U90 Ladder

i4 Automation U90 Software for Unitronics

U90 Ladder is the first programming software for early Unitronics’ PLCs. This basic programming software can be used to program the M90/91 & Jazz series of PLC.
See a full overview in the video below.

The new Jazz™ offers the flexibility of ladder programming (48K Ladder code, virtual), on-board I/O configurations (some models with direct temperature inputs), communication options, such as GSM/SMS, remote access, and MODBUS (Master or Slave) networking. The latest Series 2 Jazz now includes USB programming options.

The Jazz™ HMI application enables you to design up to 60 text screens, using up to 64 HMI variables for the display of time, date, and real-time system data.  Jazz™ programming is as easy as it gets – build ladder logic control applications using click-and-drop elements and create your HMI application in the same simple environment.

You can use U90 Ladder and the associated software utilities to program, control, access and download data to and from the PLC remotely and directly.
