[problems connecting to the PLC (JZ20) using the USB]

Hi,

What is a U90Ladder version?

What is your Windows OS and version?

You have to install driver first, then connect Jazz to PC by USB cable.

In Device Manager this driver should be listed as "STMicroelectronics Virtual COM Port (COMx).

When Driver Update dialog pop-ups - cancel update.

Where x (port number) should be between 1 to 16.

You have to select this port number in U90Ladder PC Communication Port Settings.

[XY graph possible with V570?]

Hi Garry,

Use Utils->HMI->Draw Line. It will draw you a line between 2 points.

You have to scale you date to display area and transform it to pairs of display coordinates. Then draw line between two pionts.

 

Draw Line use direct draw to PLC memory, so it will interfere with any display elements.

[V280 Factory Reset Issue]

Hi,

What are PLC system files versions (from Info mode)?

What VisiLogic version did you used?

 

Power-off PLC, keep I button pressed and power-on. PLC will start in OS Stop mode. Check communication.

 

Enter Info mode, enter System, scroll to select Erase. This will erase mostly all.

After erasing, PLC stay in Bootstrap mode.

You have to use COM 1 of PLC to communicate and download OS, and then application.

 

I hope this helps.

[Alarm Reset]

Hi,

You can protect by password Reset and Acknowledge operations.

Anybody can push external button and reset/acknowledge alarm.

The meaning of such design is to bring REAL operator attention, and sometime keep a record who did reset/acknowledge of alarm.

This is a requirement of standards for specific industries.

[Alarm Reset]

Hi,

Reset and Acknowledge bits are outputs, and changed to ‘1’ when corresponding buttons of Alarm screen pressed.

Alarms support is embedded into OS, and there is no access to Reset and Acknowledge button bits.

 

The meaning of such design is to bring operator attention and lead to action.

[Subtracting Totaliser]

Hi,

Ideal is to register filling and consumption. Level detectors will help against overflow.

As I see, you already have consumption meter. When you add filling meter - you will have 2 numbers - income and outcome.

Difference will be read at the end of day.

I hope this helps.

[PWM - IO-D16A3-TO16]

Hi,

In accordance to specification of IO-D16A3-TO16, max. PWM frequency is 32K.

MI is fitting this.

You stop PWM by writting 0 frequency.

*You should use slowest servo when connect to IO module.
