Description
The F1X5_ is a mono-bidirectional microprocessor multiple keyboard counter, that processes signals
supplied by incremental transducers (encoders, optical lines, etc…) on a 5 digit display (reading scale –99999
+99999). The programming of this microprocessor is carried out by means of four keys on the frontal panel,
after introducing a password. The microprocessor allows the operator to set the input pulse correction
factors, and to multiply these factors by a 6 digit coefficient. The device has a serial output connection RS485
(or RS232) with MODBUS RTU protocol to dialogue with remote units. This instrument can keep its data in
memory also when the machine is switched off thanks to a not volatile Eeprom memory. The Reset-Enter
digit is employed to input a Preset quote too. By means of the input located on the terminal-board you can
switch on the Reset or Preset functions. This instrument is set inside a 48 x 96 panel case according to DIN
43700.

Installation
Before installing the instrument, read the following warnings:
a) Connect the instrument strictly following the instructions of the manual.
b) Carry out the connections using the correct wires within the limits of the tension and power supply as indicated
in
the technical data.
c) The instrument does not have an ON/OFF switch, hence it comes on when connected to the power supply. For
safety reasons, the equipment connected permanently to the power supply requires a bi-phasal selector switch
which should be within easy reach of the operator.
d) If the instrument is connected to any apparatus not isolated electrically, carry out an earth connection to avoid it
being connected directly through the structure of the machine.
d) It is the responsibility of the user to check, before using, the correct settings of the parameters of the instrument
to avoid damage to persons or things.
e) The instrument cannot function in a dangerous environment (inflammable or explosive). It can be connected to
elements that operate in the same atmosphere only through appropriate interfaces, according to the current safety
regulations.
g) Avoid dust, humidity, corrosive gases, heat sources.
h) Do not block air vents, the work temperature should be maintained between 0 ÷ 50°C.

Power supply
a) Before connecting the instrument, check that the the power supply tension is within the permitted limits and that
it corresponds to the one indicated on the tag.
b) Carry out the electrical connections with the instrument disconnected.
c) For the power line to instruments and sensors, a power supply line separate from that of the power is required :
it is necessary to use an isolating transformer.
d) The power line should forsee a device that separates the set fuses of the instruments and should not be used to
regulate, meters, etc.
e) If the network tension is very disordered (eg. from the change-over of the power units, motors, inverters,
welders,
etc.), use the appropriate filters of the network.
f) If an earth connection is needed, ensure that the plant has a good earth system: tension between neutral and
earth <1V and the resistance <6 Ohm.
Connections entries and exits
a) Physically separate the entry wires from those of the power supply, the exits and the power connections; use
twined and shielded wires with the display connected to the earth only at one point.
b) Connect the exits of adjustments, alarms (meters, electrovalves, motors, ventilators, etc.) assembling units RC
(resistance and condenser in series) parallel to the charged inductives that work alternatively.
Assembly of the instrument
To carry out the correct installation of the instrument, it is necessary to follow the shown procedure:
1. Insert the instrument in the opening provided.
2. Screw the screw on the fixing block.
3. Hook the block to the instrument through the joints.

Value which Corresponds to 1 Encoder Revolution
This instrument can correct the impulses, and multiply them by a coefficient, which corresponds to the ratio
between constant and . If you programme these two constants correctly the display will
visualize the value you need with a certain number of impulses (they are reckoned in the inputs). The
programmed value of this parameter represents the value visualized on the display.
The interval value of this count is programmable between 0 ÷999999.
Number of Impulses for every Encoder Revolution
The value, which should programmed in this section, represents the number of impulses for every encoder
revolution, this is to say the division factor of input impulses.
The interval of the allowed values is 0 ÷999999.
Example 1:
If you have a 100 impulse/rev. Encoder, and for every revolution you need to visualize 123,4567 pls. follow
the next description: VISUAL=1234 and IMPULS=100 . If you need to input a decimal number in the second
position too, pls. insert N.DEC=1.
N.B:In order to reduce the approximation error we suggest you to multiply VISUAL and IMPULS by 10 or 100 or
1000 . With reference to the above mentioned values you will get :123.4567 x 100 =123456 and
IMPULS=10000.
The value will be composed by 6 numerals (instead of 4) for every visualization.
Example 2:
If you have a proximity sensor, and after 10 impulses you need to see the value 7, pls. programme in the
following way: VISUAL=7 and IMPULS=10.
Decimal Numbers
This constant shows the decimal point position : programme 0 if you have not any decimal number, 1 for 1
decimal number, ecc… Accepted values: from 0 to 4.
Preset
This instrument allows you to programme a value which will be shown after pressing RESET/ENTER or after
activating the Reset input in the key-board according to the scheme M.Azz. “Zero setting” .
The allowed values are included between –999999 and 999999.
Zero setting
By means of the zero-setting programming you can select the function of the instrument after choosing the
RESET/ENTER digit or after starting the RESET in the terminal board.
The Reset function zeros the visualized quote on the display, while the Preset shows the value, which has been
programmed in the constant before hand.
According to the following scheme, please choose your preferred type of zero setting :
PRESET Input RESET/ENTER Digit
0 Reset Disabled Digit
1 Preset Disabled Digit
2 Reset Reset
3 Reset Preset
4 Preset Reset
5 Preset Preset

