"End of an Era" - Lee is Retiring

June 25, 2021

Lee Parmeter, who has been with SoftPLC Corporation since 1987 is retiring at the end of June, 2021.  Most of our customers have interacted with Lee over the years in his role as head of Technical Support.  What you may not know is all the other things he did at SoftPLC like product & system testing, selecting hardware and components for our products, application and TLM programming, customer training and even system integration.  His decades of knowledge of PLC's and ladder logic, computer operating systems, computer and I/O hardware, I/O bus networks and more will be sorely missed.

You can send messages to Lee at and we will forward them if they arrive after his last day.

New Video - Control System Migrations

May 27, 2020

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. or

Peer-to-Peer Messaging thru the Cloud

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 data aggregation across any number of remotes into a single Tag Table in the cloud.  This makes it easier for a web interface or connected application, such as Web Studio or other software programs, to provide consolidated data for a group of and/or all of a customer's remotes.

SoftPLC NeoPAC now available!

Jan. 1, 2020

A new family of SoftPLC controllers and gateways is now available - the NeoPAC.

Packed with the features of our other SoftPLC's, the NeoPAC provides a powerful platform for:

  • Machine control - Great for OEM's!
  • Protocol Converter - serial to ethernet and/or to Allen-Bradley "blue hose" Remote I/O or Data Highway Plus
  • Cellular RTU - Combined with TagWell, you can monitor and control remotely located systems at very low cost
  • Data Logger
  • and more!

The NeoPAC is the lowest cost option for Allen-Bradley PLC migrations and RIO/DH+ gateways on the market.  It also can be used with serial/ethernet/USB I/O from hundreds of vendors.

Enhanced Ethernet/IP Driver for SoftPLC v4.6

Nov. 2, 2018

Now Available for all SoftPLC controllers version 4.6 and later is an enhanced Ethernet/IPTM driver.  SoftPLC can act as an Ethernet/IP generic device (adapter), or as a scanner (master).  A SoftPLC can also be used to simulate a Logix PLC for simulation/testing/training purposes.  Features of the Ethernet/IP driver include:

  • Five millisecond timing granularity
  • I/O scanner: up to 128 total originating i/o connections to as many target slaves as needed.
    • each i/o connection may have its own forward open timeout, RPI timeout multiplier, connection type, connection trigger type,
    • each i/o connection half may have its RPI, size, target and originating assembly, and realtime format.
  • Up to 2048 I/O connection bytes (determined by the size of the SoftPLC runtime license)
  • Up to 20 target i/o connections in the form of exclusive owner
  • Up to 3 input only i/o connections
  • Up to 2 listen only i/o connections
  • I/O connections may be unicast or multicast
  • Explicit messaging server supporting:
    • assembly class 0x04 instances
    • symbol class 0x6b instances -  This lets a SoftPLC runtime look like a Rockwell PLC/PAC to HMI's. A descriptor tag may be exported as a CIP symbol and it is tied to a unique assembly instance when exported.
  • Up to 1000 words per assembly
