STB NIP 2212 Product Overview
Introduction An Advantys STB island bus configured with an STB NIP 2212 standard NIM can
function transparently as a node on an Ethernet local area network (LAN), or on the
Internet. It can function, indirectly, as a node on a wide area network (WAN). The
STB NIP 2212 can be a slave device to an Ethernet host manager.
Ethernet and
Internet
Connectivity
TCP/IP is the transport layer for the Ethernet LAN on which the STB NIP 2212
Advantys STB island resides. This network architecture enables communications
with a wide range of Ethernet TCP/IP control products, such as Programmable Logic
Controllers (PLCs), industrial computers, motion controllers, host computers, and
operator control stations.
The STB NIP 2212 NIM has a Transparent Ready implementation classification of
B20.
Embedded Web
Server
The STB NIP 2212 includes an embedded web server (See STB NIP 2212 Web
Server, p. 65), which is a web browser-enabled application. It allows authorized
users worldwide to view configuration and diagnostic data for the STB NIP 2212
(See Web Access Password Protection, p. 86). (Users with additional authorization
(See Configuration Password Protection, p. 89) can write data to the
STB NIP 2212.)
Internet
Applications
The STB NIP 2212 is configured for the following Internet applications:
HTTP embedded web server
–Port 80 service access point (SAP)
–browser based IP configuration and troubleshooting
SNMP—allows remote network management of the STB NIP 2212
–Port 161 SAP
–enables remote network management (NMT) of the STB NIP 2212
Open Modbus An open implementation of the proprietary Modbus protocol runs over TCP/IP on the
Ethernet LAN on which the STB NIP 2212 resides. The fieldbus (Ethernet) port (See
STB NIP 2212 Network Interface, p. 26) on the STB NIP 2212 is configured for Port
502 SAP functionality. Port 502 is the well-known port for Modbus over TCP that
was assigned to Schneider Electric by the Internet Authority (IANA).
