Safety Guidelines This manual contains notices which you should observe to ensure your own personal safety as well as to avoid property damage. The notices referring to your personal safety are highlighted in the manual by a safety alert symbol, notices referring to property damage only have no safety alert symbol. Danger indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. Warning indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. Caution used with the safety alert symbol indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. Caution used without safety alert symbol indicates a potentially hazardous situation which, if not avoided, may result in property damage. Notice used without the safety alert symbol indicates a potential situation which, if not avoided, may result in an undesirable result or state. When several danger levels apply, the notices of the highest level (lower number) are always displayed. If a notice refers to personal damages with the safety alert symbol, then another notice may be added warning of property damage.
Qualified Personnel The device/system may only be set up and operated in conjunction with this documentation. Only qualified personnel should be allowed to install and work on the equipment.

Guide to the PROFINET Documentation Overview
The schematic below provides you with an overview of the PROFINET documentation.
Ethernet > Assign Device Name. You can, for example, use this function to identify a PROFINET IO device you want to address in cubicle.
Further Information on Diagnostics and Blocks For more detailed information on the topic of diagnostics, refer to the PROFINET System Description. For more detailed information on blocks (OBs, SFBs, etc.), refer to the STEP 7 online help and the reference manual System Software for S7-300/400 System and Standard Functions.
See also Diagnostics Mechanism in PROFINET IO (Page 5-6)
5.2
Diagnostics Mechanism in PROFINET IO
Totally Integrated Diagnostic Concept PROFINET IO supports you with a totally integrated diagnostic concept. The basics of this concept are explained below.
Diagnostic Mechanism If a channel error occurs (for example overflow of an analog input), the malfunctioning IO device generates a diagnostic interrupt to the IO controller. This interrupt calls a suitable program routine (OB82) in the user program to initiate a reaction to the error. If a defect means that a device or submodule must be completely replaced, the IO controller automatically assigns parameters to and configures the new device or submodule. Following this, cyclic exchange of user data is resumed.
Diagnostic Data Records in PROFINET IO There are two different types of diagnostic data records: 1. Channel diagnostic data records Channel diagnostic data records are displayed when there is an error on a channel and/or the channel is triggered an interrupt. If there is no error, a diagnostic data record with the length 0 is returned. A maximum of 400 channel errors can be displayed one time. 2. Vendor-specific diagnostic data records The structure and size of vendor-specific diagnostic data records depend on the particular vendor. This information is entered in the GSD file of a device.

Chapter Content This chapter explains the adaptations you will need to make to PC programs if you convert from the PROFIBUS DP to PROFINET IO. The following situations must be distinguished: • whether you previously used the DP base programming interface or • whether you use the OPC interface The steps necessary for migration are described in the following sections for both situations.

6.1
Migration When Using the OPC Interface
Dynamic Response The dynamic response of the PROFINET IO OPC server is the same as that of the PROFIBUS DP OPC server since the OPC interface is a standard interface.
Comparison of the Services The handling of items for services such as Write and Read remains the same. The syntax for calling these services has only slight differences. To migrate comparable services, you therefore only need to replace the items . Table 6-1

Changes in the DP Base User Program Before an existing DP Base user program can be used in PROFINET IO with the IO Base user programming interface, the following modifications are necessary: Table 6-2

Event- or interrupt servicing

Start/stop routines
Must be modified.
Writing User Data (IO data) after Return of a Station or Insert Module Interrupt In PROFIBUS DP, following a station return interrupt or an insert module interrupt, the last data written by the user and its status (GOOD or BAD) is transferred. In PROFINET IO, if the user data has not already been written cyclically, you must make sure yourself that the user data is written again after a station return or insert module interrupt. This data can, for example, be obtained by an initialization routine. As an alternative, the marked "old" data can be written again.
Reference The following sections show where adaptations are necessary in function calls and dynamic sequences.

6.2.2
Comparison of the Dynamic Calls
Semaphores and Callbacks The semaphore mechanism of the DP Base programming interface is no longer supported in the IO Base user programming interface. Alarms and Events are now signaled by callback mechanisms. Since callback mechanisms are asynchronous and can be executed at any time, an IO Base user program must always be prepared for parallel activities. Suitable synchronization mechanisms are therefore necessary.
Hardware Interrupts Fast Logic is not supported.
Process image The difference between a DP Base and IO Base user program when accessing the process image is in the addressing and the access mechanism. Table 6-4

Mechanisms
DP Base user program
IO Base user program
Addressing
Access using the PROFIBUS station number.
Access using addresses assigned during configuration.
Access Mechanism
1. Lock dual-port RAM.
Access to the IO controller using the function calls: • PNIO_data_read • PNIO_data_write
2. Access with pointer to dual-port RAM. 3. Dual-port RAM release.

Contents
Chapter Content If you use certain communications processors (CPs) for Industrial Ethernet, you obtain the functionality of a PROFINET IO controller in your S7 station. • for SIMATIC S7-300: CP 343-1 • for SIMATIC S7-400: CP 443-1 Advanced This section provides with an overview of the interface to PROFINET IO when you use these CPs.
7.2
CP 343-1
Application The CP 343-1 communications processor is intended for use in an S7-300 programmable controller. It allows attachment of the S7-300 to Industrial Ethernet. With the services for PROFINET IO, the CP 343-1 allows direct access to PROFINET IO devices over Industrial Ethernet
FCs in the User Program Just as for the CPs for PROFIBUS DP, special FCs are also available for PROFINET IO: • FC9 (PNIO_SEND) • FC10 (PNIO_RECV) • FC11 (PNIO_ADDR)
Further information For a detailed description of the functions, refer to the S7-CPs for Industrial Ethernet Configuration and Commissioning manual and the STEP 7 online help. For information on using the CP and the maximum configurations with the PROFINET IO interface, refer to the device documentation supplied with the CP on the SIMATIC NET Manual Collection CD.
