I/O : Tealware

Tealware I/O Rack

Tealware I/O

Tealware™ is a high density, modular I/O system, suitable for applications requiring as few as 16 digital and/or 4 analog points up through thousands of I/O points. The same I/O modules, racks, adapters, and other equipment can be used regardless of application size or physical configuration.

Tealware I/O can be used on Ethernet with any SoftPLC CPU, or with any other system that can drive ModbusTCP I/O.

Tealware on Smart Backplane3

With a Smart SoftPLC, high speed local I/O interfaces are available that support up to thousands of points, as well as remote Ethernet I/O for even more flexibility on I/O configurations.

  • Overview

    A complete range of I/O modules are available for the Tealware system - digital, analog, and specialty modules. Many common features of all modules make the system robust, and simplify installation and maintenance:

    • Detachable front-end terminal block for easy module replacement without re-wiring (some modules utilize a wiring cable connection, which is also easily detachable)
    • Front Panel LED display for status monitoring/troubleshooting
    • High noise immunity
    • Automatic Configuration - Module addressing based on location (not DIP switch) for easy system configuration & maintenance (manual configuration option also available)
    • Most modules are hot swappable under power
    • Low power consumption means all module configurations are possible - no power calculations required

    A wide variety of configuration options are possible including high speed local I/O and remote/distributed Ethernet I/O configurations.

    Available Tealware Modules

    A wide range of Tealware I/O modules is available - digital, analog, and special purpose modules. Combined with other components (eg: bases, adapters, power supplies), Tealware offers an expandable I/O system for both local and distributed control systems, big and small.

    Most modules include as standard the wiring terminal block. Some high density modules require a cable and terminal block to be ordered separately, as indicated in the tables below.

    System Configurations

    Tealware I/O modules mount into a backplane. There are 2 options for module mounting, (an example of each shown at the top of the page):

    • Up to (3) modules can be mounted directly to a Smart SoftPLC or Smart Adapter equipped with a Backplane-3 Interface.
    • I/O Bases can hold (6) or (8) modules plus a Tealware Power Supply Module, and connect via an Expansion I/O Cable (Cat No EXCBLxx) to a Smart SoftPLC or Smart Adapter equipped with a LocalPorts Interface.

    A Smart SoftPLC provides a high speed local interface to Tealware I/O. Up to 12 I/O Bases (96 I/O modules) are supported for a maximum of 3072 local I/O points, up to 30 feet from the Smart SoftPLC. You can scan thousands of points in under 1 msec!

    Smart Adapters provide a Tealware I/O Interface to remote I/O drops over Ethernet, connected to any SoftPLC controller or other controller that supports ModbusTCP. Where more I/O is required than a local system supports, or the I/O needs to be distributed over a distance, or where the control system CPU is not a Smart SoftPLC (eg: a SoftPLC Hardbook or non-SoftPLC controller), then Tealware modules can be used with Smart Adapters on ModbusTCP Ethernet in a wide variety of configurations/media, with up to 127 remote I/O drops of up to 24 modules (up to 768 I/O points) per drop - tens of thousands of I/O in a single system.

  • Two interface options are available:

    • Backplane3 Interface - Any three (3) Tealware modules can mount directly onto a Smart SoftPLC or Smart Adapter equipped with a Backplane3 Interface.
    • LocalPorts Interface - If more than (3) modules are needed at a location, a Smart SoftPLC or Smart Adapter equipped with a LocalPorts Interface is used. The LocalPorts Interface has (4) I/O Base ports. A Smart SoftPLC can utilize all (4) ports, a Smart Adapter can utilize (1) of the ports. Up to (3) I/O Bases can be connected to each port. I/O Expansion Cables, available in 2', 4', 6' and 10' lengths, connect from the I/O Base Port to an I/O Base (as well as from I/O Base to I/O Base).
