Machine Data Collection - NGC

Machine Data Collection - NGC

Introduction

This procedure will show you different ways you can collect machine data from a NGC Control.

MT Connect

The transfer of information between an MTConnect Agent and a client software application is  based on a Request/Response information exchange approach.

 A client software application  requests specific information from an MTConnect Agent. 

An MTConnect Agent responds to the  Request by publishing a Response Document.  

In normal operation, there are three types of MTConnect Requests that can be issued by a client software application that will result in different Responses by an MTConnect Agent.

Note: To get the best funcionality of the Haas MT Connect we recommend software version 100.20.000.1200 or higher.

MT Connect - Request/Response

The transfer of information between an MTConnect Agent and the user is based on a Request/Response information exchange approach.

In normal operation, there are three types of MTConnect Requests that can be issued by a client software application that will result in different Responses by an MTConnect Agent. These Requests are:

  1. Probe Request–A client software application requests the Equipment Metadata for each piece of equipment that MAY publish information through an MTConnect Agent.

    The Agent publishes a MTConnectDevices Response Document that contains the requested information.

  2. Current Request –A client software application requests the current value for each of the data types that have been published from a piece(s) of equipment to an MTConnect  Agent.

    The Agent publishes a MTConnectStreams Response Document that contains the  requested information.

  3. Sample Request –A client software application requests a series of data values from the  buffer in an MTConnect Agent by specifying a range of sequence numbers representing that data.

    The Agent publishes a MTConnectStreams Response Document that contains the requested information.

 

MT Connect HTTP Request Format

MTConnect follows the rules of HTTP to fetch and transmit the requested MTConnect command:

  1. Haas machine IP address.
  2. 8082 fixed TCP port.
  3. Model of the machine (i.e "UMC-750" or "VF-2SSYT")
  4. MT Connect agent request type: Probe, Current, Sample

MT Connect Request - Examples

http://172.21.16.31:8082/UMC/probe

http://172.21.16.31:8082/UMC/current

http://172.21.16.31:8082/UMC/sample

MDC - Ethernet Q Commands

Machine Data Collection (MDC) lets you use Q and E commands to extract data from the control through the Ethernet port or the Wireless Networking option. Setting 143 both enables the feature and specifies the data port that the control uses to communicate.

The Haas control uses a TCP server to communicate over networks. On the remote computer, you can use any terminal program that supports TCP; this example uses PuTTY.

Note: The Putty program can handle up to (2) simultaneous connections. Output requested by one connection is sent to all connections.

Note: To use MDC in this example the machine must already be connected to the network.

1

Make sure the machine is connected to the network. 

2

Set Setting 143 Machine Data Collect port to 5051.

Note: Do not use ports 8082 and 9090 - 9999 because they are already used by the Haas CNC control for other purposes. Check with your system adminstrator to make sure the port you want to used is not being use by another device in the network.

3

Go to Settings/Network tab and write down the IP Address of the machine.

Note: Make sure the Status is showing UP, if it shows DOWN the connection is not active, make sure the networking option is working correctly.

4

In the Host Name (or IP address) field. Set the machine's IP Address [1].

5

In the Port field. Set the Port number you specified in Setting 143, for this example it will be 5051 [2].

6

Set the Connection type to Telnet [3].

7

Click on Connection and check the box for Enable TCP keepalives (SO_KEEPALIVE option).

8

In Save Sessions type in Machine Data Collect. This will save the settings, next time you open the PuTTY program.

9

  1. Run the PuTTY program. Click on the Session Category.

10

Select Open to start the connection.

11

Turn the Caps Lock on your keybord.

12

Type ?Q100 .

Important: The letters must be uppercase. If the connection is active, the machine control responds with SERIAL NUMBER, XXXXXX, where XXXXXX is the machine’s actual serial number. For the initial connection, ?Q100 may have to be entered twice.

13

Refer to the next section for more Queries and Commands.

Query Format

The correct query format is ?Q###, where ### is the query number, terminated with a new line.

Response Format

Responses from the control begin with > and end with /r/n. Successful queries return the name of the query, then the requested information, separated by commas. For example, a query of ?Q102 returns MODEL, XXX, where XXX is the machine model. The comma lets you treat the output as comma-separated variable (CSV) data.

An unrecognized command returns a question mark followed by the unrecognized command; for example, ?Q105 returns ?, ?Q105.

Data Collection Queries and Commands Table

?Q402 M30 Parts Counter #1 (resettable at control) M30 #1, 380
?Q403 M30 Parts Counter #2 (resettable at control) M30 #2, 380
?Q500 Three-in-one (PROGRAM, Oxxxxx, STATUS, PARTS, xxxxx PROGRAM, MDI, IDLE, PARTS, 380
?Q600 Read a Macro or system variable MACRO, 0.0
?Exxxx yyyyy.yyyyy Write to Macro or system variable. See E Commands section

Q600 Command (Read Variable)

You can request the contents of any macro or system variable with the ?Q600 command; for example, ?Q600 xxxx. This shows the contents of macro variable xxxx on the remote computer.

E Command (Write to Variable)

You can use an E command to write to macro variables #1-33 and #10000-#10999.

Note: Macro variables #10550-#10580 are unavailable if the mill has a probing system. See the Operator's Manual for a list of available system variables.

The correct E Command format is ?Exxxx yyyyyy.yyyyyy where xxxx is the macro variable and yyyyyy.yyyyyy is the new value.

Note: When you write to a global variable, make sure that no other programs on the machine use that variable.

Caution: Use extreme caution when you write to a system variable. Incorrect values for a system variable can cause damage to the machine.

MDC - 8M Option Status Relays

The NGC control has the ability to communicate the status of the control using the 8M PCB relays.   The status of 8M PCB relays (outputs 90 - 97 ) will change state depending on the condition of the machine. 

 Note: To monitor the Power On or E-stop state an extra contactor will need to be added to the Power On and Emergency Stop button.

To use this feature you will need  to have a 8M option installed and a service key. 

 Note: If the machine is equipped with a non-servo autodoor option it will have the 8M PCB installed you cannot use this 8M PCB. In this case you need to install a secondary 8M PCB, refer to 8M Option - Installation.

To enable the feature go into service mode and change Factory Setting: 

  • 315.26 [315:26] STATUS RELAYS = TRUE

To see the outputs of the 8M PCB status relays on the control:

Press the [DIAGNOSTIC] button.

Go to the I/O tab.

Type in: 8M and press the [F1] button.
