Display and Control Keys
2.1
General
The position indicator has a two-line display with special characters and three control keys.
The keys serve for position indicator parameterization and control. One LED (1) serves for
position monitoring.

Display and Control Keys
2.2
LCD display
The display range is limited to -19999 … 99999. Values outside this range
are displayed with "".
With supply voltage applied to the position indicator, the 1st line shows the actual position
and the 2nd line shows the set point with factory settings. The values displayed are
determined by the operating mode.
Direction indicators (arrows) support positioning.
The battery symbol
is shown with a critical or insufficient battery status.
With incremental measurement function activated, the incremental measurement symbol
is shown.
2.2.1
Extended display range
If values below -99999 are to be displayed, this can be realized by means of the control word,
Bit3 in the operational mode with SIKONETZ5 protocol. If this bit is set and the value to be
displayed is in the range between -19999 … -99999, then the negative sign and the figure
with the highest value are blinking alternately. If the value range drops below -99999,
"" will be displayed.

Pressing the
key enables or disables the incremental measurement function.
Pressing the
key starts calibration (see chapter 7.2 Calibration) and acknowledges a
pending error (see chapter 6.2 Errors).
Pressing the
key starts the parameterization mode (see chapter 3.4 Parameterization of
the position indicator).

Position monitoring
(see chapter 3.3 Loop positioning)
Arrows: (see chapter 4 Parameter description  Parameter no. 17)
Arrows are displayed to support the user with positioning as long as the current actual
position value is outside (see chapter 4 Parameter description  Parameter no. 26) target
window1. The arrow indicates the direction the sensor must be moved in order to reach the
target value.
LED display: (see e. g. chapter 4 Parameter description  Parameter no. 11)
With factory setting, the LED glows green as long as the actual position is within the
programmed window. When leaving target window1, the LED glows red.
An additional target window (target window2) and an associated visualization can also be
configured (see chapter 4 Parameter description  Parameter no. 27, 28 and 29).
System status word and SIKONETZ5 status word (see chapter 4 Parameter description 
Parameter no. 33):
In the system status word, the dynamic and static target-window-reached bit is set upon
reaching target window1 The dynamic bit is deleted when leaving target window1. The user
must acknowledge the static bit.

Loop positioning
The LED display refers always to the actual set point, not to the loop value.
Target window1 is also applied to the loop length.
If the position indicator is operated on a spindle or an additional gear, the spindle or external
gear backlash can be compensated by means of loop positioning. In this case, travelling to
the target value is always from the same direction. This direction of approach can be defined.
Example:
The direction from which every target position shall be driven to is positive.
 Case 1  new position is greater than actual position:
Direct travel to the target position.

Case 2  new position is smaller than actual position:
The position indicator's arrows show that the set point is to be overrun by the loop length.
Afterwards, the set point is approached in positive direction.

Parameterization of the position indicator
The position indicator can be completely parameterized via the keys as well as via the bus
interface.
3.4.1
Manual parameterization
3.4.1.1
Starting parameterization
After applying supply voltage, the position indicator will be on the uppermost level of the
menu structure (default/delivery state).
By actuating the
key, the set node address and baud rate is displayed. Parameterization
starts after expiry of the release time (see chapter 4 Parameter description Parameter no. 9).
3.4.1.2
Value input
With value input via the keys, the display range is limited to -19999 …
99999. When entering values beyond this range via SIKONETZ5 or the
service protocol, "" will be displayed when you call up the parameter.
Enter values via the
key and the
key. Confirm values entered by pressing the
key.
- decimal place selection key
- Value input key
3.4.1.3
Value selection
For some parameters you can select values from a list.
Direct value input is not possible there.
Pressing the
key, the value can be selected from the list. By pressing the

Offset value:
Changes to the offset value are
considered in the calculation of
the position value immediately
after value entry / transmission.
The following equation is applied
in case of calibration:
Position value = 0 + calibration
value + offset value
Calibration value:
Changes to the calibration value
are adopted for calculation of the
position value (via
key or S
command) only after calibration).
Then one has:
Position value = 0 + calibration
value + offset value
Positioning window1:
The target position has been
reached when the indicator's actual

Resolution with free factor
On principle AP04S supports the resolution steps indicated with Parameter no. 24. If
resolutions different from these increments are required, or if AP04S e. g. is used for instance
in a rotative measuring system (not GS04), then a (free) factor must be set.
Internally, the display functions with a resolution of 0.01 mm. Therefore, 100 counter
increments correspond to 1 mm. They also determine the decimal point (DEC) and display
divisor (ADI).
If a free factor has been programmed, this factor will be applied and ADI as well as DEC must
be programmed additionally. If the display is reconfigured afterwards and a fixed resolution
step set, the free factor and ADI continue to be stored and can be reactivated via the
configuration on the device; however, they will no longer be valid and will not be used for
determining positions.
Calculation of the free factor
The calculation of the factor to be set is explained in the examples below.
Example 1:
Display of 2 mm / spindle revolution desired.
Scale used: pole wheel with 36 poles of each 5 mm.
Display = measured value x factor
1 revolution = 36 poles x 5 mm = 180 mm corresponds 18000 counter increments.
Display: 20 increments / revolution = 20 incr. / 18000 = 0.0011111
Factor = 0.0011111
Display = measured value x 0.0011111
The transfer value fort he free factor is interpreted as fixed comma value with 1 digit before
the comma and 4 digits after the comma. In order to achieve optimum accuracy, the factor is
multiplied by 10 digits until 4 digits after the comma containing information are obtained.
Factor = 0.0011111 x 10 x 10 = 0.1111 => transfer value 01111dec = 457hex
exponent = 2
The resulting decimal power (exponent) is it with the parameter ADI = 2. The decimal point
must be inserted with the parameter decimal place = 1.

