About the Book
At a Glance
Document Scope This Guide describes the hardware and software features of the Advantys
STB NIP 2212, which enables an island of Advantys STB modules to function as a
node on an Ethernet LAN.
The Ethernet LAN on which an island resides uses Transport Control Protocol/
Internet Protocol as its transport layer. The Modbus protocol runs over the TCP/IP
layer. This way, an Ethernet host device can control an island with Modbus
commands. The Modbus protocol allows devices that can connect only to the RS-
232 port on other Advantys STB NIMs to connect to the STB NIP 2212’s fieldbus
port, too.
The following information appears in this guide:
z the role of the standard NIM as the gateway between Ethernet TCP/IP and the
Advantys STB island
z the NIM’s integrated power supply and its role in the distribution of logic power
across the island bus
z
common external interfaces:
z
the two-pin connector to an external SELV-rated power supply
z
RS-232 interface to optional devices, including the Advantys configuration
software and an HMI panel
z the optional removable memory card
z advanced configuration features, such as island fallback scenarios
z STB NIP 2212 specific features, including its global connectivity capabilities
z how to configure an STB NIP 2212 with IP parameters
z
how to connect the STB NIP 2212 to an Ethernet network
z STB NIP 2212 web-based configuration and troubleshooting features
z SNMP management services
Who Should Use This Manual?
This manual is intended to support the customer who has installed the
Advantys STB island bus on an Ethernet LAN and needs to understand the
STB NIP 2212’s local and remote communications capabilities.
This manual assumes familiarity with the Modbus protocol.
