How to connect PC & PLC with ASCII interface? I only started to work and I need some help (lessons).
How can I connect a PLC with a PLC with ASCII interface? What programs do I need? Please, any help, advice, suggestions?

Thanx.

 

What type of PLC?

 

Twido by Schneider Electric, Model TWD40...

 

Hi,

Your Twido PLC has a prgramming port. You can configure that port for remote link or Modbus RTU or Modbus ASCII.

 

If you configure the Twido port for Modbus, Automated Solutions offers several solutions for communications between a PC and Modbus device.

Fully functioning 30-day trial versions of all Modbus solutions are available for download.

 

1. You will need TwidoSuite, free from Schneider website.

2. You will need a connection to the Twido. It can be RS232, RS485, or Ethernet

The pinout can be found at the Pinout Project.

If you need a RS485 adapter, a cheap one can be found at

Whew!

Good luck.

 

Thanx everybody!

I'd done it. But I found another problem. I'm trying to send data from anolog input to PC, but Twido has 16bit number and ASCII is 8bit data...
