1 Introduction – The SINUMERIK 840C

and its Operation

The SINUMERIK 840C is a CNC (Computer Numerical Control), intended mainly for automation applications.

Generally, the CNC implements the following basic functions (in conjunction with a machine tool or such like):

S Automatic workpiece machining S Free programming of axes S Programming of technological functions such as feed, spindle speed,

etc.

S Controlling of the axes and spindles in conjunction with the drives and

the measuring systems

S Scanning and controlling input and output signals via the PLC

program

S Machine operation via the machine control panel S Storing user data in the CNC memory S Organizing data exchange with I/O devices.

The operator interface (monitor displays, keyboard) is the connecting element between operator action and the machine. This Operator’s Guide describes only functions which are within the standard scope of supply of Siemens. The machine manufacturer can also configure functions and monitor displays and he can connect his own keyboard.

Please read the machine manufacturer’s Operator’s Guide in these cases.

1 Introduction – The SINUMERIK 840C and its Operation

1.1 Switching on the control

Switching on of the control can be implemented in various ways by the machine manufacturer. Please refer to the machine manufacturer’s specifications.

Please note: The control is switched on by switching on the input voltage at the power

supply of the central controller. After the control has been switched on, different start-up images appear

for a few seconds. The control software is loaded, i.e. the NCK and the MMC software is booted from the hard disk.

When the control is installed, the PLC software is loaded from the hard disk into the battery-backed RAM memory, i.e. the PLC software is not booted when the control is powered up.

10.94

Power-up of the control is performed in the following sequence:

1. The operating system software is loaded

2. The user data are loaded from the NC/DATA directory on the hard disk. These might be IKA and GIA data. The machine data (TEA1, TEA2, etc.) are not loaded during power-up. These data are stored in battery-backed memory.

3. The system now loads all of the data assigned to the STANDARD workpiece. The Siemens and user cycles can only be loaded with the STANDARD workpiece (LOADCYC command in the job list). The machine manufacturer can configure whether the last selected workpieces are to be loaded from the hard disk at this stage. If, in the 3rd phase, the same data are loaded with a workpiece (e.g. RPA, TOA etc.) as in the 2nd phase, these data are overwritten by the workpiece-related data.

If not otherwise configured by the machine manufacturer, the main menu of the JOG mode appears after power-up of the control. Operator actions on the control can be performed after the screen has built up completely.

1.2 Structure of the operator interface

5 operating areas The SINUMERIK 840C operator interface is divided into 5 areas:

MACHINE, PARAMETER, PROGRAMMING, SERVICES and DIAGNOSIS. The 5 areas will be displayed as softkey functions any time you press the area switchover key.

Area switchover key

Machine Parameter Programm. Services Diagnosis

Fig. 1.1 shows you which operator actions are possible in the different operating areas. With the SINUMERIK 840C, you can edit the part programs in two different memories:

S in the NCK memory (volatile RAM memory) S on the hard disk (MMC–CPU).

If you work on the volatile RAM memory, you must store the edited or newly created programs on the hard disk if they are to be retained after switching off the control.

If you edit a program on the hard disk, this program must be loaded in the NCK memory in order to be executed.

For this purpose, the SAVE softkey function is provided in the MACHINE and PROGRAM areas as well as the SAVE NC function in the SERVICES area. The PROGRAM area optionally offers a graphic programming system and a DIN code simulation. You will find a description of this system in separate publications of the User’s Guide Graphic Programming System for

S Drilling/Boring and Milling S Turning

and in User’s Guide, Simulation: Milling and Turning.

1.3 Menu switchover

Softkeys are keys which are variably assigned with functions. The 5 areas of the SINUMERIK 840C are selected via softkeys. Within

these areas further branching via softkeys is possible. Operating the RECALL key brings you back to the next higher menu

level.

An arrow in the first softkey window indicates that you can return to a menu:

1.3 Menu switchover

In each area, the menu last active is stored on area switchover (exception: MACHINE area). If you leave an area and do not wish to return to the menu level currently selected, you switch over to the main menu of the area with RECALL. This brings you to the defined initial status of this area. This procedure simplifies operation when first selecting the area. By pressing the SHIFT and RECALL keys you will obtain the basic display immediately from any branch in the PARAMETER, SERVICES, DIAGNOSIS and PROGRAMMING areas.

