Page 16: Operating Environment Precautions
Operating Environment Precautions • The PLC outputs may remain ON or OFF due to deposits on or burning of the output relays, or destruction of the output transistors. As a counter- measure for such problems, external safety measures must be provided to ensure safety in the system. -
Page 17: Application Precautions
• When adding a new device to the network, make sure that the baud rate is the same as other stations. • When adding a new SmartSlice I/O Unit to the Communication Unit, make sure that the GRT1-PRT PROFIBUS Communication Unit is powered down, to prevent unexpected results when starting up the new station. -
Page 18: Conformance To Ec Directives
Conformance to EC Directives • Take appropriate measures to prevent foreign objects from entering the unit when mounting or wiring it. Failure to do so, may result in unit dam- age, electric shock or fire. • Use crimp terminals for wiring. Do not connect bare stranded wires directly to terminals. -
Page 19: Conformance To Ec Directives
PROFIBUS units should be installed as follows, for the complete configuration to meet the EC directives: 1,2,3... 1. The units are designed for installation inside control panels. All units must be installed within control panels. 2. Use reinforced insulation or double insulation for the DC power supplies used for the communication power supply, internal circuit power supply, and the I/O power supplies. -

It can also save the settings, using the features of the FDT Con- tainer program. - Page 27 The drawback of the GSD file is that- unlike the GRT1-PRT DTM - it only pro- vides setting options for PROFIBUS DP and PROFIBUS DP-V1. The GSD file does not provide the means to initiate parameter data transfer via PROFIBUS DP-V1 Class 2 messages.

3-1-3 SmartSlice I/O Allocation to the GRT1-PRT Unit The SmartSlice I/O Units’ I/O data is mapped in the I/O memory of the GRT1- PRT, from which it is transferred to the PROFIBUS Master unit. This allocation is done automatically and determined by the SmartSlice I/O Unit’s type. The figure below shows this mapping. - Page 53 5. Word sized SmartSlice I/O Units, e.g. GRT1-AD2, GRT1-DA2V are mapped to one or more words. 6. Total size of mapped I/O data can be 64 words output and 64 words input.

SmartSlice I/O Units’ power supply is ON. The registered table is enabled if DIP switch 1 is ON when the power is turned ON. If DIP switch 1 is OFF when the power is turned ON, the registered table is disabled and the Com- munication Unit will automatically detect the actual I/O configuration and start communication. - Page 56 Unit Functions Section 3-2 Comparison with the When DIP switch pin 1 (REGS) is ON and an I/O configuration table has been Registered Table registered in the Communication Unit, the actual I/O configuration is automat- ically compared to the registered table when the power is turned ON.

4. Only replace one I/O Unit at a time. 5. Always replace the I/O Unit with the same model of I/O Unit. If a Unit is re- placed with a different model, there may be unexpected outputs and the re- store operation may not be completed properly. -
Page 60: I/O Communication Error History Monitor
The PROFIBUS Communication Unit can record the 64 most recent internal SmartSlice Communication Unit errors in the Unit’s error history. When more than 64 errors occur, the oldest entry is deleted to make space for the newest error entry. The communication error history can be read from the GRT1-PRT DTM or via messaging services. -

Page 90: Profibus Technology
In general, the PROFIBUS communication protocol is based on the Open System Interconnection (OSI) refer- ence model in accordance with the international standard ISO-7498 (see the following illustration). The model defines 7 layers of communication functions, three of which - layers 1, 2, and 7 - are used in PROFIBUS. DP-Profiles... - Page 91 Appendix A PROFIBUS Technology PROFIBUS DP uses layers 1 and 2, and the user interface. Layers 3 to 7 are not defined for PROFIBUS DP. The User Interface Layer defines the interface functions for specific application areas, i.e. the PROFIBUS DP basic functions and communication profiles.
- Page 92 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. Each master executes this procedure automatically.
- Page 93 CLEAR state. Slave devices use a watchdog to detect failures of the master or the bus. If no data exchange with the master occurs within the set watchdog time interval, the slave automatically switches its outputs to the fail-safe mode.
- Page 94 When comparing the two configuration technologies, a GSD file only provides information on the device char- acteristics and configuration options. It has no GUI of its own, nor can it connect to the device itself. A GSD file always requires a separate configurator program to interpret the data. In the FDT/DTM concept all these device related functions are included in the DTM.

Page 96: Slave Diagnostics Message
Description Diag.Station_Non_Existent This bit is set by the Master Unit if the Unit does not respond to any of the request messages sent by the master. If this bit is set the diagnostic bits contains the state of the last diagnostic message or the initial value. The slave device sets this bit to zero in case of a correct response. - Page 97 Master Unit receives more diagnostic information than it can enter in its diag- nostic buffer. Slave Diagnostics Byte 4: Master PROFIBUS Address This byte contains the PROFIBUS address of the Master Unit, which parameterized the slave. If the slave is not parameterized correctly, the byte contains FF (Hex) or 255 (Decimal).
