Assumption of Explanation The explanation in this manual assumes that the DX is connected via communications with Programmable Logic Controller (PLC). For information on how to operate PLCs, see the user's manual of respective products. This manual is intended for those who have used an PROFIBUS-DP. In this manual, the screens of the DX1000 are used. The content displayed on the DX2000 screens are not different from those displayed on the DX1000 screen.

Introduction of Features PROFIBUS-DP PROFIBUS is an open field bus standard (IEC61158) used in various applications for factory automation and process automation. PROFIBUS-DP (Decentralized Periphery) is used for communication between PLCs and remote I/O, enabling high-speed data transmission. Configuration Components PROFIBUS-DP network consists of following components: • Class 1 master A controller to exchange information with the slave in a cyclic manner. This is a PLC or PC.
Introduction of Features What the DX Can Do The DX provides the following functions: • Participate in an PROFIBUS-DP network as a PROFIBUS-DP slave. • Communicate with a PLC from Siemens. • The master can access internal data of the DX. Data Access Measurement channel data Read Computation channel*1 data Read Communication input data*1*2 Write *1 This is an option (/M1 and /PM1). *2 Communication input data, if coded in a calculation expression in the computation channel, can be displayed on the DX.
Connection to the PROFIBUS-DP Network Cable Connection Connect the PROFIBUS-DP cable to a PROFIBUS-DP connector provided on the back of the DX. 5 4 3 2 1 (Rear panel) 9 8 7 6 Connector D-sub 9-pin (female) connector. Each pin corresponds to the following signals. Pin Signal name 3 RxD/TxD - P 4 CNTR - P 5 DGND 6 VP + 5 V 8 RxD/TxD - N Pins 1, 2, 7, and 9 are not used. Explanation Positive data receive/transmit. RTS (for use by repeater). Ground. + 5 V. Negative data receive/transmit.
Connection to the PROFIBUS-DP Network Settings of the DX Node Address Settings Press MENU (to switch to setting mode), hold down FUNC for 3 s (to switch to basic setting mode), and select the Menu tab > Communication (PROFIBUS). • Node Address Set a node address in the range of 0 to 125. Note The node address of PROFIBUS-DP can be checked on the Network Information Screen of the DX. You can open the Network Information Screen by pressing FUNC > Network info softkey.
Preparation for PLC GSD File Installation To have the DX participate in a network, you must first install the DX device database file (GSD file) in the configuration tool. A PLC communicates with the DX based on the information in the GSD file. For information on using the configuration tool, see the configuration tool user's manual. PROFIBUS configuration tool PLC PROFIBU-DP GSD file DX How to Obtain the GSD File Obtain the GSD file from the Yokogawa Web site: URL: www.yokogawa.
Preparation for PLC Specification of Data If you install the GSD file, the DX is added to the configuration tool as a "General" type "Slave". Select [Model] to expand the module list and select your DX model from the list.
I/O Buffer and Data Mapping A master device such as a PLC accesses internal data of the DX via the "Input buffer" and "Output buffer" of the DX. "Input" represents an input to the master, while "Output" represents an output from the master. Mapping Method of the I/O buffer The "Input buffer" and "Output buffer" of the DX for PROFIBUS-DP communication has 128 bytes each. Data is laid out as described in the following table. Data layout cannot be changed.
I/O Buffer and Data Mapping Data Mapping Data mapping for each model is shown in the table. The following symbols are used in the table. Symbol Explanation CH1, CH2 Data of the measurement channel 1 or measurement channel 2. CH101, CH112 Data of the computation channel 101 or computation channel 112. C01, C24 Communication input data. INT16 16-bit signed integer. INT32_B 32-bit signed integer, BigEndian*. * BigEndian: Assuming that a value of 01020304H is located as 01 02 03 04 in the buffer.