When leaving the area the control “remembers” the deselected area. This area is selected again by pressing the area switchover key twice.

1.4 Directory structure

Directories Structures from the PC world have been integrated in the SINUMERIK

840C. The PROGRAMMING, SERVICES and DIAGNOSIS areas as well as program selection (DATA SELECTOR) contain directories. These directories are a file management aid for sorting and storing files. Directories can in turn contain subdirectories. Only one directory level is displayed on the screen at any one time.

File The softkey bar does not change when you “page” through the

directories. Softkey function and directory are not directly related. A file is a logical data unit which you can address with a name (e.g. MPF1, TOA1, ...). Files can be assigned to directories according to specific criteria, i.e. MPF1 to the workpiece (directory) SHAFT1 or TEA1 to the directory NC. You can assign directories to other directories, which you also address with a name (e.g. LOCAL directory).

Directory path This results in “directory paths” which you can page through as follows.

Using the vertical cursor keys, set the cursor on a directory and press the INPUT key. The next subdirectoy in this directory is opened. Continue doing this until you have reached the directory of the files. You recognize files by the entry in the LENGTH column. You reach the next higher level from a directory level by using the vertical cursor keys to position the cursor on the line with the double dot the directory and then acknowledge with INPUT. If you have reached the highest level, the double dot is replaced by a hyphen.

at the beginning of

Data selector

Hotkeys

...

If you change the area by means of key or softkey functions (e.g. change from SERVICES to DIAGNOSIS) from any directory, the directory level last selected is stored. When reselecting the area, this brings you back to the directory used previously. Switchover between areas can be performed at any time, e.g. to look at a parameter or machine data.

A program that interprets your keyboard entries (cursor, input) as a file or directory selection, displays it on the screen (bar) and passes it on to other programs (e.g. editor).

With 840C software version 5 and higher the data selector responds to hotkeys. The first object (directory/file) in the current directory that starts with the letter or number entered is found and selected.

Fig. 1.2 SIEMENS directory and user directory in the SERVICES/DATA

IN–OUT/DEVICES area

Siemens directory The Siemens directory includes all data which are relevant for the

control’s operating system. You cannot edit or read out data in the Siemens directory; you can merely copy this data into the user directory, where it can be handled in exactly the same way as user data.

User directory The user directory includes all user data. The fact that system data

copied into the user directory can be edited there makes it possible to modify the configuration files of the control. The data of the user branch (if available) are always used before any other for the system configuration on powering up of the control. These possibilities are only relevant in the start-up phase and are password-protected against unauthorized operation.

You will find a possibility to use this structure in the SERVICES/DATA IN–OUT/DEVICE SETTINGS.

Here you can copy a standard interface configuration from the Siemens directory into the user directory and modify it in accordance with your data save device.

1.6 Screen darkening

The SINUMERIK 840C includes a function by which the screen is darkened after an adjustable period of time.

The default value of this period is 2 hours, i.e. as a rule the screen darkens 2 hours after a key has last been activated; this value can be changed in the PC data basic settings in the DIAGNOSIS area. The display is activated once any key on the alphanumeric keyboard or on the machine control panel, is pressed. The first keystroke simply reactivates the screen and does not initiate its normal function. With the screen darkening function, only the monitor is switched off and all other functions remain active.

By pressing the SHIFT and ACTUAL POSITION IN LARGE CHARACTERS keys, you can darken the monitor yourself and reactivate the display by pressing any key on the alphanumeric keyboard.

Screen darkening can also be implemented by the machine manufacturer via the PLC program. In this case, the operator actions mentioned above do not apply. Refer to the machine manufacturer’s Operator’s Guide.

Caution!

All internal processes which generate screen outputs do not cancel screen darkening. This also applies to alarms and operational messages.

It is advisable, however, to perform a data dump of all relevant data on an external data device (programmer, PC, etc.) because the data will be lost irretrievably if the MMC–CPU (which incorporates the hard disk) develops a defect.

Archive list As a backup aid, the SINUMERIK 840C allows directories and files to be

archived in archive lists, i.e. you can store a list of all important files and directories under a name that you specify and output this complete to an external device (see Services section, “Creating archive lists”). The SINUMERIK 840C has various hardware interfaces which can be addressed by the software.

