IC cards can be used as additional memories for PLCs that can use them. With the IC memory card manager you can format, write, read and clear IC cards under Control FPWIN Pro7.
IC card
Control FPWIN Pro7 supports IC cards for SRAM and F-EEPROM. Depending of the type of IC card inserted into the PLC, certain functions (e.g. formatting) are locked out in the IC memory card manager dialog.
Memory areas in the IC card
The memory of the IC card can be divided into two memory areas: Expansion memory area and memory formatted for MS-DOS. On a new IC card direct from the factory, the memory is allocated to the expansion memory area only. Memory formatted for MS-DOS can be achieved by formatting the IC card. Programs or data can only be stored in a memory that has been formatted for MS-DOS. Only binary data can be stored in the expansion memory area. Binary data stored in the expansion memory area can be stored or read by the PLC by using the instructions F12_ICRD and F13_ICWT.
Load the program from the IC card to the PLC’s programming memory when you turn on the PLC.
A program stored on the IC card with the data name AUTOEXEC.SPG (capitalized) is executed by the PLC when it is turned on if the dip switches on the PLC are configured accordingly.
The following functions can be performed:
Find file
Search files on the IC card. You may enter the file name or, if you are not sure of the file name, enter e.g. 'FRA??.NCB' in the field Name (wildcard asterisk (*) is impermissible). In the latter case, all files will be listed starting with FRA, one or two any letters and the extension .NCB. Click OK to start the search procedure.
Delete (only with SRAM IC cards)
Click on the file to be deleted in the list and Delete. Confirm this delete procedure.
Rename (only with SRAM IC cards)
Click on the file to be renamed in the list. The current file name is displayed in the field Name. Enter the new name and click Rename.
Properties
Click on the file with the attributes to be changed. You may enter a comment in the field Comm. In the field Author you may enter your name. By clicking on the field Read Only the file is write-protected.
Download >>
Please note that an F-EEPROM IC card has to be erased before data can be transferred. Click Erase.
| Disk Download >> MS-DOS | Several files on the hard drive can be saved on an IC card that has a memory formatted for MS-DOS. You can select several files by using the control or shift key. |
| Disk Download >> Expansion area | One file on the hard drive can be saved to an IC card’s expanded memory. |
| Project Download >>MS-DOS | The program currently being compiled can be saved on an IC card that has a memory formatted for MS-DOS. |
<< Upload
Please note that the PLC type with the selected *.SPG file has to correspond to the PLC type of the Control FPWIN Pro7 project. Otherwise an error message occurs.
| Disk << Upload MS-DOS | The file selected in the IC card’s Manager Dialog can be saved on the hard drive. Click [Find File] to select the file saved on the IC card. |
| Disk << Upload Expansion area | The binary data stored in the expanded memory of the IC card can be saved as a file on the hard disc. |
| Project << Upload MS-DOS | Selected *.SPG files in IC card manager dialog can be saved in the Program code editor in Control FPWIN Pro7. Click Find File to select the file saved on the IC card. |
Format... (only with SRAM IC cards)
The IC card can be formatted. Before, the format of the IC card and the size of the MS-DOS memory area have to be indicated under IC card Attributes.
Initial
Initializes the IC card and clears all data thereon. Then, a new DOS partition has to be installed and the IC card has to be formatted. After initialization, the memory of the IC card is allocated to the expanded memory. You must then format an SRAM IC card in order to reserve MS-DOS memory if this is necessary.
Please ensure the write protect switch of the PLC has to be in the Access enabled position (see hardware description) and the IC card is not write-protected during writing.
