Configurations:

Tealware CPU (SPLC-2A)

CPU Bases can accommodate the power supply module, CPU or I/O Adapter module and 4, 6, or 8 I/O modules. A typical SoftPLC in Tealware system consists of:

• A CPU base and optional expansion I/O bases
• CPU module with embedded SoftPLC Control Software
• Power supply module
• Various I/O modules

Expansion I/O bases for 6 or 8 I/O modules are available. You can connect up to 3 expansion bases to any CPU base. The maximum distance from a CPU base to the last expansion base is 30 feet. A local configuration can support up to 1024 I/O points.

Tealware Remote CPU (SPLC-2A/R)

SoftPIPE™ provides a 2.5MB remote I/O network connection. You can connect up to 15 remote drops, each consisting of a remote drop base (with Remote I/O Adapter) and up to 3 expansion I/O bases for a total of 64 racks. The maximum distance from the CPU and the last remote drop is 20,000 feet. Remote configurations can support up to 16,384 I/O points.

Hardbook or SoftPLC Processor CPU

Ethernet Remote I/O Adapters provide a Modbus TCP connection to remote Tealware I/O. Each remote drop can consist of a remote base with an Ethernet I/O adapter and up to 3 expansion I/O bases. You can connect up to 4 remote drops.

In both SoftPIPE and ethernet remote I/O configurations, fiber optic network connections are available via converters, for longer distances or more reliable communications in noisy environments.

With this system, a main CPU continuously transfers data table values to the backup standby CPU. The two CPU's are connected via a cable between Hot Standby modules which monitor the "health" of each CPU and assist with the data table value transfers. In the event of a main CPU failure, the backup will immediately begin processing with valid data.

For more details on the Hot Standby Feature, download this powerpoint presentation.

Tealware CPU modules, models SPLC-2A (local I/O only) and SPLC-2A/R (with remote I/O port), all include 16MB RAM, 16MB Flash, 2 serial ports, a 10MB ethernet port, operating mode keyswitch and status LEDs. All Tealware CPU Modules also include pre-installed SoftPLC Control Software. See the CPU specification sheet.