Example 2:
AP04S with "double carriage": Spindle whose thread runs in the opposite direction and 2 carriages, e. g. 5 cm travel distance of one carriage (sensor) result in 10 cm travel distance
between both carriages, display in 1.00 mm desired
scale used: MB500
Factor = 2.0 => transfer value = 20000 = 4E20hex
ADI = 0
DEC = 2
Example 3:
Display in 0.1° desired
scale used: Pole wheel with 64 poles of each 5 mm.
1 revolution (360°) = 64 poles x 5 mm = 320 mm corresponds to 32000 counter increments
Display: 360.0° / revolution = 3600 / 32000 = 1.1250
Factor = 1.1250 => transfer value = 11250 = 2BF2hex
ADI = 0
DEC = 1
Example 4:
Display in 0.01° desired
scale used: Pole wheel with 188 poles of each 5 mm.
1 revolution (360°) = 188 poles x 5 mm = 940 mm corresponds to 94000 counter increments
Display: 36000 / revolution = 36000 / 94000 = 0.3829787
Factor = 0.3829787 => transfer value = 03830 = EF6hex
ADI = 0
DEC = 2

Sensor
Mounting of the sensors as well as installation of the sensor cable is explained in the
documentation pertaining to the sensor MS500H or GS04.
With 24 V supply voltage operation the display controls the connected sensor. If no sensor is
connected or if sensor is detached from the magnetic tape, this is interpretated and displayed
as "Error" (blinking display). Even after an interruption of the voltage supply, the "Error"
display will persist. In this case, please check sensor connection / position. Then carry out
calibration (see chapter 2.4 Keys and chapter 7.2 Calibration) for eliminating the "Error"
display. If both battery supply and power supply fail simultaneously (e. g. during a battery
change), the absolute position value can get lost. For making the measuring system work
again, calibration is required (see chapter 7.1 Alignment travel and 6.2 Errors).

word or status word (see chapter 8.3 System Status Word and accoordingly chapter 9.3.5
Status word).
6.2
Errors
Error states are signalled via display and interface.
Pending errors can be read via the interface. For returning to normal operation, the errors
must be acknowledged or deleted via the
key or bus interface.
(For signaling and acknowledging in the service protocol see chapter 8.3 System Status Word

7.1
Alignment travel
AP04S is fully functioning at the time of delivery. However, in order to adjust the display unit
to the connected sensor and to achieve optimum measuring accuracy, carry out an alignment
travel whenever a new/different sensor is connected to the AP04S. The sensor must be
mounted properly before alignment (see documentation MS500H or GS04).
1.
By entering CODE 00100 AP04S will be set to the alignment mode after confirmation of
the display direction (see Table 10: Start access to alignment).
Display:
1st line.
"Bagel_"
2nd line. "_XXX" with XXX showing a value around 100.
2.
When connecting sensor MS500H, it must be moved by a few millimeters in the direction
of the cable outlet (speed < 1 cm/s).
When connecting sensor GS04, the shaft must be rotated clockwise by a few millimeters
(speed < 1 cm/s).
In the lower line, the value will change in positive direction up to "103".
3.
The alignment process will be completed when this value is finally exceeded. AP04S has
returned to normal operation and shows the corresponding display. If values above 103
are displayed during alignment, then travel speed must be slowed down during alignment.
4.
It is not unusual that the position value cannot be displayed immediately after alignment
travel and "FULL" is displayed instead of the value. The display should be calibrated in
this case (see chapter 7.2 Calibration).
Alignment can be started as follows.

