2.2 Functions
Introduction
The interface module supports the following PROFINET IO functions:
• Integrated switch with 2 ports
• Supported Ethernet services: ping, arp, SNMP, LLDP
• Port diagnostics
• Disabling ports
• Isochronous real-time communication
• Minimum update time 1 ms
• Prioritized startup
• Media redundancy (MRP)
• Shared device
• Support of submodules on suitable I/O modules
• Module-internal Shared Input/Shared Output (MSI/MSO)
• Device replacement without PG and without topological configuration
• Reset to factory settings via PROFINET IO
• Firmware update via PROFINET IO
• Station extension via ET-Connection
• The BusAdapter provides the connection system for PROFINET IO. The following versions
are available for the IM 155-6 PN ST interface module:
– For standard RJ45 connector: BA 2×RJ45
– For direct connection of the bus cable: BA 2×FC
– For standard M12 connector or push-pull connector BA 2xM12
The interface module supports additional functions:
• Identification data I&M 0 to 3
• PROFIenergy
• Use of fail-safe modules
• Configuration control (option handling)
• Value status (quality information, QI) of I/O modules
not use the IM155-6 PN ST interface module as a docking station. The use as a docking
unit (function: IO devices changing during operation) in a docking system is supported.