Output via The RS232C (V24)/20mA interface on the MMC–CPU enables you to RS232C/V24 output your user data from the hard disk in PC format or in punched tape

format (see Services section, “Data input-output”). The interface automatically changes over between RS232C (V24) and 20 mA mode, depending on the connected device and corresponding cable.

Constantly update the backup data so that you have the current data available externally should a fault occur.

Via the RS232C (V24) interface, you can also print out data directly with a printer (SERVICES/DATA IN–OUT/PRINT function).

The SINUMERIK FD–E2 diskette unit (option) can be used for backing up data.

Computer link Optionally you can implement a computer link with the

SINUMERIK 840C (only in the NCK area) by using link modules.

3.1.1 Operating states – Operating state changes on change of operating mode

At the present time, each operating mode has one of the following operating states:

Program reset The machine is in the reset state, e.g. after switching on or after end of

program (M30).

Program running (not in JOG mode)

A program has been started and program execution is running.

Program stop A program in execution has been interrupted. NC Stop A program in execution is interrupted. All state changes which occur

during NC Stop (drift of one axis in the follow-up mode or traversing an axis in another channel) are taken into consideration after NC Start.

Here, a program can be a main program, a subroutine, a cycle or a number of NC blocks (e.g. in MDA mode).

NC Start disable NC START is disabled in the relevant mode group in certain error states,

e.g. if machine data are incorrectly parameterized.

The NC Start disable only applies to a single mode group.

Example If, for example, channels 1 and 2 of mode group 1 are disabled for NC

Start and channel 3 belongs to mode group 2, it is still possible to process a program in channel 3 with NC START.

If the mode changes, the operating state can also change. The following table shows how the operating states change on change of the operating mode.

In JOG mode, “Approach reference point” may be selected by pressing the appropriate key.

Now press the direction keys on the machine control panel. In the case of the machine control panel for a milling machine select the axis first.

The control checks the selected direction for traversing before the start: If the wrong direction key has been pressed (e.g. + instead of –) the op-

eration is not accepted and no movement takes place. When the reference point has been approached, this is displayed on the

screen for the appropriate axis. The control is synchronized with the machine once the reference point

has been approached for all axes. Using the FEED HOLD key, you can stop the selected axis before the

reference point has been reached.

The position of the reference point and the traversing speed are set by the machine tool manufacturer by way of machine data.

3.1.4.4 Increment mode – selection

Operating sequence

Before traversing the axes using the direction keys, select the appropriate incremental weighting on the associated machine control panel.

This key (INC variable) is used for traversing an increment previously set:

10.94

INC variable

For setting the variable increment, activate this softkey and enter the value you require in the input field.

Press the INPUT key for entering the value in the “Incremental weighting for INC variable” window.

Use the direction keys to traverse the axes incrementally in JOG mode. In the case of milling machine controls, select the axis first.

You can reselect this function by pressing the active incremental weighting key; JOG mode is automatically effective.

Note The selected increment function is displayed in the mode field.

The direction keys can act in two different ways:

S Modal S Non-modal.

Modal means that the axis is always traversed by one increment (corresponding to the setting 1, 10, 100, 1000, 10000 mm) regardless of whether the key is pressed briefly or held down.

Non-modal means that the axis is traversed only as long as the key is held down and the set increment is reached. When the key is released, the traversing movement is stopped – even if the set increment has not yet been reached.

3–14

If the key is pressed again, the increment is traversed anew.

Whether the increment is traversed modally or non-modally is determined by machine data.

3.1.4.4.1 Indexed traversing

If this function is assigned to the axis to be moved and the direction key is pressed, the axis is moved as though it were a normal axis. After releasing the direction key, the axis moves to the next indexing position in the direction of traversing.

Using the “Indexed traversing” function, NC axes can be positioned at particular grid points.

0° 360.000°

3 Machine

3.1.4 JOG: Set-up mode

The machine manufacturer uses machine data to assign the “Indexed traversing” function to individual axes. The parameters required are also preset by machine data. Please also refer to the machine manufacturer’s operating guide.