Calibration
Two steps are required for executing calibration:
1.
Enter/write calibration value (see chapter 3.4.1.6 Positioning and chapter 9:
Communication via SIKONETZ5  Parameter address 0x1F)
2.
Execute calibration (reset) (see chapter 2.4 Keys, chapter 3.4.1.6 Positioning or chapter 9
Communication via SIKONETZ5  Parameter address 0xA0)
Since the measuring system is an absolute system, calibration is necessary only once with
commissioning. With calibration, the calibration value is adopted for calculation of the
position value. The following equation is applied in case of calibration:
Position value = 0 + calibration value + offset value
Calibration value (see chapter 4 Parameter description  Parameter no. 26)
Offset value (see chapter 4 Parameter description  Parameter no. 25)

Communication via Service Protocol
8.1
General
The service protocol enables parameterization and control of the position indicator via ASCII
commands. No additional devices must be connected to the RS485 interface since this
protocol is not bus-compatible.
An ASCII terminal sends a letter and additional parameters if required (ASCII).
Subsequently, the position indicator sends a reply with a concluding <CR>.
8.2
Available baud rates:
19.2 kBit / 57.6 kBit (factory setting) / 115.2 kBit
Additional settings:
No parity, 8 data bits, 1 stop bit, no handshake

Data exchange
The protocol functions according to the master – slave principle.
The actuator acts as a slave. Every instance of communication must be initiated by the
master. When the master has sent a command telegram, the slave sends a reply telegram.
Broadcast commands are an exception, they remain always unanswered by the slave.
The protocol is optimized for cyclical data exchange. The relevant data such as set point and
actual value as well as control and status words can be transferred between master and slave
by a single telegram exchange.
The parameter to be returned by the slave as a reply to the master's Write set point command
can be defined via the "Write set point reply parameter".

The master requests the addressed slave to accept
the value transferred in the same telegram.
The master requests all connected slaves to execute
the command transferred in the same telegram.
Node address
The device address can be freely set in the range of 0 to 31. The delivered devices are preset
to node address 1 ex works and must be reset to the desired address to enable their operation
with multiple slaves on the SIKONETZ5 fieldbus. Each address can be assigned in the fieldbus
only once!
Description see chapter 4 Parameter description  Parameter no. 3.
9.3.3
Parameter address
A distinct address is assigned to every parameter (e. g. calibration value) or functional value
(e. g. set point). Description see chapter 9.8 Parameterization via SIKONETZ5.

Data

Check sum
For checking error-free data transfer, a check sum is formed at the end of the telegram. The
check sum is the exclusive-OR-link of bytes 1 … 9:
Check sum [Byte10] =
[Byte1] XOR [Byte2] XOR [Byte3] XOR [Byte4] XOR [Byte5] XOR [Byte6] XOR [Byte7] XOR
[Byte8] XOR [Byte9]
The following applies for checking the telegram received:
[Byte1] XOR [Byte2] XOR [Byte3] XOR [Byte4] XOR [Byte5] XOR [Byte6] XOR [Byte7] XOR
[Byte8] XOR [Byte9] XOR [Byte 10] = 0
With a result unequal 0 a transmission error is to be assumed.
9.4
Synchronization
Processing of the "Restore factory settings" system command may take up
to 100 ms. Acknowledgment is reported only after proper updating of all
parameters in the non-volatile memory.
Byte/telegram synchronization is via "Timeout". The intervals between the individual bytes of
a telegram must not exceed the value of 10 ms. If an addressed device does not respond, the
master must not send another telegram earlier than after 30 ms.

Error telegram
Illegal entries are replied with an error telegram.
An error telegram consists of parameter address 0xFD and an error code.
The error code is in the data section of the reply telegram. The error code is divided in two
bytes. Code 1 describes the error proper, code 2 contains additional information if available.
In the following example an attempt was made at writing a value of 90 to the key enable time
parameter address.
However, a maximum value of only 60 is admissible for this parameter.

9.6
Errors
If a slave is in the error state the slave signals the error with SW.7 = 1.
An error must be acknowledged by CW.5 = 0/1 or by pressing the
key. If the cause of the
error has not been resolved at the time of acknowledgment, the error will not be reset or
triggered anew, resp.
Errors that have not been acknowledged can be read via a read command on Parameter
address 0xFD. The error code will be output (see chapter 6.2 Errors and 9.5.1 SIKONETZ5 error
codes).
9.7
Communication monitoring
9.7.1
Bus Timeout
Bus timeout monitoring is activated via parameterization of a valid time value (>0) for
timeout (see chapter 4 Parameter description  Parameter no. 6).
The first telegram received by the slave starts time monitoring.
Every new telegram recognized as valid by a slave (correct check sum) triggers time
monitoring.
If timeout occurs, this will result in the Timeout error.
After establishing cyclic communication between master and slave, this function can detect a
broken cable of the connection line for instance and signal the defect.
9.7.2
Programming interlock
Programming interlock is controlled via Parameter no. 21: "Programming mode configuration"
This parameter being enabled, the interlock must be canceled prior to write access to a
lockable parameter (see Table 7: Parameter description) by applying a write access to
Parameter no. 22: "Programming mode." Correspondingly, the interlock should be enabled
again immediately after a write access.
This mechanism enhances protection against unintentional parameterization.
Write access to locked parameters is replied with "Error due to device state" (see chapter
9.5.1 SIKONETZ5 error codes).
9.8
Parameterization via SIKONETZ5
On principle, the position indicator sends a telegram acknowledging write and read commands
of the master. With the command executable the value adopted is in the reply telegram.
If the actuator was unable to execute the command, e. g. because it attempted to write a
value beyond the admissible range, the position indicator will send an error telegram in reply.
