3.7 Service Models
The service models allow to process an object; a part of the object is implicitly specified (for example it is
determined by the interface PMS). The other part is explicitly specified in the object dictionary (called OV).
The access to an object is possible through some services and the addressing can be logical (through an
index) symbolical or implicit.

4.1 Context Management Services
The services regarding the system control are the following:
Initiate
Abort
Reject.
4.1.1 Initiate
This service can establish the connection between two communication Partners. To achieve this, there is an
information exchange about the possible services accepted and the length of PDU.
4.1.2 Abort
This service terminates the previously established connection between two communication Partners.
4.1.3 Reject
With this service PMS rejects a non-allowed PDU.
4.2 Variable Access Services

Variable Access Services
4.2.1 Read
This service gives the possibility to read the values of a parameter, an array or a structure. As far as arrays
and structures are concerned, their values can be entirely read (by setting the subindex to zero) or read the
elements one by one (by setting in the subindex the number of the element involved in the operation).
4.2.2 Write
Interbus -
This service gives the possibility to write the values of a parameter, an array or a structure. As far as arrays
and structures are concerned, their values can be entirely written (by setting the subindex zero) or written the
elements one by one (by setting in the subindex the number of the element involved in the operation).
S
4.2.3 Information Report
This service is an information message carried out by the Slave in the Master direction: this service has not
been previously required by the Master.
The Slave generates this service when for example it has to indicate an alarm condition.
4.3 VFD Support Services
The following VFD services are supported:
Status
Identify.
4.3.1 Status
The status of the user device (Slave) can be read through this service.
4.3.2 Identify
Information suitable for the identification of VFD (and therefore of the user device) can be read with this
service.
GEI- 100445
5.0 DRIVE PARAMETERS
The user parameters have an Offset referred to the type of drive linked to Interbus-S; in order to obtain the
parameter index, the specific Offset for that drive has to be added to the index of the drive parameter.
At present the Offsets are the following:
DRIVE OFFSET (in
hexadecimal)
AV300 2000hex
DV300 2000hex
Example:
The DV300 drive parameter having the index
the index 200Fhex.
The Drivecom parameters start with the index 6000h (hexadecimal); for their indexes see paragraph
5.2.1.1.4.2 of the manual
The Drivecom parameters for the configuration of the process data channels
implemented on all the cards in order to allow the configuration of the above-mentioned channels, which are
later described.

6.0 HOW TO COMMUNICATE
Communicating is possible through a series of services demanded by the Master to the Slave; such services
are:
-

information Report
In order to communicate through the Communication Channel it is necessary that the Master sends to the
Slave a request to initiate the communication (Initiate Service) and that the Slave acknowledges a positive
response.
After the
reading and writing.
The Slave can only carry out the services requested by the Master; it can not ask for any service: only with
the Information Report can the Slave carry out a service for the Master without it being asked previously.
When the Master asks the Slave to read a parameter, it must send the parameter index and eventually the
subindex; if the data is correct, the Slave responds positively with the parameter value, otherwise it responds
negatively indicating the error cause.
As for writing a parameter, the Master sends to the Slave the parameter index, eventually the subindex and
the writing value; in this case the Slave responds positively if the writing has been carried out successfully
otherwise it responds negatively indicating the error cause.
The Slave always verifies the validity of the index, of the subindex, of the access rights and in the case of
writing the length of the value sent and if the value is in range of the stated limits; it verifies also if in that
moment the parameter can be written.
As for error codes, the composition and the meanrng of the different services, see the Reference Manual for
InterBus-S ( see reference chapter).

