In Stock: A-B RIO/DH Gateways

Written on June 23, 2022 in A-B PLC Migrations, Support , Communication .

Last update on March 30, 2023.

We provide gateways to provide communication between devices on Allen-Bradley Remote I/O (RIO) or Data Highway Plus (DH+) networks and devices on other networks such as Ethernet/IP, ModbusTCP, DF1, Modbus serial and others, and both models are in stock:  our Smart and NeoPAC SoftPLC Gateways.

ProSoft Discontinued RIO/DH+ Gateway

ProSoft Technology recently discontinued their AN-X2-AB-DHRIO product, which was the only other supported gateway on the market.  SoftPLC Gateways provide more functionality than the ProSoft model (see the "Compare" tab at http://softplc.com/products/comm/abgw_landpg/) and are value priced options for customers needing "blue-hose" communications for partial system upgrades.

New Video - Control System Migrations

We've added a new video to our library.  This one discusses how SoftPLC Gateways can help A-B PLC users use phased migrations to upgrade their system vs complete retrofits.  Phased migrations reduce cost, downtime, and risk among other benefits.

Peer-to-Peer Messaging thru the Cloud

Written on Feb. 20, 2020 in Communication , News, Events, Misc , TagWell, IoT, M2M .

Last update on Feb. 20, 2020.

Our TagWell platform has been enhanced to support some exciting new features!

Firstly, remote nodes can send data to each other via the TagWell cloud platform.  Similar to PLC Messaging, any TagWell remote node can send /receive data arrays to/from any number of other remote nodes.  These secure communications are optimized to transmit only upon data changes to minimize cellular communication costs.  Since the remotes are SoftPLC controllers or gateways, via logic data changes can be forced if the user wants the messages to be sent based on time or other specific events.

Secondly, the TagWell platform now supports ...

Last update on July 11, 2016.

Due to a conflict with Ethernet/IP communications, we have changed the "Detect on Net" function to use a different Ethernet port.

SoftLC now supports DHCP address assignments

Written on July 24, 2012 in Communication , SoftPLC Hardware/Software .

Last update on Sept. 5, 2015.

SoftPLC’s networking now can support DHCP as an alternative to BOOTP and static IP addresses.

To use a DHCP client on any SoftPLC ethernet interface, just have the line in NETWORK.LST say:

ETH DHCP

That’s it!  The DHCP server should establish the GATEWAY and the DNS settings, the values in NETWORK.LST will be ignored if DHCP is set for an interface.

This support is for SoftPLC versions 4.6 and later.  Contact technical support (support@softplc.com) for more information.
