Frequently Asked Questions

What is the article number of the IM 155-6 PN ST interface module covered in this manual?

The module covered is 6ES7155-6AU01-0BN0 (IM 155-6 PN ST interface module and server module). A bundle version that includes the BusAdapter BA 2xRJ45 is available under article number 6ES7155-6AA01-0BN0.

How many I/O modules can be connected to a single IM 155-6 PN ST station?

A maximum of 32 I/O modules can be operated per station. The station also supports up to 16 ET 200AL modules via ET-Connection and a maximum of 512 bytes of I/O data.

Which BusAdapters are compatible with the IM 155-6 PN ST?

Three BusAdapter types are compatible: BA 2xRJ45 for standard RJ45 connectors, BA 2xFC for direct connection of the bus cable, and BA 2xM12 for standard M12 or push-pull connectors.

What PROFINET IO functions does the IM 155-6 PN ST support?

The module supports an integrated 2-port switch, isochronous real-time communication (IRT), media redundancy (MRP), shared device (up to 2 IO controllers), prioritized startup, PROFIenergy, module-internal Shared Input/Shared Output (MSI/MSO), device replacement without programming device, configuration control, and station extension via ET-Connection.

What is the minimum update time for PROFINET IO communication?

The minimum update time is 1 ms. For IRT communication, send cycles between 250 µs and 4 ms in increments of 125 µs are supported.

What LED indicators are present on the IM 155-6 PN ST interface module?

The interface module has RUN (green), ERROR (red), MAINT (yellow), and PWR (green, supply voltage) LEDs. Two green link LEDs (LK1 and LK2) on the BusAdapter show the PROFINET port status.

What is the maximum reaction time of the IM 155-6 PN ST that must be considered when calculating fail-safe module reaction times?

The maximum reaction time of the interface module is the configured update time plus 400 µs, but at least 1.4 ms. This value must be included when calculating the overall reaction times of fail-safe modules.
