Preliminary Remarks

Notes for the reader

This documentation is intended for manufacturers of machine tools using SINUMERIK 840C. The publication explains the application of the complete Software Package 0, Basic Functions,

which the machine tool manufacturer can incorporate in his PLC program. The SINUMERIK documentation is organized in 4 levels:

• General documentation

• User documentation

• Manufacturer documentation

• Service documentation

The Manufacturer Documentation for the SINUMERIK 840C control is divided into the following parts:

•

Interface Description Part 1: Signals Part 2: Connection Conditions

• 135 WB/WB2/WD PLC Planning Guide

• Function Macros

• Function Blocks Paket 0: Basic Functions Paket 1/2: Tool Management Paket 4/5: Computer Link Paket 7: Code Carriers Paket 8: PLC Controlled Data Input/Output

In addition, there are SINUMERIK publications applying to all SINUMERIK controls (e.g. Measuring Cycles, Cycles Language CL 800).

Please contact your Siemens regional office for further details.

Notes:

1. To simplify programming, the interface signals from data blocks can be copied into flag area FY 25 - 99 using function macros FB 70, FB 71.

Function macros are function blocks programmed in Assembler and integrated in the PLC operating system.

2. Flag area FY 224 - 255 is saved by the basic program integrated in the system software on a level change and on a warm restart. The flag area is reloaded when the relevant program has ended.

This flag area can also be used to store intermediate results. Flag area FY 200 - 223 is used in part by function blocks (see FB Package Description). If

the user does not require these function blocks, these flags can be used in the same manner as those in flag area FY 25 - 199.

Caution:

Flag area FY 200 - 255 is also used in part by SIMATIC FBs. Flag area FY 200 - 255 is saved; this setting is performed via PLC MD.

Data formats: All word-oriented interface signals are input and output as fixed-point numbers. Exceptions

are expressly indicated.

Data blocks marked

are created contiguously according to the

tool management configuration.

DBs 150 to max. DB 182 are needed when tool management is used. The

actual number of data blocks depends on the "width" of the magazine

table (see documentation: SINUMERIK 840/840C/880/880 GA2, Function

Blocks for PLC 135 WB, Package 1 and 2: Tool Management).

Caution:

1. Make sure that no confusion with SINUMERIK blocks is possible. The user must not utilize a SINUMERIK standard block name, nor may he assign a SINUMERIK library number to his user blocks.

2. In the range of FB 0 - FB 199

FX 0 - FX 99 SINUMERIK blocks have absolute priority.

If SINUMERIK blocks must be used at a later time that overlap user block numbers, the user blocks must be given a new number.
