State Logic Programming

Last update on Sept. 5, 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.

Features include:

  • 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 ...

SDI-12 Interface for Micro SoftPLC

Last update on Sept. 5, 2015.

SDI-12 Interface for Micro SoftPLC

We now offer a "daughter-board" (Cat.No. SPBB-6DI2SP1AI) for the Micro SoftPLC, Model BB, that provides an SDI-12 interface, battery power connection and health monitoring, and six additional digital inputs.

This combination is a great solution for applications where monitoring, logging and reporting on environmental conditions is required. SoftPLC provides flexible data log file formats (eg: CSV, encrypted, customer specified)and storage options (eg: USB drive, SD flash and/or remote systems).  Add a modem and the Micro SoftPLC can cost effectively provide the sensor data via email or via our TagWell cloud platform to remote web pages, databases, or ...

Last update on Sept. 5, 2015.

Hot Standby System for SoftPLC ver 4.x

Now any version 4.6 or later SoftPLC with ModbusTCP I/O (including Tealware) can be used in systems requiring bumpless transfer hot backup controllers.  The solution includes a HOTBACK.TLM (firmware Cat No SPZ-HS) and a passive hardware component, called an Arbitrator (Cat No SPZ-HSA) which manages the Master/Backup status designations and I/O communication.

The Arbitrator includes redundant power input, and can provide redundant power output as well.  Click here for more information.
