Re: My first real project.

it may sound complicated to you but in fact it is not. you need to spend some time on learning + practice and once you do the project you will realize it is simple. have a quick read about Django framerwork, Bottle framerwork, Django RSS feeds, RPi Webserver setup don't be scared and don't try to ge...

Re: rpi to detect subnet & obtain static IP & enable wifi

I own a network with ~ 20 subnets and all devices in each subnet have static addresses. I want to be able to plug in rpi to any subnet above obtain an ip address as mentioned in my 1st post but the address obtained is within a limit e.g. 4th octet is from the range 200-254 once ip obtained i want to...

rpi to detect subnet & obtain static IP & enable wifi

hi, I would like to do as follows: step1: plug rpi via eth cable to a managed switch with an ip address e.g. 192.168.xxx.2 NOTE: at this point in time we do not know what number is xxx step2: rpi to scan xxx range from 1 to 254 and detect ip address of the switch e.g. 192.168.10.2 ping successfull s...

Re: rpi + real-time data + live chart & other

hi, thanks for your reply. I want to stick to Python only because this is what I need to use to link rpi via Ethernet to device A. I do not have any other way of reading device A. rpi is located < 90 m away from device A and displays all the dashboards and counter on rpi touchscreen. 'real-time' mea...

Re: rpi + real-time data + live chart & other

Would it make sense to try to make a web app that display real time chart with e.g. 500ms update and real time countdown timer once certain event triggered? if let's say device A controller reads button ON or OFF and sends the status of the button via ethernet to raspberry pi that runs a web app whu...

rpi + real-time data + live chart & other

Hi, What is the best approach to solve such problem: I have a device that sets an output and I read this device output with raspberry pi via Ethernet. I read that device output every 250ms and it reads a string. If the string reaches certain value then I run some functions e.g. countdown timer and l...

Re: Turn Raspberry Pi into a P.L.C (Programable Logic Contro

How do you want to work-out safety aspects with you OpenPLC ? I guess SafetyPLC may be something that may stop you with your project progressing further or maybe you have already overcome this problem somehow ?

Re: Turn Raspberry Pi into a P.L.C (Programable Logic Contro

Here is Python code loaded by A.Ruscito to github that let's you access RA PLC.
You could use it for rpi to read/write to AB PLC via Ethernet/IP

rpi + python + timer display + data trending

hi, I have a device connected via tcp/ip with rpi. device can have one of ten states numbered 1 to 10. device constantly runs and loops through its states in ascending order starting from 1 ending with 10 and starts again 1,2, 3, ..., 10. it takes random time for a device to change its states and it...
