ELEKTRONIK
1.0 General
The REOVIB MFS 268 range of controllers for vibratory feeders can be operated from an RS 232
interface. To do this the frequency controller must be set up to receive serial data, using Menu “C 017”
(S.I.F. = I ). The set point for feeder throughput is adjusted in “Running Mode“ and the controller status
(ready/fault) is transmitted back. The controller can be configured, using the serial interface, in a
further “Parameter Mode“.
Units are available in two versions, panel mounting or enclosed.
The interface allows communication with the frequency controller by using 3 data words (each having
16 bits).
Controllers are always factory configured for interface operation. Should the unit be required for
manual set-up then the Parameter S.I.F. must be set = “0“ in Menu C 017. To return to serial interface
operation S.I.F. must be reset = “1“.
The communication on the interface must be maintained continuously (repeat data string constant),
otherwise the controller gets turned off by an internal “watch dog” after about 2 seconds.
2.0 Serial Interface Data
The Parameters for serial interface are set as follows:-
Baud rate: 9600, 8 Data bits, 1 Stop bit, No Parity, No Handshaking (DTR = +12V, RTS = - 12 V)

ELEKTRONIK
The serial interface information is sent as a character string that is closed with a RETURN (CR) for
synchronization. Within the string there are three used data words each having four characters
(Bytes). The complete data string therefore comprises 3 x 4 + 1 characters.
Each part character string of the data word is the hexadecimal code equivalent of the 16 bit integer
expression of the used data. Only upper case characters "0" to "9" and "A" to "F" are permitted. Each
character is transmitted with 8 bits represented by ASCII code. Each part of the string contains four
characters and if necessary a leading zero is used.
The value range of the used information is depicted in a different manner to the value range of the
internal data format (16 bit integer). To differentiate, the values and the bit coded status information
are relative or absolute, signed or unsigned and limited or unlimited.
Type Signed Limiting Example Value range Form
Relative Not signed Limited Set point,
Setting range
(0..100)% (0000..FFFF)
Relative Not signed Unlimited Effective value (0..200)% (0000..FFFF)
Relative Signed Limited Regulation range,
phase position
(-100..100)% (8000..7FFF)
Absolute Not signed Limited Time, frequency Individual Individually
scaled
bit Status True, false (0000..FFFF)
The character string is controlled by the RETURN’s for the correct length and existence and so invalid
information is disregarded. The watchdog switches the set point to zero if non valid information is
received.
! The string to be sent must be repeated continuously !
Example:
Adjust set point to 70 % and enable ON.
RS 232 Character String: "B33200000004"+CR
3.0 Serial Interface Modes
When serial inteface communication is used there are two basic operating modes:-
Normal operation: Control of the frequency controller in a production process.
In this mode the set point and control signals (On/Off) are transmitted..
Parameter operation: Setting of the frequency controller to the required operating mode and limits.
In a special mode the parameters and their addresses are sent to the
frequency controller and are received back as confirmation
In parameter mode, specific controller values such as frequency, soft start,
time delays, contactor etc. are adjusted.

3.1 Normal operation
In normal operation the serial interface is used to adjust the set point for the feeder throughput and the
digital control signals e.g. the enable. The unit status (ready or fault) is reported.
All data words are in the range 0000..FFFF H.
The communications words are shown in bit form as follows.

3.2 Parameter operation
The unit specific parameters can be read and changed in Parameter Operation.
Before writing parameters a write enable must be sent. Then it is possible to change a single or
several parameters. On closing the write enable must be removed. A read request only is required for
reading
The response value of Word 3 is always “C0DE“ H. This is used by the controller to indicate that it is
running in parameter mode.
3.2.1 Parameter address and value formatting
In parameter operation the most significant bit in Word 1 defines the “read/write” (R/W) bit (1 = Write,
0 = Read) and must be given with parameter address of the corresponding parameter.
Normal or parameter operation are selected by using the mode bit (most significant bit in word 3 (0 =
Normal-, 1 = Parameter operation).
Word 1:
R / W
–
Bit + Address
e.g. 8000 H + 1009 H => 9009 H
Word 2:
Parameter value.
e.g. 7FFF H
Wort 3:
Mode bit = 1 + control b
its
e.g. 8000 H + 0004 H => 9004 H
For bit configured parameters only those bits that correspond to the required characteristic may
be altered. All other bits must not be changed; otherwise the basic settings for the load could be
altered.
The procedure for adjustment using bit parameters is as follows:-
1. Read parameter value.
2. Only alter the required bit value(s) for the parameter which is chosen.
3. Switch on the write enable.
4. Write the changed parameter value back to the same address.
5. Remove the write enable.
