IM 155-6PN High Feature PROFINET interface module

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.
