3. ABOUT PROFIBUS PA 3. ABOUT PROFIBUS PA 3.1 Outline 3.4 Wiring System Configuration PROFIBUS PA is a widely used bi-directional digital communication protocol that enables the implementation of technologically advanced process control systems. The EJA Series PROFIBUS PA communication type meets the specifications of PROFIBUS Nutzerorganisation e.V. and is interoperable with devices from Yokogawa and other manufacturers.
4. GETTING STARTED 4. GETTING STARTED PROFIBUS PA is fully dependent upon digital communication protocol and differs in operation from conventional 4 to 20 mA transmission and the BRAIN communication protocol. HMI Class 2 Master FieldMate (FDT/DTM) PDM (EDDL), etc. • DP/PA Couplers: PROFIBUS PA requires DP/PA couplers which convert the RS-485 signals to the IEC 61158-2 signal level and power the field devices via the PROFIBUS PA. • Cable: Refer to Figure 4.1. Table 4.
4. GETTING STARTED 4.2 Master Settings 4.3 Integration of GSD To activate PROFIBUS PA, the following bus parameters must be set for the master. A PROFIBUS PA system requires a GSD file containing device parameters such as the supported transmission rate, input data, output data, data format and data length. The following GSD files are available for the EJA. Table 4.
4. GETTING STARTED 4.4 Engineering Tools 4.4.2 SIMATIC PDM for EDDL Engineering of the EJA PROFIBUS PA can be performed with the following two tools. Electronic Device Description Language (EDDL) defines field device information, and can be used independently of vendors. EDDL files can be read by engineering tools, and the software is used to conduct adjustment, configuration, calibration and tests of devices. 4.4.

5. CONFIGURATION 5. CONFIGURATION This chapter describes the basic parameters for the three block types and explains how to set and change these parameters. 5.1 Description of Basic Parameters 5.1.1 Physical Block Parameters Physical Block Identification TAG Descriptor Device Serial Number Serial Number Target Mode Diagnosis Diagnosis Diagnosis Extension Write Locking F0501.EPS Figure 5.
5. CONFIGURATION Target Mode: Indicates the AI block mode: Out of Service (O/S), MAN, or AUTO. Target Mode indicates what mode of operation is desired for the AI block. In Out of Service mode, the AI block does not operate. Manual mode does not allow values to be updated. AUTO mode causes the measured values to be updated. Under normal circumstance, set this to AUTO mode. AUTO mode is the factory default.
5. CONFIGURATION Pressure Raw Value Unit: This contains the pressure unit for the calibration values. Temperature Unit: This contains the units of the sensor temperature. Pressure Raw Value: This contains the calibrated sensor value. The unit is derived from pressure raw value unit. Sensor Upper/Lower Limit: These contain the sensor upper/lower limit value. The unit is derived from pressure raw value unit. Upper/Lower Calibration Point: These contain the highest/lowest calibrated value.

CONFIGURATION 5.2 Basic Parameter Setting and Changing Table 5.2 Navigation tree structure of online parameters Level of node 1st Process Variable Device Status Diag and Service Easy Setup Calibration Physical Block This section describes basic parameter setting and changing with FieldMate. For detailed information on FieldMate, refer to FieldMate User’s manual. Input Identification Diagnosis Configuration Transducer Block Output Analog Input 1 5.2.
5. CONFIGURATION Example of DTM context screen (a) Process Variables 5.3 Bus Address Setup Every device in PROFIBUS must be assigned a unique address in the range of 0 to 126. If it is not specified at the time of order, ‘126’ is the factory default. Do not change to ‘0’,’1’ or ‘2’ as these are used by master devices. Note: This function is only available if an offline connection to the device is selected.
5. CONFIGURATION Enter [Old Address] to 5 and [New Address] to 20 and Click [Set] Table 5.4 Operation Mode AI Block Automatic (AUTO) Yes Manual (MAN) Yes Out of Service (O/S) Yes “New address successfully set” is displayed in the State field.

LIST OF PARAMETERS FOR EACH BLOCK OF THE EJA” for details of the Write Mode for each block. 5.4.1 Tag Number (TAG) Enter the Tag number in TAG.
5. CONFIGURATION Select the desired pressure unit. 5.4.5 Output Scale (Out Scale) and Unit Press the Enter key to confirm the data. Change the Target Mode of Analog Input1 to Out of Service (O/S). AL.23 occurs when the Target Mode is changed to Out of Service (O/S). Select the unit for Out Scale Unit, and press the Enter key to confirm the data. Enter the values configured in Out Scale (Upper/Lower Value), and press the Enter key to confirm the data.
5. CONFIGURATION 5.6 Output Analog Input 1 Setup In the DTM Works window, double-click the [Output] folder. Click the [Analog Input 1] folder. 5.6.1 Fail Safe Mode Fail Safe Mode defines the Output Value and Status (Quality) if a device breaks down. Select Fail Safe Mode, and press the Enter key to confirm the data. When selecting “Default Value is used as Output Value”, enter the desired values for the Fail Safe Default, and press the Enter key to confirm the data. Table 5.
6. CALIBRATION 6. CALIBRATION 6.1 Zero-point adjustment Zero-point adjustment can be performed in two ways. Choose the optimum method in accordance with the circumstances specific to the application employed. The amount of zero-point adjustment changes according to the speed at which the zero-point screw is turned; turn it slowly for fine tuning, or quickly for rough tuning. 6.
7. IN-PROCESS OPERATION 7. IN-PROCESS OPERATION This chapter describes the in-process operation of the EJA 7.1 Mode Transition When each block mode is changed to Out of Service (O/S), the block pauses and a block alarm is issued. When the AI block mode is changed to MAN, the AI block suspends updating of output values. In this case alone, it is possible to write a value and status to the OUT parameter of the block for output. 7.2 Generation of Alarms 7.2.
7. IN-PROCESS OPERATION 7.2.2 Status of Each Parameter in Failure Mode The DTM and EDDL messages when the LCD indicates an alarm are listed in the following table.
