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

SoftPLC Web Studio version 8.1 has been released! This version includes expanded capabilities and also addresses a critical security vulnerability.
Existing customers can upgrade at no cost if the license was purchased on or after July 1, 2017 or if you have a current Maintenance Agreement. Reduced price upgrades are available to customers that purchased the license between Jan 1, 2017 and June 30, 2017. Free or reduced cost upgrades must be requested by March 8, 2018. If you don't qualify for the free/reduced upgrade, you can purchase the upgrade at 60% of license cost through March 8, 2018. Contact email@example.com, referencing your Registration Number(s), for more details and upgrade costs (if any).
Some new features in version 8.1:
- Support for all native objects in HTML5 (SMA Clients and IoTVIEW)
- OPC UA Server
- Streamlined Licensing - no restrictions on number of concurrent drivers or thin clients. Thin clients are now purchased per client, regardless of type needed.
- Improved Security
- Seamless Upgrade
Security Bulletin!!! Vulnerabilities were found in Web Studio version 8.0 Service Pack 2 Patch 1 and prior. It is recommended that customers review the bulletin to determine if their systems are at risk, and upgrade as soon as possible.

Due to a conflict with Ethernet/IP communications, we have changed the "Detect on Net" function to use a different Ethernet port.
TOPDOC NexGen version 1.6.160608 or later is required to successfully use the "Detect on Net" function with both older SoftPLC's and with SoftPLC's version 4.6.160608 and later.
Contact firstname.lastname@example.org for details on updating your TOPDOC NexGen.

Equip any SoftPLC CPU with a Web Studio Linux IoTView runtime and create an IoTPAC - a full-featured combination Programmable Automation Controller and SCADA platform. The new IoTView runs embedded in SoftPLC, communicating to the SoftPLC's data table via a RAM based driver. Add web browser based operator interface, sophisticated alarming, trending, and remote database access to any SoftPLC - including Micro's!
Many applications don't require a touchscreen to be present and can benefit in using a Smart Phone/Tablet based web browser as the user interface device - save cost, space and maintenance of a fragile touchscreen in harsh environments.

Products like SoftPLC Gateways are a key component in moving data to the cloud efficiently. Having complete and current data about any process can result in better decision making. One of the primary benefits of the Internet of Things (IoT), sometimes called the Industrial Internet, is that companies can make improvements in production processes, end products, and logistics that reduce costs and energy usage. By capturing and centralizing information from all the pieces/parts of production and doing so in a timely, automatic, non-intrusive manner, analytics programs can find places for these improvements.
This paper, authored by Cindy Hollenbeck, VP Marketing of SoftPLC Corp. was originally published in "Industrial Embedded Systems" magazine June, 2015.

The SoftPLC C++ Programmer's Toolkit has been enhanced to provide comprehensive support for State Logic Programming.
State Logic is a great way to apply C++ to control applications, while at the same time sharing measured and calculated variables with HMI's via our standard protocols. Finite State Machines (FSM) are known to be easy to troubleshoot because their "problem search space" is small and focused.
- State transition monitor for debugging.
- State dwell timer. Applicable to every state machine and every state tells how long any FSM has been in its current state.
- No limit to how many FSMs per TLM. No limit to how many TLMs with FSMs.
- FSMs from different TLMs can share variables by locating them in the datatable. Variables can be either private to TLM or shared in datatable.
- Shared variables can be bool, int16_t, float32_t, array of int16_t, array of float32_t, and structures.
