[Data table editor error]

In Ladder, where you use STORE TO DATA TABLE, use OVERWRITE, not APPEND.

Review  example:

C:\Program Files (x86)\Unitronics\Unitronics VisiLogic_C\Examples\Version 900\Project examples\SD\V570_SD_card_demo.vlp

 

AAAHH!  i'm so stupid.

Thank you !

Message exactly explain situation.

UDT file with appended sections cannot be edited.

You have to use OVERWRITE option to be able to edit UDT file.

 

What do you mean OVERWRITE?  How to do it?

When i try  with Data tables editor which is part of  SD card  suite,  to edit or clear the cells get this error. Why ad how to solve this?

I have simple solution for your problem.

[I/O Expansion module]

JZ- EX 8Di -8Do

Dear UNITRONICS users.

 

This is my another device, which i developed, and  it's  used several times in my  projects. This expansion module looks like EX90-DI8-RO8 expansion module from Unitronics.

Our module also have 8  digital inputs which can be sink or source configurated, and 8 digital (transistor) outputs which can be also sink, source or even for AC voltage configurated  with  max. 0,5A current per output.

 

This module can be connected to any  OPLC from Unitronic series. The module communicating with PLC via RS485 port. In this case JAZZ series needs a RS232/RS485 Add-on port (JZ-RS24 )  Also PLC must have a short communicating software which is in attachment. It's wery short, occupies only 7 nets.

The second choice of this module is standalone mini PLC, because is based on Atmel AMEGA168 AVR with a 16k of programming space. It can be updated up to 128k programming space on request. If you have a skills of AVR programming, there is no problem to write your own software (AVR studio, Arduino, Bascom ) and upload him thru ISP port. The modules can be networked via RS485. Also is possible connect some device like HDD44780 based LCD diplay to ISP port!  The  power supply for module is  10V to 30VDC or AC, and power consumption is obout 3W.

 

Specification:

Board size (WxHxD):  90x77x60 mm - DIN32 module base

Digital inputs:  8 inputs in 1 group , pnp or npn (10- 30VDC,AC on request)

Digital outputs: 8 digital outputs in 1 group , pnp or npn , max. 0,5A per output – fused (10 -30VDC/ AC)

Response time (inputs/outputs):  approximately 30ms

Communication: RS485, 9600,8,1,N

Power supply: 10 – 30VDC/AC , 3W

[More inputs on JAZZ]

Dear UNITRONICS users.

 

Sometimes it happens that you need more digital inputs on the OPLC because of pushbuttons.

 A solution is an OPLC with a larger number of inputs or an extension needs to be added when is possible. That can be  expensive. I developed a simple solution, which I  named,  the pushbuttons to current loop converter.  In this case, you only need one analog input (4 – 20mA), to add up to 19 pushbuttons via  two-wire shielded cable which can be up to 100m long.

The converter is self powered ( powered from current loop ).

The converter is reliable, since a very stabilized reference circuit is used.

The error is maximum +/- 1 digit on 10bit AD

 

I attach software  for  JAZZ with examples for easier understanding. It can be also used with others OPLC.

 

The converter is only available in our company for now.
