Serial communication in Labview/Hyperterminal
« on: June 10, 2002, 11:43:50 AM »
Hi all,

I wanted to communicate serially with the PLC using LabVIEW but was unable to do so. I also tried sending commands in Hyperterminal but the PLC did not respond (i.e. i typed IR* and nothing followed...) but when i do it in TLserver it works. Can anyone help me out seeing that i am fairly new to PLCs. Thank you.

To use HyperTerminal to talk to the PLC, you have to enter the multi-point version of the command:

@01IR00*

and you should get a response. The point to point version require the HyperTerminal to send a "Ctrl-E" character before sending the string "IR*".
