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.

Technical Comments

The diskette for package 0 contains package versions 16, 20, 21 and 22. Depending on the SINUMERIK 840C software version being used, one of the following package 0 versions must be used.

Basic signals

e.g. auxiliary flags or dynamically assignable by interface signals

e.g. interface Channel 1 Channel 2 etc.

User assignable

Reserved for function blocks (see note)

Area saved on change of level and warm restart

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.

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.

1. Description

The ºMultiplier:16º function block can be used to multiply two fixed-point binary numbers (15+1 bits).

The result is a fixed-point binary number (31 + 1 bits).

The function block also scans the result for ºzeroº.

If 8-bit numbers are to be multiplied, they must be transferred to 16-bit words.

Function:	Y = A x B

FB 33 DIV:32

Divider:32

1. Description

The ºDivider:32º function block divides two fixed-point binary numbers (31+1 bits). The result (quotient and remainder) is a fixed-point binary number (31 + 1 bits).

The function block also scans the result for ºzeroº.

Function:	A
Y =	±±±±
	B

Y = Z32, Z31; remainder = Z42, Z41

A = Z12, Z11; B = Z22, Z21

FB 36 ADD:32

Adder:32 bits

1. Description

The ºAdder:32º function block adds two fixed-point binary numbers (31+1 bits). The result is a fixed-point binary number (31 + 1 bit).

The function block additionally contains a scan of the result for "zero".

If 8-bit numbers are to be added, they must be transferred to 16-bit words.

Function:	Y = A + B
	Y = Z32, Z31; A = Z12, Z11; B = Z22, Z21
