All SoftPLC controller CPUs provide the same rich set of features. Every SoftPLC is a high-performance, feature-rich Programmable Automation Controller (PAC), combining the functions of a proprietary PLC with the benefits of both an open architecture design and computer technologies.

Some key features, which are included in every SoftPLC:

	Reliable solution for both process and machine control
	Deterministic, high speed program execution
	"Unlimited" memory for user logic and data table
	Ladder logic and data table addressing similar to Allen-Bradley PLC-5/SLC-500/MicroLogix
	Fully documented applications, all documentation resides in the SoftPLC controller
	Supports I/O systems and other devices from hundreds of vendors
	Supports a wide variety of protocols - ethernet, industrial network and serial
	Compatible with all HMI/SCADA products, including user generated PC based operator interfaces
	Supports user functions written in C++ or Java

Optional features can be added to any system:

	Embedded web server
	Embedded firewall with VPN

All SoftPLC's are programmed, configured, and maintained with TOPDOC NexGen programming software.

SoftPLC CPU's come in a variety of shapes and sizes:

Smart SoftPLC

Smart SoftPLC's are appropriate for applications ranging from small, low I/O count needs to large, distributed control systems. All Smart SoftPLC's have an embedded ethernet switch (w/ fiber option), 5 serial ports, embedded phone modem option, and a wide choice of I/O interfaces to SoftPLC's Tealware I/O, hundreds of other vendor I/O products via Ethernet and/or serial, or industrial bus interfaces such as Profibus, DeviceNet, etc.

SoftPLC in Tealware

SoftPLC In Tealware™ is an advanced, traditional hardware format controller system. Products include compact rack-mounted components such as CPU's, power supplies, and I/O modules. CPU bases can accommodate from 4 to 8 I/O modules, and both local and remote I/O expansion capabilities allow a single CPU to control up to 16,384 I/O points. SoftPLC In Tealware also supports redundant, hot-standby operation.

Hardbook Processors

Hardbook CPUs are compact, low-cost controllers that can handle most applications. Hardbooks are ideal for ethernet I/O applications, whether Tealware I/O or another vendor's I/O is used. Via included ports and expansion slots, the Hardbooks support a wide range of I/O serial devices and third-party products.

SoftPLC Processors

SoftPLC Processors™ are CPU's that are available with a wide variety of expansion options. There is virtually no limit as to system capacity or possible configurations.

RTU's

SoftPLC RTU's are designed specifically for remote and distributed installations. The SoftPLC TagWell System provides cloud-based monitoring, data acquisition, reporting, and alarming services via a combination of the Internet and cellular networks. Our Smart RTU products are suitable for most applications. For extremely harsh environments or specialized requirements, our SC products can meet the challenges.

TOPDOC

Programmer's Toolkit

If you have a fairly good understanding of C or C++, you can create your own ladder instructions, device drivers, and more with the SoftPLC Programmer's Toolkit. The Toolkit includes a description of our API (Applications Program Interface), example source code, "helper" functions, and a detailed programming manual.