The alarms regarding Interbus-S are:

Description
Bus
Loss; if an accidental interruption of the connection occurs, this alarm is generated; the
visualization of the corresponding alarm message depends on the drive configuration.
SBI Hardware Fault; if the Interbus-S interface card is faulted, this alarm is generated; the visualization
of the alarm message depends on the drive configuration.
SBI Ram Fault; this alarm is generated if there is a fault in the Dual-Port-Ram of interface between the
drive and the InterBus-S card;the visualization of the alarm message depends on the drive
configuration.
7.2 Communication Status
In case of alarm the behaviour of the interface
following cases must be distinguished:
l-
The communication between the Master and the drive has already been established; more precisely it
means that the Peripherals Communication Protocol (PCP) IS active and therefore the Initiate Service
has already successfully been carried out.
2-
The communication between the Master and the drive has not been established yet; it means that the

N.B. The concept of established communication makes reference to the activation of the Peripherals
Communication Protocol (PCP); it means that the Process Data Channel is active in any way and the
data exchange through this channel takes place regularly.
7.3 Alarm Recovery
The description of the behaviour takes into consideration the above-mentioned communication status; it is
necessary to remember, anyway, that what will be described depends on how the drive has been set to
handle the alarm; in the following description it is assumed that the drive totally handles the alarm of Field
Bus
Loss.
1 - First case of communication status
a - Reaction to the alarm.
If the above-mentioned conditions are respected, in case of InterBus-S alarm the drive stops
immediately the motor, displays the alarm message and waits for its recovery; the InterBus-S
interface card interrupts the data transfer of the Process Data Channel outcoming from the Master by
clearing the parameter

If the Bus control has not been stored in the drive, control must be recovered by acting as
required by the drive (see relative manual).

2 - Second case of communication status.
In this case the
If the Peripherals Communication Protocol is not active, the Master can not control the drive; be aware that
the Process Data Channel has been enabled and therefore the exchange of data can be carried out through
it; more precisely the data outcoming from the Master and incoming in the drive (PDC Output) are transferred
but they are not active because the parameter
active after the setting of this parameter, while the data incoming in the Master and outcoming from the drive
(PDC Input) are always active.
This is valid only if the Process Data Channel has already been configured by setting the parameters 6000h
for the data incoming in the Master and 6001 h for the data outcoming from the Master.

3 - Third case of communication status.
This case is similar to case number two because the Peripherals Communication Protocol is not active; the
above-mentioned considerations are valid too.
We should emphize the behaviour in case the Abort service is successfully carried out while the drive is
active, i.e. it is controlling a motor (the Abort service should be never carried out under this condition).
The card acts in the following way:
The command ‘Drive Stop’ is sent to the drive.
The data of the parameters PDC Output are cleared (data outcoming from the Master; incoming
in the drive).
The Process Data Channel outcoming from the Master and incoming in the drive (PDC Output)
is disabled by clearing the parameter ” PDC Output Enable”.
Note that the drive does not display an alarm message because this case is not considered a real alarm.

At the beginning it is suggested to supply power first to the drive and then the Master;
when the Master has terminated successfully the identification cycle, proceed as follows:
l-
Establish the connection by activating the Peripherals Communication Protocol by successfully
carrying out Initiate service.
2-
If the Bus control has not been stored in the drive, activate such control by acting as required by
the drive (see relative manual).
Configure the Process Data Channel by setting the relative parameters (see chapter 6).

Enable the Process Data Channel outcoming from the Master (PDC Output) by setting the

To switch off the system or stop the connection proceed as follows:

Stop the motor and disable the control by acting as required by the drive (see the relative
manual).

significant Byte to the most significant one.
The elements of this Record can be read one by one, by entering the subindex or all together (by setting the
subindex to 0) .

c)
Element V-PAR with DGF parameter value (4 Bytes have always to be written; in the case of
d)
DGF parameters with a length less then 4 Bytes fill the remaining Bytes with 0).
The elements with more than one Byte must always be filled starting from the less significant Byte to
the most significant one.
2-
Carry out the InterBus-S ‘Write’ service by always setting the Interbus-S subindex to 0 and wait for
the response.
3-
If the response is positive, the value of the DGF parameter has been correctly written.
4-
If the response is negative, the error cause can be found by reading, with the Interbus-S “Read”
service , the Result element (operation result) of the Interbus-S parameter 5EFBh. The single element
can be read by setting the subindex to 1, or the whole parameter can be read by setting the subindex
to 0 (in this case the V-PAR element has no meaning).
