General Mach Discussion / Decimals when sending DRO's via MODBUS

« on: July 16, 2012, 06:31:22 AM »

Good afternoon,

I am sending the X-axis reading from Mach3 via MODBUS, but I am only receiving the integer part of the value.

For example, my x-axis position on Mach3 will be displayed as '+108.2145', but on my SCADA controller it is only displayed as '+108' without the decimals.

How can I overcome this problem so that the decimals will also be displayed?

I have tried using 2 registers in Mach3 when sending (i.e 32bits), but this still did not solve the problem.

Thank you for the assistance.

Kind regards

General Mach Discussion / Mach3 OPC server for SCADA application

« on: April 03, 2012, 06:06:45 PM »

Good evening,

Does anyone know which OPC server I can use to connect to Mach3?

I tried to connect Mach3 to my SCADA solution through the Modbus Serial RTU (Connecting 2 PC's with a null modem) and Mach Brains, but was unsuccessful.
I am using Movicon11.3 software to create the SCADA solution.

Thank you in advance for the assistance.

Regards,
Tremaine

VB and the development of wizards / Monitor Mach3 and transmit over LAN - VB HELP PLEASE!

« on: February 21, 2012, 03:24:32 PM »

Good evening,

I want to to able to monitor, through a network, when the mach3 software starts and stops its operation. I also want to be able to extract data such as motor speeds and positions to send to the SCADA software on the master station.
I have been looking at the VB script editor and macro's, but I can only seem to extract data when calling from g-code program. The problem is that the data will only be monitored when I call the macro.

Is there any way that I can continuously monitor the status of the mach3 software and transmit it to SCADA software over a local network?

Regards

Third party software and hardware support forums. / Monitor Start/Stop of Mach3 Software using external computer

« on: February 13, 2012, 05:40:02 AM »

Good afternoon,

My project is to create a base station (PC) using SCADA (Supervisory Control and Data Acquisition). A GUI (Graphical User Interface) on the base station must be able to communicate with a Reconfigurable Machining Centre (RMC). The RMC uses Mach3 software to perform machining. In other words, I want to click a button on a computer that is far away from the Mach3 system and be able to start the process on the Mach3 software and monitor its progress.

I am using Indusoft Web Studio to create the GUI on the base station and I will probably use the Modbus TCP/IP protocol, since it is desired to control the system from anywhere within our orginization.

Any ideas on how I can achieve this? Preferably without having to drive a pin high/low in the Mach3 program (G-Codes).

Thank you for your assistance.
