Display Languages

If your PLC model is 'multilingual' you can type and display a number of languages on the controller's LCD. When you install U90 Ladder, the Display Settings box opens, enabling you to determine a default language for the HMI Displays. After installation, you can change the PLC Display Language at any time.

Modems

Modem Services, on the Controller menu, replaces PC Modem Configuration.
Modem Services enable you to initialize supported modems for both PC and PLC-side modems, via a 'Prepare Modem' procedure.

U90 Ladder V3.81

Document version: 22/ 06/ 04

PID Server:
Auto-tune PID loops

The PID Server PC utility enables you to auto-tune PID loops for both the Vision and M90/91 controller series. Although it is installed as part of the VisiLogic/U90 Setup, PID Server runs independently of other Unitronics software.
PID Server tunes a PID loop by temporarily disabling the PLC's PID function, and tuning the loop while the PC controls the PID output. The new utility is located on the Tools menu in both VisiLogic and U90Ladder

 

MODBUS
New M91 feature

MODBUS enables you to establish master-slave communications with any connected device that supports the MODBUS protocol, including SCADA systems. Any controller in the network may function as either master or slave using any of the controller's existing COM Ports. Unitronics currently supports RTU (binary) transmission mode.

PID Function
Last received

The PID function has been modified:
Negative Slope control has been added.
The Deadband parameter has been removed.
Please note that, in existing applications, the changes may require you to modify the P, I, and D parameters.

SMS number

New SIs, 188 to 192, now store the number of the last SMS received by the controller.
