Smart Gateways

A Smart Gateway combines a basic set of features, to which you can add both hardware and firmware options. Smart Gateways are assembled with your selected options, then undergo a system-level test prior to shipment.

All Smart Gateways include this base set of 9 communication ports:

• 4-port 10/100MB managed Ethernet switch with two Ethernet interfaces (MAC ID's) to support routing and firewall functions
• One RS-485 + four RS-232 serial communications ports

For very low cost, these factory installed communication port options are also available:

• Additional RS-485 port, with 2 and 4-wire support (installs at COM6)
• Allen-Bradley Remote I/O Master or Slave (Up to 2 ports - replaces COM5 and/or installs at COM6)
• Allen-Bradley Data Highway Plus (Up to 2 ports - replaces COM5 and/or installs at COM6)
• CAN / J1939 (installs at COM6)
• Internal serial telephone modem (installs at COM6)

In some models you can add even more communication channels! Communication cards can be installed for support of industrial bus interfaces such as ProfiNet, Profibus, DeviceNet and others.

Available Models

Contact us for assistance in configuration OR use the simple webstore ordering page.

Select from the following to specify your Smart Gateway hardware configuration:

• COM5 Option
• COM6 Option
• SoftPLC Gateway License Size

To each of these combinations, you can then select additional firmware options to support advanced features such as data logging, an embedded web server, email/text messaging and more.

Hardware Options

Serial, A-B RIO/DH+ Options

Gateway License Size Options

There are (4) Gateway sizes, where the selected size determines the maximum supported number of ModbusTCP Servers (connections) and/or mapped digital I/O points (digital I/O limit only applies to A-B RIO/DH+ enabled Gateways, sized by the A-B definition of logical racks). If ModbusTCP or A-B drivers are not going to be used, select the LT size.

Examples

The table below illustrates some example Smart Gateway assembly catalog numbers.

A Smart Gateway is, in reality, a Smart SoftPLC. For more details on advanced features, additional hardware/firmware options and available accessories, refer to the Smart SoftPLC and universal SoftPLC features information.

Micro Gateways

SoftPLC's Micro Gateways are physically small, inexpensive options for simple serial to Ethernet bridging needs, such as ModbusTCP to Modbus serial. Like all SoftPLC Gateways, Micro Gateways provide data passing between networks, and also can be used for advanced functions like data logging, remote access and alarm notification.

Specifications:

• Memory - 512MB RAM
• Storage - 4GB onboard flash, MicroSD up to 8GB optional
• USB 2.0 host
• Micro USB 2.0 client (for power & communications)
  MicroUSB to USB cable included
• 10/100MB Ethernet port, RJ-45 connector
• Power by +5 VDC through barrel connector (eg: using ICO-PSW105) or USB device port
• Size - 3.4” x 2.1” (86.36 x 53.34 mm), With optional enclosure (Cat No SPBB-ENCL1) 2.4" x 0.82" x 3.54" (62 x 21 x 90 mm)

Micro Gateway Protocols:

Micro Gateways can be user configured for up to 16 simultaneous protocols of any mix, dependent only on the available hardware ports. The currently available protocols for model SPBB Gateways are listed below, others can be added by SoftPLC or by users with the SoftPLC Programmer's Toolkit. Please contact us for a quote if you are interested in a protocol not listed.

• ASCII (COMGENIUS)
• Modbus Serial RTU/ASCII, Master and Slave
• Modbus TCP/UDP Master (Client) and Slave (Server)
• Enron ModbusTCP Master (Client)
• A-B DF1 Serial Full Duplex, Half Duplex Slave

Micro Gateway Models & Options

Model No SPBBA1-x is a Micro Gateway Assembly with (1) Ethernet and (1) RS-232 serial port, in a metal enclosure (see photo above). Alternatively, you can specify an open-board-style Micro Gateway by ordering individual components to meet your needs for additional serial ports, hardware to support other protocols, add a modem for remote access, etc.

In either case, select the size capacity of your Micro Gateway using the table below.

Micro Gateway Options

• Firmware Options - software enabled capabilities that can be added to any SoftPLC Gateway. There's so many, we've put them on their own page! Examples include data logging, email/text messaging, embedded web server, and others.
• Hardware Options - The table below lists individual components you can mix/match for board-level Micro Gateway solutions.

Other SoftPLC Gateways

Any SoftPLC Hardbook can also be used as a protocol gateway. Each model includes multiple Ethernet, USB, and serial ports, and most can accomodate interfaces to industrial networks via add-on interface cards (Cat No SPO-PCx).

Gateway Applications

Uses for SoftPLC Gateway/Data Hubs are many and varied:

• Multiple protocols provides integration of different equipment and systems
• Ethernet gateway / data concentrator
• Data logging for tracking and troubleshooting
• Email/text alarms reduce downtime
• Automated data collection/reporting without an HMI/computer
• Remote asset management and control
