4. Layout of the protocol data packet
The fieldbus module transmits the system status as well as the status and diagnostic elements for all inputs/outputs that
are configured in the MSC system, and makes it possible to read up to 32 separate fieldbus inputs.
The input and output structures are described in chapters 4.1 and 4.2.
The input structure consists of up to four bytes that represent the fieldbus inputs. The number of input bytes depends on
the firmware version of the fieldbus module, see Table 2.
Fieldbus module rmware version Size of input structure
< 2.0 1 byte (8 fieldbus inputs)
≥ 2.0 4 byte (32 fieldbus inputs)
Table 2: Fieldbus input structure
FW ≥ 2.0
The base unit MSC-CB can process only 8 fieldbus inputs, which is why only the first byte in the input
structure is used.
FW < 2.0 The base unit MSC-CB-S can process up to 32 fieldbus inputs, but only the first byte is transferred due
to the limitation of the input structure.
FW ≥ 2.0
The output structure comprises:
Ìone status byte,
Ìone reserved byte,
Ì16 bytes for the status of the inputs,
Ì4 bytes for the feedback of the fieldbus inputs,
Ì4 bytes for the status of the fieldbus outputs,
Ì4 bytes for the status of the safe outputs,
Ì64 bytes reserved for analog data that are not available in the current EUCHNER portfolio,
Ì64 bytes for diagnoses
FW < 2.0
The output structure comprises:
Ìone status byte,
Ìa variable number of bytes for the status of the inputs (max. 16 bytes),
Ìone byte for the feedback of the fieldbus inputs,
Ìtwo bytes for the status of the fieldbus outputs,
Ìa variable number of bytes for the status of the safe outputs (max. 2 bytes),
Ìtwo bytes for diagnoses
The system status is indicated by one byte:
ÌBit 0 indicates whether the MSC system is online or offline
ÌBit 1 indicates whether diagnostic information is available
ÌBit 2 indicates whether there is an error in the MSC system (only firmware version ≥ 2.0)
Each input and each output (OSSD) that is configured in the MSC system is linked to two information elements: Status and
Diagnostics.
Status is a binary value, 0 or 1, Diagnostics is a code for the indication of the IO state, which can be in correct working
order, or which can be indicative of a problem on the I/O.
Each module with inputs has a number of bits that corresponds to the number of inputs present. For this reason, the modules
MSC-CB, MSC-CB-S, FI8, FI8FO2 and FI8FO4S are linked to one byte (8 bits) and the modules FI16 and FM4 to two bytes
(16 bits) for the input status.
Depending on the type of the respectively installed modules, the position of the inputs varies in the following sequence: MSC-
CB/MSC-CB-S, FI8FO2, FI16, FI8, FM4, SPM2, SPM1, SPM0, FI8FO4S. If several modules of the same type are installed,
the order corresponds to the node number.

All safety outputs are combined in up to 4 bytes, depending on the firmware version of the fieldbus module, see Table 3.
The dual-channel safety outputs are transmitted as a bit via the fieldbus.
Fieldbus module rmware version Size of safety output structure
< 2.0 up to two bytes
≥ 2.0 4 bytes
Table 3: Safety output structure
FW ≥ 2.0 The base unit MSC-CB can process only 16 bits at the safety outputs, which is why only the first two
bytes of the safety output structure are used.
FW < 2.0
The base unit MSC-CB-S can process up to 32 bits at the safety outputs, but only the first 16 bits of
the safety output structure can be transferred due to the limitation of the fieldbus module.
Depending on the type of the respectively installed modules, the position of the safety outputs varies in the following se-
quence: MSC-CB/MSC-CB-S, FI8FO2, AC-FO2, AC-FO4, AZ-FO4, AZ-FO4O8, AH-FO4SO8, FI8FO4S. If several modules of the
same type are installed, the order corresponds to the node number.
A diagnostic element consists of an index of the I/O with a problem and a diagnostic code of the problem.
FW ≥ 2.0
The diagnostic area in the output structure comprises 64 bytes, and the first 23 diagnostic elements
are therefore sent via the fieldbus simultaneously.
FW < 2.0 The diagnostic area in the output structure comprises two bytes, which is why only one diagnostic
element can be sent. With several diagnostic elements, the relative values change every 500ms.
FW < 2.0 Each information set:
ÌInput status
ÌInput diagnostic
ÌFieldbus input status
ÌProbe State
ÌSafety output status
ÌSafety output diagnostic
can be activated/deactivated to control the information and therefore the number of bytes sent to
the fieldbus.
NOTICE
ÌThe input and output structures are represented from the viewpoint of the MSC system.
ÌOn fieldbuses in which the data frames are specified (e.g. PROFIBUS), the input bytes must pre-
cede the output bytes.