Inputs
By means of this constant you can programme the input types, and count according to the following scheme:
Input
0 Bidirectional count from an encoder with 2 quadrate channels
1 Monodirectional count with input coming from a sensor or a mechanical
contact :
A = count impulses (from open to closed)
B = count direction: when B is open, the count increases,
when B is closed the count decreases *
2 Monodirectional count with input coming from a sensor or a mechanical
contact:
A = Count impulses (from open to closed)
B = count direction: when B is open the count increases,
when B is closed the count decreases
3 Bidirectional count with inputs coming from sensors or mechanical
contacts :
A = Increasing count impulses from open to closed phase
B = Decreasing count impulses from open to closed phase
4 Bidirectional count with inputs coming from sensors or mechanical
contacts :
A = Increasing count impulses from closed to open phase
B = Decreasing count impulses from closed to open phase
* B has to be connected to GND if the sensor is NPN; to +12V if the sensor is PNP ( see connection scheme )
Debounce Filter for Count Inputs
If you use an input coming from a mechanical contact in order to avoid debounce impulses you have to
programme this constant “1”. In this case you can start a filtre of 10Hz in the count inputs, which avoids
interferences in the opening or in the mechanical connection of the instrument.
This constant can have only a 0 value (except for the filtre), and 1 (working filtre).[ It does not matter if you
chose a bidirectional encoder with quadrature channels in the opening phase! ( INPUT CONSTANT = 0)].

MODBUS PROTOCOL OF SERIAL PORT CONNECTION
The device has a serial output connection RS485 (or RS232) with MODBUS RTU protocol to dialogue with
remote units, 8bit data; 1 bit di stop; no parity. The Protocol is based on a QUERY/RESPONSE structure: the
slave devices reply to the queries with a message that contains the identifying address and the requested
data. It is possible to read and write the parameters of the F1X5_RS, called configuration registers.
The MODBUS protocol ensures the validity of the exchanged data through the line by a “Cyclic Redundance
Check” error check; two CRC bytes of are added to the messages. The algorithm to make two bytes of CRC
in Pascal language and C is provided.

Further Information on the making of the two CRC bytes are available on the site www.modicon.com.
The F1X5 MODBUS commands are:
0x03: multiple reading of registers
0x10: writing of several registers.
0x03 READING OF REGISTERS
To read the registers of the instrument, the master must send a query composed as follows (every element is
a byte):
ADDRESS | 0x03 | START_REG_HI | START_REG_LO | N_REG_HI | N_REG_LO | CRC_HI | CRC_LO
- START_REG_HI | START_REG_LO is the address at the starting 16 bit for the reading
- N_REG_HI | N_REG_LO is the number (16 bit) of the registers to be read
The instrument replies with the following message:
ADDRESS | 0x03 | NBYTE | DATA_1_HI | DATA_1_LO | DATA_2_HI | DATA_2_LO | …
| CRC_HI | CRC_LO
- DATA_1_HI | DATA_1_LO | DATA_2_HI | DATA_2_LO | … is the sequence of the data
read..
NBYTE is the number of the given bytes that follow
0x10 WRITING OF REGISTERS
To write the registers of the instrument, the master must send a query composed as follows (every element is
a byte):
ADDRESS | 0x10 | START_REG_HI | START_REG_LO | N_REG_HI | N_REG_LO | NBYTE | DATA_1_HI |
DATA_1_LO | DATA_2_HI | DATA_2_LO |…… | CRC_HI | CRC_LO
NBYTE is the number of the given bytes that follow.
The instrument replies with the following message:
ADDRESS | 0x10 | START_REG_HI | START_REG_LO | N_REG_HI | N_REG_LO | CRC_HI | CRC_LO
ATTENTION!!: to make operative the new value introduced you must send the “reload parameter”
command writing in the Operation Register (*) (address 0x15) the value 0x01.
Exceptions management:
In case the slave recognizes an error in the query received and addressed to it, it replies with an exceptional
message composed as following:
ADDRESS | FUNCTION_CODE + 0x80 | EXCEPT. CODE | CRC_HI | CRC_LO
The Exception Code can be one of the following:
01 Æ
ÆÆ
ÆIllegal Function: The function code received in the query is not valid.
02 Æ
ÆÆ
ÆIllegal Data Address: The address received in the query is not valid.
03 Æ
ÆÆ
ÆIllegal Data Value: A value contained in the query is not valid.
