The ET 200SP distributed I/O system just further increased flexibility by adding an integrated three-port PROFINET switch to the latest version of the IM155-6PN/3 interface module. The IM155-6PN/3 connects the ET 200SP to the machine bus system. The extra switch ports are targeted at installations with outgoing PROFINET spur lines, for example for connections to HMIs or the Siemens Field PG notebook, or for cable drag. The interface module also supports integrated local I/O data coupling among up to four PROFINET I/O controllers.
The ET 200SP is a distributed controller and I/O system designed to capture and transmit data over PROFINET connections. The modular system consists of a PC-based software controller with integrated safety, the interface module, and up to 64 I/O modules. It can handle I/O for both simple and complex functions. As a result, the ET 200SP can be scaled to suit the demands of any particular machine and application. Once OEMs learn the system, they can apply that knowledge to platforms with a wide range of I/O needs. The ET 200SP also includes motor starters and frequency converters with failsafe functionality option.
The IM155-6PN/3 has extended functionality compared to incumbent offerings. The interface module provides module-to-module (MtM) communications within a single station through the ET 200SP backplane (see figure 2). This makes it possible to offload minor and/or time critical tasks to the I/O modules, increasing speed and reducing the computational burden on the CPU.
Other key features of the interface module include:
- Combination of shared device and isochronous mode
- Support of the time stamp for min-max values with HF Energy Meter
- Expansion of the ambient temperature range to -30 °C to + 60 °C (without condensation)
- Mains buffering time increased from 5 ms to 10 ms
- Under-voltage diagnostics for new enclosure
- Strain relief for PROFINET cable can be optionally mounted (6ES7193-6RA00-1AN0)
Module-internal shared output is transferred to other controllers (see figure 3).Have an Inquiry for Siemens about this article? Click Here >>
