BECKHOFF / Send/receive string with UDP

« am: 21. April 2019, 15:47:29 »

Hi there,

I'm trying to send this string: '20 00 00 00 16 02 62 3A D5 ED A3 01 AE 08 2D 46 61 41 A7 F6 DC AF D3 E6 00 00 1E' of hexadecimal values over UDP to an IP address.
I should receive this answer: '28 00 00 00 11 00 02 98 D8 63 35 D2 EA F6 C3 DC 00 01 7B 02 00' for further analysis.

I think I could use the http demo example for this, however, I do not understand the url_text syntax for this.
Can you point me in the right direction?

BECKHOFF / Connection with Influxdb - cURL

« am: 12. Januar 2018, 20:12:16 »

Hello,

I'm trying to connect with Influxdb HTTP API.
The working cURL command on my debian system is: curl -i -XPOST 'http://localhost:8086/write?db=mydb' --data-binary 'cpu_load_short,host=server01,region=us-west value=0.64 1434055562000000000'

I've tried the same command in the http demo, but there is a http get 252.
What is the syntax for using cURL?
Thanks

Codesys 2 / Rasberry Pi DLOG_FILE_CSV_DEMO

« am: 09. März 2017, 16:09:28 »

Hi, I'm trying to get the DLOG_FILE_CSV_DEMO to work in codesys 3 on a raspberry PI.
If I compare the running program with a Beckhoff CX, i notice that the timestamp does not change on the PI.
Also the filename stays the same and the file is not written on the SD card. There are no errors.
- What is wrong with the timestamp in the real time view, it stays like '#A-#D-#H-#N:#R:#T'
- What is the format to write to the sd card of a raspberry Pi on linux?
