The IM 155-6PN High Feature is designed mainly for PROFINET applications with a high, flexible demand for functions, as well as a large station expansion of up to 64 modules (max. 1024 IO signals). All I/O modules, including PROFIsafe, can be used. In addition, the station can be expanded with as many as 16 IP67 modules of the SIMATIC ET 200AL series using BA-Send/BU-Send.

Unlike the other interface modules, the IM 155-6PN/2 HF supports the following additional functions:

Use of BusAdapters, also with fiber-optic cable connection
Increased data volume of up to 1440 bytes for both input and output data and up to 288 bytes per module
Multi Hot Swap (withdrawing and insertion of any number of I/O modules during operation without impairing the communication with the remaining modules)
S2 redundancy
Isochronous mode from 250 µs
Oversampling
MSI/MSO
Shared device with up to four controllers
Up to four subslots per module

With its third port, the 3-port IM155-6PN/3 HF interface module allows the expansion of the PROFINET topology by a spur line. Typical applications are:

Connection to a higher-level network
Programming device access in the field
Cable outlet via festoon cable system

The local IO data coupling allows data to be exchanged between up to 4 controllers quickly, deterministically, and without elaborate configuring.

IM 155-6PN High Speed PROFINET interface module

The IM 155-6PN High Speed is designed mainly for PROFINET applications with very short response times. All I/O modules, including PROFIsafe, can be used.

Compared to the IM 155-6PN HF, the IM 155-6PN HS has the following functional differences:

For input and output data with up to 32 bytes per module, max. 30 modules per station
Isochronous mode from 125 µs
MRPD
PROFINET Performance Upgrade (Fast Forwarding, Dynamic Frame Packaging, Fragmentation)

IM 155-6DP High Feature PROFIBUS interface module

The IM 155-DP High Feature is designed mainly for PROFIBUS applications with average station expansion of up to 32 modules (max. 512 IO signals). All I/O modules, including PROFIsafe, can be used. In addition, the station can be expanded with as many as 16 IP67 modules of the SIMATIC ET 200AL series using BA-Send/BU-Send.
