The NXEE2
The NXEE2 is a two channel SSI interface module that accepts 24 to 48 Vdc as its power source.
Synchro-
nous Serial Interface
(SSI) is an industry standard serial protocol for transmitting sensor data. The SSI proto-
col is most commonly used in rotary and linear distance sensors, but any type of data can be transmitted using
the protocol.
The NXEE2 is a two channel SSI interface module that allows you to lower transducer wiring cost by placing
the NXEE2 close to the transducers and running a single network cable back to the host controller. The
NXEE2 also future-proofs your SSI feedback design. The host controller can be updated to any future plat-
form that supports EtherNet/IP, PROFINET, or Modbus TCP and the NXEE2 will operate with the new sys-
tem.
E2 Technology
The NXEE2 is a member of the growing line of products from AMCI that incorporate our
E2 Technology
. E2
Technology by AMCI is an innovative new multi-protocol approach to Ethernet distributed I/O.
E2 Technology products are simple and intuitive, allowing easy transition between Ethernet/IP, PROFINET,
or Modbus/TCP protocols without the need to physically switch parts. An advanced web server integrated
into all AMCI E2 Technology devices facilitates simple network configuration and troubleshooting via a
web-browser. Furthermore, an impressive array of advanced features for each supported protocol has been
incorporated into the devices to meet many unique application requirements.
Each unit has two Ethernet ports which are internally connected through an onboard, two port, 10/100 Mbps
ethernet switch. These ports allow you to wire your network in a “daisy-chain” fashion, which may lower net-
work wiring costs and complexities.
The two ports also allow the units to function as members of a redundant Device Level Ring (DLR) network
when using the EtherNet/IP protocol or as clients in a Media Redundancy Protocol (MRP) network when
using PROFINET.
In DLR environments, the units act as Beacon-Based Ring Nodes. All units can process beacon packets at the
default rate of every 400 microseconds. Beacon-based nodes can respond faster to network changes than
nodes that only process Announce packets.
SSI Sensor Interface
The NXEE2 contains several parameters that allows the module to interface with any SSI sensor on the mar-
ket today and extract the data value from it. A total of four values are available. These four values are:
Data Value (Typically a position value.)
Rate of Change (The velocity value when the Data Value represents a position.)
Actual SSI Value (The data stream read from the SSI sensor. This stream will include any available
status bits.)
Captured Data Value (Captures and reports the Data Value when an input makes a transition. The
NXEE2 sets a status bit to signal that a new value is available. This bit must be reset by a write to the
NXEE2 from the host controller before another capture can occur.)
Any two of these values can be reported to the host controller at a time. The two that are reported is program-
mable from the host controller.
Each channel has a dedicated DC input. As mentioned above, the input can be programmed to capture the
Data Value on a transition. The input can also be programmed for a different function. The input can be pro-
grammed to preset the Data Value on a transition. The Preset Value is programmable from the host controller.
This reference section contains the information you need to decide if the NXEE2
SSI Interface Module is the right product for your application.
