Support Questions / Re: HMI-PLC Compatability

« on: February 28, 2014, 02:43:54 AM »

Hi Archie

I have confirmed that the x-logic plc I was asking about in my other post Is in fact Modbus Rtu over Ethernet as apposed to modbus tcp. A concept I now understand, unfortunately after purchasing a plc I thought would work with your software, my bad. I'll put that down to school fees.

My question is, when the RTU driver is developed/released will there be an option for communication over Ethernet?

cheers,
Travis

Hi Archie

Thanks for the reply, I'm not so sure though. I don't think all the documentation has been properly updated since they released the Ethernet version. Take a look at the data sheet for the model I am am using: http://www.xlogic-plc.com/about_te.php?id=239.

The modbus read/write blocks also have the option of com type: Ethernet, and protocol: modbus tcp(rtu).

Support Questions / PLC addressing for 'dummies'.

« on: February 25, 2014, 04:23:30 AM »

Hi Guys

Can somebody point me in the right direction here. I am very new to this and researching as much as I can, but its a steep learning curve.

 I have written a  program which is fine, I have also written a basic program using Advanced HMI but am struggling to get any communication happening.
The PLC is an Xlogic which is very 'similar' to the Siemens Logo, it does support Modbus Tcp and I have tested this connection with PLC to PC(programming software) with success.

My main question is do I need to incorporate Modbus Read\Write function blocks into my programming wherever I need this communication to happen with HMI or can this simply be done directly with the Imput/Output blocks? If so what are thier addresses?

For example I have an automatic cycle but would like to switch to manual to operate my outputs via HMI. Lets say I need to operate Output 1 via basic button. I'm assuming I need to put the address of the output into PlcAddressClick to operate this output? This is where I'm struggling.

This is assuming that this is all possible with this PLC.

Heres a link to the Xlogic manual which has some information on the Modbus communication instructions: http://www.xlogic-plc.com/Modbus%20communication%20instructions.pdf 

Any help would be hugely appreciated.

Cheers,
Travis

Open Discussion / Re: Simulation driver

Thanks again Archie.
I was hoping there was a way to run HMI simulation and PLC simulation on the same machine, the PLC is on its way so I will just have to wait.

Cheers,

Hi guys

Another newbie question but can somebody please explain the use, intention of the simulation driver.

Support Questions / HMI-PLC Compatability

« on: November 17, 2013, 07:28:07 PM »

Hi Guys

I am both new to the forum and to hmi's in general. I am automating a brewing system and am very keen to use Advanced HMI. There are a few things I am unclear of.

Am I right in saying that currently there are only drivers for Modbus TCP which means both the PLC and HMI need to have an ethernet port?
Does this also mean that the HMI needs to support Modbus TCP?
This is probably a very dumb question but what is/are the operating systems of HMI's or are they software independant? Can you simply write the program and load the .exe onto the hmi?

Excuse my ignorance and thanks in advance, a lot of research has returned little clarity on these questions.
