Page 16: Precautions
PRECAUTIONS This section provides general precautions for using the PROFIBUS Master Units, Programmable Controllers and related devices. The information contained in this section is important for the safe and reliable operation of the PROFIBUS Master Units. You must read this section and understand the information contained before attempting to set up or operate a PROFIBUS Master Unit and PLC system.
Page 17: Intended Audience
It is extremely important that all PLC Units be used for their specified pur- poses and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult your OMRON repre- sentative before using a PLC System in the above-mentioned applications.
Page 18: Operating Environment Precautions
Operating Environment Precautions !WARNING The CPU Unit refreshes I/O even when the program is stopped (i.e., even in PROGRAM mode). Confirm safety thoroughly in advance before changing the status of any part of memory allocated to I/O Units, Special I/O Units, or CPU Bus Units.
Page 19: Application Precautions
Application Precautions Application Precautions Observe the following precautions when using the PROFIBUS Master Unit. !WARNING Failure to abide by the following precautions could lead to serious or possibly fatal injury. Always heed these precautions. Ω • Always connect to a class-3 ground (100 or less) when installing the Units.
Page 20 Application Precautions • Observe the following precautions when wiring the communications cable. • Separate the communications cables from the power lines or high-ten- sion lines. • Do not bend the communications cables. • Do not pull on the communications cables. •...
Page 21: Conformance To Ec Directives
EMC-related performance of OMRON Units complying with EC Directives will vary depending on the configuration, wiring, and other conditions of the equip- ment or control panel in which OMRON devices are installed. The customer must, therefore, perform final checks to confirm that units and the overall sys- tem conforms to EMC standards.
Page 22: Features And Specifications
SECTION 1 Features and Specifications This section provides an introductory overview of PROFIBUS, its functions and how to setup and configure a network. It also addresses the PROFIBUS Master Units and the configurator, their features and specifications. Overview of PROFIBUS ......... 1-1-1 Introduction.
Page 23: Overview Of Profibus
Overview of PROFIBUS Section 1-1 Overview of PROFIBUS 1-1-1 Introduction Standard EN50170 PROFIBUS (PROcess FIeldBUS) is an open fieldbus standard for a wide range of applications in manufacturing, processing and building automation. The Standard, EN 50170 (the Euronorm for field communications), to which PROFIBUS adheres, guarantees vendor independence and transparency of operation.

Page 25: Device Types
Overview of PROFIBUS Section 1-1 1-1-3 Device Types PROFIBUS distinguishes between master devices and slave devices. Master Devices Master devices determine the data communication on the bus. A Master can send messages without an external request, as long as it holds the bus access right (the token).
Page 26: Diagnostic Functions
Overview of PROFIBUS Section 1-1 Token Passing The token passing procedure guarantees that the bus access right (the token) is assigned to each master within a precisely defined time frame. The token message, a special message for passing access rights from one master to the next master, must be passed around the logical token ring - once to each master - within a specified target rotation time.
Page 27: Protection Mechanisms
Overview of PROFIBUS Section 1-1 1-1-6 Protection Mechanisms Monitoring Time PROFIBUS DP provides effective protection functions against parameteriza- tion errors or failure of the transmission equipment. Time monitoring is pro- vided both at the master and the slave devices. The monitoring interval is specified when the system is configured.

Page 199: Plc Cycle Time Performance
I/O Communication Characteristics Section 6-5 6-5-5 PLC Cycle Time Performance The cyclic refresh time is the time required for I/O data to be exchanged between the PLC CPU Unit and the PROFIBUS Master Unit. The PLC CPU Unit cyclic refresh time is increased when a PROFIBUS Master Unit is mounted, as shown below.

Page 203: Operating The Network
Operating the Network Section 6-6 Operating the Network 6-6-1 User Access to the Network There are several ways through which a user can have access to and control over the PROFIBUS network. • Through a PLC user program A PLC user program can set the operational mode of the Unit, send Glo- bal-Control commands, read Master and slave status / diagnostics infor- mation, and access the Unit’s Error Log.
Page 204: Changing Profibus Mode Of The Master Unit
Operating the Network Section 6-6 6-6-2 Changing PROFIBUS Mode of the Master Unit PROFIBUS DP Network The PROFIBUS standard defines four different network modes, in which a Modes Master Unit can operate. The modes are: • OFFLINE The PROFIBUS Master Unit does not access the network, nor does it respond to messages.
Page 205 Operating the Network Section 6-6 Example Below is an example ladder program, which changes the operational mode to OPERATE, if the current mode is not OPERATE and non of the other mode switches are set. The unit number for the example Unit is 0. A200.11 000000 (000000)
Page 206: Transmitting Global-Control Commands
Operating the Network Section 6-6 6-6-3 Transmitting Global-Control Commands Global-Control commands The CS1/CJ1W-PRM21 PROFIBUS Master Units support the transmission of Global-Control commands. These messages are unconfirmed broadcast messages (i.e. the slave devices do not send a response message), which can be used to synchronize I/O data related events two more slave devices. I/O Data Synchronization Two types of synchronization can be achieved.

Page 208 Operating the Network Section 6-6 Note If a Global-Control command contains both a Sync and an Unsync command, the Unsync will prevail. The figure shown below illustrates the Sync / Unsync feature as implemented by the CS1/CJ1W-PRM21 PROFIBUS Master Unit. Global-Control Sync command Global-Control Unsync command Instruction...

The slave device will set this bit to 0. Diag.Prm_Fault Set by the slave device, this bit indicates that the last received parameter data from the Master Unit have been rejected.
Page 257 Appendix B Slave Diagnostics Message Name Description Reserved These bits are reserved and always set to 0 by the slave device. Diag.Ext_Diag_Overflow If set, this bit indicates that there exists more diagnostic information than speci- fied in Ext_Diag_Data. This bit will - for example - be set if the slave device has more diagnostics available than it can enter in its send buffer.

The Device diagnostics will follow this header byte. Maximum length of the block, including the header is 63 bytes. Interpretation of the diagnostics bytes in this block is device dependent.
