These modules provide an isolated Ethernet interface for any input/output mix of up to 16 discrete signals. Inputs sense status of dry contacts, switches, power supplies, and DC logic. Outputs control solid-state switching of lamps, horns, and other devices.

989EN-4C16: Commercial (no counters)
989EN-4016: Industrial-grade

Environmental

Operating Temperature Range
989EN-4016, -40 to 65°C (-40 to 149°F).
989EN-4C16, 0 to 55°C (32 to 131°F).

Storage Temperature Range
989EN-4016, -40 to 85°C (-40 to 185°F).
989EN-4C16, 0 to 70°C (32 to 158°F).

Relative Humidity: 5 to 95%, non-condensing.

Isolation: 3-way isolation of I/O, power, network circuits.
Peak: 1500V AC, ANSI/ISA-82.01-1988.
Continuous: 250V AC, 354V DC.

Communication

Connector: Shielded RJ-45 sockets, 8-pin, 10BaseT/100BaseTX.

Wiring: Wired MDI. 9xxEN I/O modules do NOT support autocrossover. 900EN switch supports auto-crossover.

Protocol: EtherNet/IP or Modbus TCP/IP with web browser configuration. EtherNet/IP supports PCCC object for communication with legacy PLCs (e.g. SLC505).

IP Address: Default static IP address is 128.1.1.100.

Port:
Ethernet Modbus TCP/IP models (9xxEN-4xxx): Up to 10 Modbus TCP/IP sockets supported.
EtherNet/IP models (9xxEN-6xxx): Up to 10 EtherNet/IP sockets and 1 Modbus TCP/IP socket.

Data Rate: Auto-sensed, 10Mbps or 100Mbps.

Duplex: Auto-negotiated, full or half-duplex.

Compliance: IEEE 802.3, 802.3u, 802.3x, Ethernet II.

Configuration: Web page for configuration and control is built-in with Ethernet access via a standard web browser.

Communication Distance: Distance between network devices is generally limited to 100 meters using recommended cable. Distances may be extended using hubs and switches.

Address: IP address is automatically acquired at startup. Unit may be configured to retrieve this address from the network server using BOOTP (Bootstrap Protocol), or via DHCP (Dynamic Configuration Protocol). A static IP address is also user-programmable. A default toggle switch sets the static IP address to the default factory address of 128.1.1.100 for initial configuration.

Environmental

Isolation: I/O channel, power, and network circuits are isolated from each other for common-mode voltages up to 250VAC, or 354V DC off DC power ground, on a continuous basis (will withstand 1500VAC dielectric strength test for one minute without breakdown). Complies with test requirements of ANSI/ISA-82.01- 1988 for voltage rating specified.

Electromagnetic Compatibility (EMC)

Immunity per European Norm EN50082-1. Emissions per European Norm EN50081-1.

Electrostatic Discharge (ESD) Immunity Per EN61000-4-2.

Radiated Field Immunity (RFI) Per EN61000-4-3 and ENV50204.

Electrical Fast Transient Immunity (EFT) Per EN61000-4-4.

Conducted RF Immunity (CRFI) Per EN61000-4-6.

Surge Immunity Per EN61000-4-5.

Radiated Frequency Emissions Per EN55022 Class B.

EtherStax Series

  • Description

    Acromag’s Modbus C Library software greatly simplifies development of programs to interface with Acromag’s BusWorks® and EtherStax® Ethernet I/O products. The library also supports any standard Ethernet Modbus slave device that communicates via Modbus TCP/IP or UDP/IP protocol. This utility is ideal for developers that are unfamiliar with Modbus protocol or the framing of TCP/IP or UDP/IP messages.

    The C library makes programming easy and portable by simply linking user code with the provided function calls (below). Most function calls require passing only a few parameters such as the IP address, Modbus register address, and
    register count.

    Codes | Functions
    01 (01H)  | Read Coil (Output) Status
    02 (02H) | Read Input Status
    03 (03H) | Read Holding Registers
    04 (04H) | Read Input Registers
    05 (05H) | Force Single Coil (Output)
    06 (06H) | Preset Single Register
    15 (0FH) | Force Multiple Coils (Outputs)
    16 (10H) | Preset Multiple Registers
    17 (11H) | Report Slave ID

    Example Program

    The included example program is menu-driven to help users build Modbus TCP/IP and UDP/IP commands. Menu selections let users configure, read, and write Ethernet I/O slave devices such as Acromag’s BusWorks and EtherStax products.

    Users may also leverage this demonstration application into a tool for configuration or test by supplying commands and/or data values in the form of a text file. The program will execute each command in the text file as if it had been typed from the console terminal.
