Unitronics Programming software
There are two programming packages for Unitronics integrated PLC & HMI's,
U90 Ladder which is for programming the Jazz and M90/M91 PLC's and
Visilogics which is for programming the Vision
series of combined PLC & HMI. Both of these packages are free of charge and
may be downloaded from the Unitronics website.
To allow third party software to communicate with a Unitronics PLC there is a free
of charge OPC Server which only requires that the
third party software can act as an OPC client. For the more ambitious programmer
there are a set of .Net controls that can be used, as well as an ActiveX COM
object, while for legacy systems there is a DDE Server . Finally Unitronics
PLC & HMI's also have their own communication protocol called PCOM which
can also be used. All of this software is free of charge and may be downloaded
from the Unitronics website.
Remote access software
There are two software packages that be used to remotely access Unitronics combined
PLC & HMI's Remote Operator which can monitor
several units at one time and Remote Access which will only monitor one unit
at a time. Both of these packages allow the HMI screens to be displayed on
a PC and allow the mouse to control the PLC. All of this software is free
of charge and may be downloaded from the Unitronics website.
In order to make the programmer's life a little easier Unitronics have developed
a variety of different tools that perform specific functions. One of the most
interesting but simplest is a licencing tool that embeds a licence number
into a hidden area of the PLC allowing the programmer to protect intellectual property
rights. There are also tools for data export and a small suite of programs
to manage the onboard SD card files.
These software programs and tools are constantly being perfected and upgraded and
the latest version can found on the Unitronics website ready for download, and YES!
you guessed it, they are free of charge!
