adapters, isochronous operating mode of 250 μs, and multi hot swapping
High Speed (HS): allows for expansion of up to 30 modules, with the additional ability to support isochronous operating mode of 125μs.
Central Processing Units (CPUs)
In addition to the features included with the aforementioned interface modules, the ET200SP CPU contains an integrated S7-1500 processor, thus allowing for high-level automation capabilities in a small footprint.
ET200SP CPU: allows for expansion of up to 64 I/O modules, contains integrated S7-1500 processor and onboard web server, and local data backup capabilities via a SIMATIC memory card
Each I/O, communication, and technology module in the ET200SP product family will display a two-letter notation in the top right corner of the module, reflecting one of four function classes to which that module belongs. The different function classes listed below reflect an increasing level of functionality or specific use case for the module.
Basic (BA): basic diagnostics and functions
Standard (ST): adjustable through parameterization, module-based diagnostics, faster processing of data
High Feature (HF): channel-based diagnostics, additional operating modes and functionalities
High Speed (HS): isochronous operating mode, highest speed of processing of data
