The EZ220-PLC and EZ420-PLC Series has been discontinued. Please see the OCSXL Series as a possible alternative or contact our Automation Engineering department.
The Most SENSIBLE One-Piece
Automation Controller for a Small Machine!
What is EZTextPLC? EZTextPLC is the most powerful combination of a
PLC and an Operator Interface in a very compact
package. It utilizes EZPLC’s base and thus capable
of all the features present in our EZPLC and uses
our ‘mix-match’ modular EZ I/O to deliver a truly
Where does it make sense? EZTextPLC can be used to configure a small
control system that requires a Text type display. It
eliminates the need to buy and install a PLC and
Operator Interface separately and thus reduces
the electrical panel space, makes the control
system extremely compact and cost effective.
With EZTextPLC starting at $482 for a 32 Digital
I/O system (16 Dig In/16 Dig Out), it is built to
compete in the market of Embedded controllers
without the hassle of "C" level programming or
proprietary microprocessor boards. EZTextPLC
uses EZ I/O modules for I/O (starting at $31 for
8 Digital Out!) which can be chosen from a large
variety of options including Analog I/O, High
Speed Counter, Relay, Thermocouple, RTD,
and AC/DC combo modules.
With PLC Performance You Will Find Only in
PLCs Costing Thousands More!
64k Byte User Memory Most Micro PLCs have only a limited 8-16k memory. But not this souped
up PLC! Some of the things you can do with this 64k byte memory:
Store 2000 Messages
Store 500 20-Variable Recipes
Collect 10,000 Four-Variable Data Points
32 Bit, 40 MHz RISC Processor
Dedicated to PLC Processing Only,
with a Separate Processor for HMI The EZText PLC has two processors, one for handling the
PLC and its I/O, and another co-processor for handling the
HMI functions. Even though the two processors cost more,
we wanted to make sure that you have one of the fastest PLCs
on your machine. This Text Panel PLC rivals scantime
specifications of the fastest full-blown PLCs.
Configuration Screen The EZText Enhanced programming software
is a Windows-based program. The EZ-to-use screens and
pull-down menus provide all tools you will need to select the
panel type, configure the PLC communications, create text
messages, etc. The EZText panels use simple addressing and bit
Competitor text panels require extensive programming and
associated ladder logic to make the pushbuttons and LEDs
Configuring Pushbuttons and Leds The configuration screen contains all of the information needed to configure
the pushbuttons and their associated LEDs. You can configure the pushbuttons
in three different ways: alternate, momentary, or alternate with PLC release
option. The associated LEDs, which can also operate totally independent of the
pushbutton action, can be triggered three ways: by the associated pushbutton,
by the PLC, or they can be made to flash by the pushbuttons. This screen also
allows the user to enter the associated PLC address. Once the address assignment
has been selected, all of the pushbutton and LED fields will be populated with
the associated bit assignments.
User Programmable Messages There are two message types which can be displayed: local and
PLC. Local messages are displayed on the screen unless the PLC
triggers a PLC message, which overrides a local message..
When a PLC message is triggered, the PLC Message LED will
also be illuminated. The PLC message LED will remain on until the user
acknowledges the situation by pressing [esc] on the panel.

Ethernet TCP/IP: All EZTextPLC models are available with built-in high speed
Ethernet TCP/IP communication interface in addition to RS232
and RS422/485 communication ports. This interface allows
EZTextPLC to reside on a 10 Mbps TCP/IP network (10Base
T Ethernet) via an RJ45 port. Use Ethernet models for easy
Ethernet programming with 100 meters being the maximum
distance between two nodes. For distances greater then 100
meters repeaters can be used to extend the distance between any
DeviceNet Slave Module: EZTextPLC models when ordered with built-in DeviceNet
Slave communication interface provide DeviceNet connectivity
in addition to RS232 and RS422/485 communication ports.
DeviceNet communication interface for EZTextPLC provides a
digital, multi-drop network that can be used for communicating
with DeviceNet enabled controllers and I/O devices. On
DeviceNet network every device acts as a node and allows
multiple communication hierarchies and prioritization of
messages. EZTextPLC with DeviceNet communication interface
can be configured in a master-slave control architecture as a
slave node and allows peer-peer communication. DeviceNet
control system provides a single point of connection both for
configuration and support for I/O as well as explicit messaging.
Profibus: All EZTextPLC models are available with built-in Profibus
Slave communication interface in addition to RS232 and
RS422/485 communication ports. This gives EZTextPLC
the ability to link with a Profibus Master Controller.
Profibus is a vendor independent open field bus protocol
standard in manufacturing automation and process control.
It reduces hard-wiring costs and provides specifications for
information exchanged between nodes of a Profibus network.
This communication interface provides the ability to transfer
data between a Profibus master and EZTextPLC.The Profibus
communication interface also has an auto-detect feature for the
baud rate of the Profibus network.