Status of the eldbus outputs
(FIELDBUS PROBE) (4 bytes)
Each bit represents the status of a fieldbus output in the project plan. Max. 32 fieldbus output bits can be
used.
Status of OSSD/relay (4

Each bit represents the status of an OSSD/relay. The position of the bits corresponds to the sequence:
MSC-CB/MSC-CB-S, FI8FO2, AC-FO2, AC-FO4, AZ-FO4, AZ-FO4O8, AH-FO4SO8, FI8FO4S.
Reserved for the status of
the analog inputs (64 bytes)
Diagnostics (64 bytes) Each input or safety output function block is linked to the diagnostic code. The system exports 2 bytes on
the fieldbus for every diagnosis:
ÌThe index for the related I/O
ÌThe diagnostic code
NOTICE
Refer to the “Diagnostics” chapter in this manual for more information about the indices of the I/Os
and the diagnostic codes. If I/O is “OK,” the system exports two bytes to the fieldbus with
Ì0 as index value
ÌDiagnostic code OK (0x80)
NOTICE
If a fieldbus module is used in the MSC system, the EUCHNER Safety Designer report contains a table
with the I/O index for all inputs, the fieldbus input, the fieldbus output (PROBE) and the safety outputs
in the circuit diagram.
The maximum number of inputs that can be administered in an MSC system is 128, which is why the size of the sub-section
“Inputs States” is 16 bytes (128/8).
The maximum number of safety outputs (OSSD/relay) that can be administered in an MSC system is 32, which is why the
size of the sub-section on the OSSD/relay status is 4 bytes (32/8).
FW < 2.0
The scope of the sub-sections “Inputs States” and the OSSD/relay status depends on the hardware
configuration in the MSC system. The sub-section on the OSSD/relay status is limited to 2 bytes here.
The reserved areas are not transmitted, and the Diagnostics sub-section comprises only 2 bytes.
The input and output structures can be graphically depicted in the Bus Configurator – User Interface, see Figure 4.

4.3. Conguration of the input and output structure
FW < 2.0
The input and output structure can be configured using the software application Bus Configurator
– User Interface. Backward compatibility must be set under Settings -> Activation for this purpose.
Important!
The compatibility mode functions only in combination with a base unit MSC-CB or with a fieldbus module
with a firmware version < 2.0.
Figure 5: Bus Configurator – User Interface, compatibility mode
FW < 2.0
The “Backward Compatibility” tab appears after the compatibility mode is set, see Figure 5. The “I/O
Select” area can be used to define the sub-sections to be exported on the fieldbus. In this way, the
size of the structure and therefore the usage of the internal memory in the PLC can be defined.

5. Diagnostics
Each input and each safety output is linked to a relative diagnostic code.
If the I/O is connected correctly, the system exports 2 bytes to the fieldbus:
Ì0 as index value
ÌDiagnostic code OK (0x80)
If there is a problem on the I/O, the system sends two bytes to the fieldbus with:
ÌThe index for the related I/O
ÌThe relative diagnostic code
5.1. “I/O index” eld
This field indicates the number of the I/O with the diagnostic code that is not OK. The area of the I/O index depends on the
base unit used. The possible values are shown in Table 8.
