6.9.4 Communication Management

6.9.4.1 DCP (Discovery and Configuration Protocol) is used for basic management of stations (especially setting of

IP-address and Device name). DHCP (Dynamic Host Configuration Protocol) can be used as configuration option.

6.9.4.2 Connectionless DCE RPC is used as an interface between transport and application.

6.9.4.3 “Identification & Maintenance Functions” (I&M functions) define general parameters and protocols. The

main purpose of the I&M functions is to support the end user during various scenarios of a device’s life cycle be it

configuration, commissioning, parameterization, diagnosis, repair, firmware update, asset management, audit

trailing, and alike. Well-defined uniform parameters and rules should enable the manufacturers to offer devices that

behave in a uniform manner These profile guidelines take into account requirements from FDA (Food & Drug

Administration) and others. The basic information offered can be characterized as “Type Plate” or “Boiler Plate”. It

consists of Manufacturer ID, Order ID, Serial Number, Hardware Revision, Software Revision, Revision Counter,

Profile ID.

7 Required Object Types

7.1 This section describes a general mapping of the SEMI SAN Object Model to the PROFINET environment.

Component definitions are clarified and the mapping of Attributes, Services, and Behaviors are specified.

7.2 Object Model

7.2.1 The Object Model defined in the CDM is represented in the PROFINET NCS. Specifically, the DM and SAC

objects are mapped.

7.2.2 The CDM Objects are mapped to slots. These slots have a unique address space within the device. The

Specific Application Objects are mapped in PROFINET Device Data Base. §9 specifies the mapping of SDM

Objects in PROFINET.

7.3 Component Mapping Summary

7.3.1 Figure 4 provides a summary of the components of the CDM object model as they relate to the components of

PROFINET.

7.4 Objects

7.4.1 The required objects of the CDM are identified here. Additional objects that are contained in the SDM are

given identifiers in the Device Profile. §9 specifies

additional mapping information.

7.4.2 Table 2 lists the Object Identifiers specified for use

in protocol messages. Slot numbers is the mechanism

used for addressing Objects within PROFINET. Subslot

IDs can be used for sub addressing. Within this NCS the

subslot 1 shall be used as default subslot.

7.4.3 Assembly Objects and Local Link Objects which

are objects embedded in the SAC Object are not explicitly

mapped in PROFINET.

7.5 Attributes

7.5.1 General

7.5.1.1 All attributes are accessible via Get_Attribute and

Set_Attribute services defined in the sections below. The Get_Attribute and Set_Attribute services shall be mapped

to PROFINET Read and Write services for Record Data objects. Additionally, attributes are accessible via different

PROFINET defined methods that are mapped in this document based on attribute type.

7.5.2 DM Attributes

7.5.2.1 All attributes are communicated with Read and Write Service and mapped to IM Blocks. Status attributes

are modeled additionally as Diagnosis. See Table 17 for detailed mapping.

7.5.2.2 Table 3 shows the DM status attribute mapping to Diagnosis.

Error Type 9 = Error with Bit0 - 6 set in Common Exception Detail 1

21 = Error Calibration set in Common Exception Detail Attribute 1

17 = Error with Bit set in Common Exception Detail 2

7.5.3 SAC Attributes

7.5.3.1 The attributes of SAC are mapped to Record data objects of PROFINET.

7.5.3.2 The Slot number used is 0. The index is the numeric value of the SAC Attribute identifier with an offset of

64 (see Table 4).

7.5.4 Active Element Attributes

7.5.4.1 The attributes of Active Elements are mapped to Record data objects of PROFINET. These attributes are

contained in any Sensor, Actuator and Controller Object.

7.5.4.2 The Slot number used is the instance number in the device. The index is the numeric value of the Active

Element Attribute identifier with an offset of 64 (see Table 5).

7.5.5 Sensor Attributes

7.5.5.1 The attributes of Sensors are mapped to Record data objects of PROFINET. These attributes are contained

in any Sensor-AI, Sensor-EI and Sensor-BI Object.

7.5.5.2 The Slot number used is the instance number in the device. The index is the numeric value of the Sensor

Attribute identifier with an offset of 64 (see Table 6).
