0 NotesThis description deals with the following:

• the positioning module WF725A/B and WF726A/B/C• the operating panel WF780• the interface module WF785• screen and keyboard with WF470

and the STEP 5 standard software packages

– Standard I-726– Standard II-726– Standard III-726

The application of the WF module in the various SIMATIC S5 programmable logic controllers ishandled in this description.

The relevant WF725/726 documentation is listed in chapter 9.3.The standard software ”Overlay” (Schale) has been developed to simplify the use of theinterface.

It is not possible to mix software Standard 1 (Order number 6FM1725-

7A.00) with Standard II-726 or Standard III-726.

It is not possible to use the operating panel WS700G in conjunction with the WF726 module.For this, the WS780 operating panel should be used.

The disc for Standard III WF470 Masks :

A data transfer area must be generated in the system data list on the WF470 Standard masksdisc using the picture generation software. A DB , with any number, is used for the datatransfer area and its length must be at least 20 data words.

The WF470 transfers the status of the function keys into DW10 of the data transfer area. Forcorrect processing in flag words, the left and right data bytes must be exchanged. After thisdata word has been read out it should be set to zero by the user program.

• Text lists in the case of machine faults

There is enough vacant space in the diagnosis mask DIA to accommodate a further maskfor displaying machine faults.

• Cursor function

By pressing the cursor key, the cursor can be positioned in the text area or in the V-field(it functions like a flip-flop).




































The STEP 5-program is in german version in the program examples.

1 Overview

1.1 Structure of the software Standard I-726, II-726, III-726 withoutOverlay (Schale)

Standard STEP 5 software is available to simplify the programming of the WF725/WF726. Likethe hardware, the software is modular in form (see fig. 1.1).It is possible to mix WF725's and WF726's with the new software.

Standard I-726 is not on the diskettes for Standard II-726 and StandardIII-726. Standard I-726 must be ordered separately.



































It is not possible to mix software Standard 1 (Order number 6FM1725-

7A.00) with Standard II-726 or Standard III-726.

1.3 Specification of terminology

1.3.1 Main modes and submodes

The WF725/WF726 has the following main operating modes:

– Operating mode Traversing– Operating mode Programming– Operating mode Service– Operating mode Machine data

• These main modes apply to the entire WF module and to all axes on that module, i.e. theWF interface to the S5 is switched when the operating mode is changed. The selection ofthe main modes is described in chapter 2.

• When the main mode is changed the positions of the limit and pre-limit switches are readout of the EEPROM store.

• Only these four main modes are allowed with their respective identification codes. If anyother code is issued to the WF module, a fault message will be written into DBWF DW39.

The following submodes all come under the main operating mode Traversing and can beselected separately for each axis.

- Operating submode 1: Jog - Operating submode 2: Referencing - Operating submode 3: Manual data input (MDI) - Operating submode 4: Follow up - Operating submode 5: Velocity control - Operating submode 6: Axis clamped - Operating submode 7: Setting of actual value - Operating submode 8: Single block - Operating submode 9: Automatic cyclic - Operating submode 10: Automatic single step - Operating submode 11: Automatic buffer (only WF 726)


1.3.2 General definitions

In order to simplify this description the following system has been adopted:

To identify the axes, they have been given the letters A,B,C. On the machine, the axes mayhave numbers to identify them:

Axis 1 on the module = axis AAxis 2 on the module = axis BAxis 3 on the module = axis C

Resolution: This is the distance represented by one encoder (increment);1= 1 µm per increment2= 10 µm per increment3= 100 µm per increment

1.4 Basic principle of the data transfer

The data transfer with the WF725/WF726 is the same whether machine data, movementinstructions or other data are to be transferred. The user needs to select the interface DB andto write the data into the DB and finally to set the strobe. The actual transfer is done bystandard FB's. The user does not need to bother about the data handling in the dual port RAM(such as transfer reqest, acknowledgement etc.).
