Ok, yes you will need to setup the communication parameters in the PLC and HMI. I do not have the software here so I cant really lead you through the configuration. You might check the mrplc forum. Someone there will probably be able to lead you through the setup. Just put as much info in...
learn controls engineering
The reality is that the best way to learn control engineering since you already have a degree is to look for a job in the controls industry. You can read all the books you want and take all the courses you want but the best way to learn controls is by doing. You...
how to learn plc
Vikram,
You can visit our PLCMentor.com site and it should help. There is a lot of free info there as well as tutorials and videos.

In the simplest sense, OPC is a tool that can enable software manufactuerers to connect to a variety of different field devices. SCADA and HMI systems today usually work in layers. You have a developer of a graphical system that allows people to monitor a process. The system may...
capacitor sensor principle
I would assume from the first line of the page that there is no difference. I quote:
"Capacitance level detectors are also referred to as radio frequency (RF) or admittance level sensors."

level admittance
There is usually just one probe. The circuit consists of a probe and is completed by the vessel wall. If the vessel is not conductive, then a conductive material must be inserted to complete the circuit. So in essence for most applications, the vessel could be thought of as...

I think you may do better to just go to the manufacturer or representative of a competetor. You can give them your model number and they should be able to match it with a comparable product if one is availabe. I would think that Allen Bradley or Siemens would make...
Sounds like and interesting training program. you would probably do better to see if you could get hired on by an automation company. You may not make as much in the beginning, but real world experience beats any training.
plc dcs forum
You have hit upon a discussion that has been raging in the industry for 20-30 years. Over the years, the two have come together to the point that there is not a whole lot of difference. The biggest difference is probably in their origins.
PLC's originated with discrete...
Hopper Filling system
Glad you worked it out. I was just trying to be helpful. Many times with forums people want to see that you have tried first. There are some places that asking for a program will generate lots of negative response. I think here it just resulted in noone responding...
gate valve
I think your problem here is that you wanted people to give you a program. Try posting a program you need help with or asking a specific question concerning a problem you are having programming this. However, we do work on a contract basis...
capacitive level sensor operations
You have to have a solid ground to get a reliable measurement with a cap proble. From your description it seems you have some drift. If possible I would suggest pulling a new ground connection from a known solid ground. It may be that you need to run a test...
You are going to have to post a little more info:
specifications of the devices you want to read from. Model number or cut sheet would be great
PLC type that you want to take signals into.
Someone should be able to help with that info.
