With the key the selected function is confirmed. With the function the selection of the loader function is activated again.

5.2.1 Project transfer from a PC to the storage card

With this function a PLC program including AS-i projection is stored from the PC on the card using the software ecolog asi system. To do so, the serial PC interface (COM1 or COM2) must be connected to the interface "Program loading connector" of the addressing and program loading unit with a null modem cable.

To be able to transfer a program from the software ecolog asi system the user must first log into the addressing and program loading unit via the menu point "Online/Login" after selection of the loader function "PC=>Card" and pressing . After login the projections are compared. To do so, the projection must be loaded to the card by confirming the question

"The projections in PLC and PC are different! Which projection should be taken?"

with

"Download to PLC"

In this case the program loading unit serves as a "PLC". The program is then loaded on the card, i.e. the question

"No program on the controller! Download the new program?"

must be confirmed with

"Ja" (yes)

After loading the AS-i projection and the PLC program the communication with asisys is interrupted.

If the question

"No program on the controller! Download the new program?"

is confirmed with

"Nein" (no)

the eASi tool remains logged in. In the configuration window (selection via the menu point "Window/PLC Configuration") the submenu "Bin. Download" is then available under the menu point "Extras" to transfer a program from the hard disk or a diskette to the storage card.

If the loader function "PC=>Card" has been selected and confirmed by pressing

and a storage card is in its location, the device first checks whether the storage card is empty to avoid clearing the card inadvertently.

If it is not empty, the message "Card full" is indicated for approx. 3 s and then the loader function "Clear" (see section 5.2.4) is activated. If it is necessary, the inserted storage card can be cleared.

5.2.2 Project transfer from the storage card to the PC

With this function a PLC program including AS-i projection is loaded from the storage card to the PC and then stored using the software ecolog asi system. To do so, the serial interface of the PC (COM1 or COM2) must be connected to the interface "Program loading connector" of the addressing and program loading unit with a null modem cable.

To transfer a program from the storage card to the software ecolog asi system, the user must first log into the addressing and programming loading unit via the menu point "Online/Login" after selection of the loader function "Card=>PC" and pressing .

To do so, a "dummy program" must be created because otherwise logging into the controller is rejected with the message

"The project must be correct for login"

In the window "Messages" the following message is indicated:

"Error: Project must contain a POU named PLC\_PRG (main routine)"

To create the dummy program insert a POU type "program" named "PLC_PRG" via the menu point "Project/Add object". To ensure that this POU is accepted by the compiler of the ecolog asi system there must be at least one instruction. In IL this instruction can for example be "LD 0" or in FBD "TRUE".

After creation of the dummy program the user can connect to the program loading unit as usual via the menu point "Online/Login".

After login the projections are compared. To do so, the message

"The projections in PLC and PC are different! Which projection should be taken?"

must be confirmed with

"Download from PLC"

The following question

"No program on the controller! Download the new program?"

must be confirmed with

"Nein" (no)

to keep the program loading unit logged in. In the configuration window (selection via the menu point "Window/PLC configuration") the submenu "Bin Upload" is available under the menu point "Extras". The projection indicated in the ecolog asi system now corresponds to the current projection stored on the card.

If the loader function "Card=>PC" has been selected by pressing and a storage card is in its location, the device first checks whether a program is on the storage card. If there is no program, the message "Card empty" is shown for approx. 3 s and then the selection of the loader function "Function Loader" is activated.
