1 Installation

1.1 Software

1. Download the GSD file from www.ifm.com => Article => [More information] => [Software
download] => Device master data (GSD) file
Example: RM3011 gsdml file

2. Extras => Administer GSD => Install GSDML

3. Additional Field Devices => Encoder, select ifm Encoder (see chapter 2)

Standard (optional): for controllers which support the IRT* function.

Standard, no PDEV: for controllers which do not support the IRT* function

*IRT = Isochronous Real Time (frequency rate <1ms; jitter accuracy 1µs)

2 Setting the encoder function:

2.1 Selection of the correct encoder:

Standard (optional): for controllers which support the IRT* function.

Singleturn: 8192 signals

Multiturn: 8192 signals x 4096 revolutions

Standard, no PDEV: for controllers which do not support the IRT* function

Singleturn: 8192 signals

Multiturn: 8192 signals x 4096 revolutions

For detailed information see operating instructions

 2.2 Multiturn encoder ifm Telegram 860 (standard):

Configuration (HW Config) => Properties Module Access Point => Parameter setting

Setting options:

Code sequence: Counterclockwise / clockwise

Class 4 functionality: Enable / disable

Scaling function control: Enable scaling / disable scaling

Measuring units per rev.: 8192 (factory setting)

Total measuring range: 33554432 (factory setting)

3 Setting of the measuring units (measuring range):

Simplified representation:

Measuring units per rev.

Standard: 8192

Revolutions
Standard: 4096

The resolution per revolution are the pulses which are provided for a revolution. The
revolutions are the further pulses for another entire revolution.

Example: 8192 x 2 revolutions = total: 16384

(1,2,…8192, 8193,…16383, 16384,1,2,…)

Input of the figures:

Maximum units:

8192 units x 4096 revolutions => total measuring range 33 554 432
The revolutions must never be more than 4096, therefore the number of total measuring units
is irrelevant.

Example:
7096 units x 2048 revolutions = 14 532 608 total measuring range => OK.
196 units x 4097 revolutions = 803 012 total measuring range => not OK.

Integers:

Only integer values may be entered.

Example:
8192 units x 2.5 revolutions = 20 480 total measuring range => not OK.

 3.1 Setting examples

The value for the resolution (pulses for a revolution) must be entered for measuring units per
revolution:

The total measuring range must be calculated.

Example.: 2000 pulses x 9 revolutions = 18 000

Standard: Scaling function disabled

Resolution per revolution 8192 x revolutions 4096 = total measuring range 33 554 432

100 units x 2 revolutions (total measuring range 200):

360 units x 1 revolution (total measuring range 360 singleturn):

 3.2 Setting examples with high and low word

For some controllers the value for the total measuring range must be converted to a high
word and a low word.

Standard setting 8192 units x 4096 revolutions:

 
 

8192 units x 4096 revolutions => total measuring range 33 554 432

total measuring range 33 554 432 in hex => 0200 0000 hex
high word 0200 hex in decimal => 512
low word 0000 hex in decimal => 0

200 units x 24 revolutions - enable scaling:

200 units x 24 revolutions => total measuring range 4800

total measuring range 4800 in hex => 0000 12C0 hex

high word 0000 hex in decimal => 0
low word 12C0 hex in decimal => 4800

200 units x 1 revolution - enable scaling:

200 units x 1 revolution => total measuring range 200

total measuring range 200 in hex => 0000 00C8 hex

high word 0000 hex in decimal => 0
low word 00C8 hex in decimal     => 200

4 List of variables, reset and preset

4.1 Display variables

Simatic Manager => CPU 315-2 (select) TAB  PLC => Monitor/control variable

Display measured value:

Operand ED 100 (for set input address 100...103), display format DEC, and monitor
variables.
Attention: When the properties are changed, a reset must be carried out to display
the current value.

706415_UK.doc 706415/00 Page 11 of15 © ifm

efector gmbh
 4.2 Reset:

Operand AD 100 (for set E address 100...103), display format HEX, enter 8 at the
first position in the control value (DW = Double Word) for a value change.
Only a change of the status value from 0 to 8 is detected; no value change is carried
out when the status value of 8 remains 8.
(Attention! Only to be carried out when the encoder is standing still)

Example reset:

OPERAND DISPLAY FORMAT STATUS VALUE CONTROL

VALUE
ED 100 Dec.. L#5120
AD 100 Hex.: DW#0000 0000 8000 0000

OPERAND DISPLAY FORMAT STATUS VALUE CONTROL

VALUE
ED 100 Dec.. L#0
AD 100 Hex.: DW#8000 0000 8000 0000

4.3 Preset:
Operand AD 100 (for set E address 100...103), display format HEX, enter 8 at the
first position in the control value (DW = Double Word) for a value change.
Only a change of the status value from 0 to 8 is detected; no value change is carried
out when the status value of 8 remains 8.
(Attention! Only to be carried out when the encoder is standing still)

Example Preset:

OPERAND DISPLAY FORMAT STATUS VALUE CONTROL

VALUE
ED 100 Dec.. L#0
AD 100 Hex.: DW#0000 0000 8000 0E10

OPERAND DISPLAY FORMAT STATUS VALUE CONTROL

VALUE
ED 100 Dec.. L#3600
AD 100 Hex.: DW#8000 0E10 8000 0E10

3600 (decimal) = 0E10 (hex)
