a Cimrex 30 as an operator interface. The Cimrex application is called M4PT_C30.

MMC_STEP. This example shows how to apply the stepper block I/O module. It contains the logic required to initialize the stepper block and to control it. A single UDFB (U_STPRC) provides the control logic for a stepper axis. The features supported by the UDFB include home (zero reference), jog, move a distance, move to a position, control-stop, emergency-stop and c-stop/e-stop reset.

MMC_DND. This example shows how to apply the Centurion DeviceNet Positioning MicroDSM drive. It contains the logic required to initialize and run the DeviceNet network. Two UDFBs provides the control logic for a DeviceNet axis to jog, move a distance or move to a position. A third UDFB provides the DeviceNet scanner status details. This example ladder and DeviceNet configuration are both referenced in the MicroDSM with DeviceNet installation manual.

The following is a brief description of each MMC for PC example (or starter ladder).

MPC4_EX. This example can be used as a starting point for a 4 axis application. It contains the logic required to initialize the servo axes, close the servo loops, jog an axis, and home an axis. It also contains basic E-Stop and C-Stop logic. This example does not have any operator interface support. All of the machine functions are performed with discrete I/O. This example is almost identical to MMC4_EX.

MPC4_OI. This example can be used as a starting point for a 4 axis application. It contains the logic required to initialize the servo axes, close the servo loops, jog an axis, and home an axis. It also contains basic E-Stop and C-Stop logic. This example uses a Cimrex C30 with an Ethernet module as an operator interface. The Cimrex application is called MPC4_C30. This example is almost identical to MMC4_OI.

MPC4_SOI. This example can be used as a starting point for a SERCOS application having an operator interface device. It contains the logic required to initialize the SERCOS configuration, initialize the servo axes, close the servo loops, jog an axis, and home an axis. It also contains basic E-Stop and C-Stop logic. This example uses a Cimrex C30 with an Ethernet module as an operator interface. The Cimrex application is called MPC4_SC30. This example is almost identical to MMC4_SOI.

Note: for both of the MMC for PC with Cimrex examples, there will usually be a configuration change required before either works. The Cimrex configuration file calls out the Ethernet connection to the MMC for PC. However, the correct TCP/IP address of the PC hosting the MMC for PC is unknown. The actual host address must be verified in the Cimrex configuration before it is downloaded to the Cimrex unit.

The ASFB folder contains the Motion, General and Ethernet ASFBs.

STARTING A NEW MMC APPLICATION FROM AN MMC EXAMPLE

The following is a description of how to start a new application from a standalone MMC example.

To use one of the examples as a starting point for your application follow the steps below. The following procedure will use the MMC4_EX Professional Edition Project as the starting point. The target application will be called NEW_APPL and the servo setup library will be ZNEWAPPL; other appropriate names can replace these used in this procedure. The same steps can be followed with the PiCPro Standalone MMC Edition.

1.

Start PiCPro for Windows V13.0 Professional Edition.

2.

File | Open, MMC4_EX Pro Edition.PRJ. This will open up the project.

3.

Once the project is open, do a File | Save As and fill in the following fields:

Destination PRJ C:\Program Files\Giddings & Lewis\Applications V13.0.1\New_Appl\New_Appl.prj This will be the name and folder for the new project.

Destination G&L C:\Program Files\Giddings & Lewis\Applications V13.0.1\New_Appl\New_Appl.G&L. This is the file name of the compressed project. The compressed file can be stored on the MMC Flashdisk. This allows the end user the ability to open the project from the MMC without having the original source code.

4.

Change the destination folders for Main LDO, Lib Path, UDFB Source, Servo Source, and Servo Lib's from: C:\Program Files\Giddings & Lewis\Applications V13.0.1\Examples To C:\Program Files\Giddings & Lewis\Applications V13.0.1\New_Appl

5.

Close the Save As Project by clicking OK.

6.

Expand the Main .LDO and double click on MMC4_EX.LDO. This will open the main ladder and do a File | Save As with the new file name NEW_APPL.ldo.