Example of “Indexed traversing” with a rotary axis: Number of divisions: 7 Number of divisions per absolute dimension Absolute dimension: 360.000° corresponds to the path to which the

number of divisions refers.

3.1.4.4.2 Indexed traversing with incremental dimension (INC)

If the “Indexed traversing” function is assigned to the axis to be moved and one of the direction keys is pressed, the axis traverses by one division increment.

It is irrelevant which INC function (1, 10, 100, 1000 or 10000) is selected.

A rotary axis can be traversed by one division increment only by pressing the INC 1 or INC variable key and entering “1”. The INC10, INC100, INC1000 and INC10000 keys have no effect.

The “Settable zero offset” selection is used to calculate the axis position for SAVE POSITION and GENERATE BLOCK. The zero offset (G53, G54, etc.) is not saved in the part program. The axis positions, which are displaced by the zero offset value, are entered directly in the generated block. Before the block is generated, you should check which zero offset is to be used in the part program. For the axes, you can choose between the settings “Traversed” and “Selected”. “Traversed” means that a block is generated with the axis positions defined in the “Axis selection” screen which have been traversed since the last block generation. “Selected” means that the block is generated with all of the axes defined in the “Axis selection” screen, regardless of whether the axes have been traversed or not.

The axis position change in the “Traversed” axes setting is effective

3.1.5.7 Block by block teach-in

Preconditions “Block by block teach-in” only functions in the NC stop state. If a new

part program is opened, for example, you must first start it using NC start. Only then can you switch to block by block teach in otherwise the message “Editing error, no permission to edit” is output.

In “Block by block teach-in” you can start the program and only modify or extend it at breakpoints. The advance decoding is switched off at the breakpoint.

You can advance to a breakpoint by:

S RESET (program start) S Traversing until stop at target block (BRK) S Decode single block (DSB) S Program step (PST) S Block search with calculation and subsequent processing of at least

one block in decode single block mode.

S Program end without M02/M30/M17 (TEACH IN and MDA programs

stop even without end of program character).

Teach in is only possible at program breakpoints that do not require advanced decoding (no tool radius compensation, no contour definition), otherwise editing is not permitted and the handwheel is not enabled.

G68 must always be programmed for block by block teach-in of rotary axes. Otherwise, the rotary axis might sporadically turn a whole revolution.

The following modifications are possible at the breakpoint:

S Delete following block S Edit following block S Insert new block before following block S Save axis positions in following block or insertion block S Generate insertion block with axis positions (see description and

examples for edit mode)

Note You can interrupt program execution even within a subroutine.

However TEACH IN is only possible in the main program level. The axis positions can be approached using the travel keys or the

handwheel if JOG/handwheel has been enabled.

3.1.5 TEACH IN mode

Every teach block that you generate or insert should be confirmed with NC start. Only then can you generate a new block.

Note To avoid collisions caused by operator errors, the following operating

rules are built into the system:

1. If the travel key or handwheel is used to move the position away from that of the breakpoint block, the new axis position must either be accepted or the position should be returned to the block start position. Otherwise the NC start is interlocked. The block start position can be reached using the REPOS function. You will find a description of the operator actions for the REPOS function in the section “JOG mode”. If, after REPOS, the function SAVE POSITION or GENERATE BLOCK is activated and “Traversed axes” was selected, the repositioned axis is not saved in the part program. If further axes are to be traversed after REPOS, REPOS should be deselected first.

10.94

03.95

2. If the axis positions in the teach block have been accepted, the travel keys and the handwheel remain disabled until the block has been processed with NC start.

The following general rule applies: You can abort the teach run at any time by:

S RESET or S Operating mode change

You will find a description of the functions overstore and block search in the sections of the same name.

REPOS in Teach-In If the search is started in the teach-in mode and the program is to be

subsequently processed in “Teach block by block”, the DSB must be enabled before the search is performed. This is the only way of ensuring that processing and decoding of the selected part program are correctly coordinated. If DSB is not enabled, you can neither edit nor reposition with the Repos offsets.

He notices that he has interrupted the program one block too soon. He does not want to save the position, but to run the program until position B. But NC Start is interlocked because of the movement away from position A. In step 3 he must first move the position back to A. He can then execute the missing block to position B in step 4.
