Section 1: Overview Section 1 OVERVIEW 1.1. SCOPE This manual describes the operating procedures, specifications, installation, and setup for the Hardy Process Solutions, PROFIBUS Interface Option -B12, which is used with the Hardy HI 2151 Series Weight Controllers. To ensure the maximum service life and safe operation of the PROFIBUS Interface Card, use the card only as described in this manual and observe the cautions, warnings, and safety procedures. Hardy Process Solutions appreciates your business.
HI 2151 Series Weight Controller Profibus Interface Option 1.5. PROFIBUS-DP CAPABILITIES 1.5.1 Watch Dog Watch Dog communication control detects failures in the bus or the assigned DPM1 (DPMaster - Class 1, which is the central controller in PROFIBUS-DP). If the interface card detects no successful data transfers within a set interval, it switches its outputs to the failsafe state until successful communication is resumed. 1.5.
Section 1: Overview 1.5.5 BAUD RATE AUTO-DETECT The PROFIBUS network can support up to 12 Mbaud transfer rates. The server’s Auto Detect function finds the system baud rate (the rate of the slowest component), which eliminates the need for board settings. 1.5.6 MULTIPLE NODES Depending on the PLC, the PROFIBUS network is configurable to include several nodes (The HI 2151 weight controller is one node) up to a maximum of 126. 1.5.7 GSD FILE Some PLC’s require the GSD file (HRDY2151.

Humidity: 0 to 80% Relative Humidity (Non-condensing) Baud Rate 9,600 kbaud to 12 Mbaud - (Auto-Selectable) Process Control Standards Reference Process Fieldbus (PROFIBUS) - DIN 19 245 Reference Data Protocols Master manuals will reference data either in bytes or words using the different protocols that are particular to a server or series of servers. For example: 1.
Section 2: Installation SECTION 2 INSTALLATION 2.1. SCOPE Chapter 2 explains unpacking, cabling and interconnection, and installation of the -B12 PROFIBUS Interface Card. Operators and maintenance personnel should read the procedures in this chapter before installing or operating the PROFIBUS interface card. 2.2 UNPACKING 1. Inspect the packing for damage of any kind, before signing for or opening the package. 2. Report any damage to the carrier company immediately. 3.
HI 2151 Series Weight Controller Profibus Interface Option B. Panel Mount, Remote, and Blind Installations. Remove the four Phillips head machine screws that fasten the chassis to the HI 2151 Series WC cover. Figure 2-2 6 3. Pull the chassis completely out of the cover. 4. Place the chassis on an anti-static pad. 5. Put on an anti-static wristlet and connect it to the anti-static pad. 6. Analog to Digital PCB is clearly visible and there are eight standoffs mounted on the board. (See Fig.
Section 2: Installation Figure 2-3 8. On the solder side of the PROFIBUS Interface Card, the side opposite the components, there is a pin connector. (See Fig. 2-3) Figure 2-4 9. With the pin connector side down, carefully plug the PROFIBUS Interface Card into either connector J4 or J5 (See Fig. 2-2) whichever is available. These connectors also refer to option 1 or option 2 on the rear panel. Option 1 uses connector J5. Option 2 uses connector J4. (See Fig.
HI 2151 Series Weight Controller Profibus Interface Option 10. The through holes on the PROFIBUS Interface Card should line up with the threaded holes in the standoffs. A little adjustment is sometimes necessary to line them up. (See Fig. 2-5) Figure 2-5 11. Place the washers over the holes on the component side of the PROFIBUS Interface Card and install the four Phillips pan head SEM screws (See Fig. 2-5).

HI 2151 Series Weight Controller Profibus Interface Option 2.7 COMMUNICATION RATE/CABLE LENGTHS/CONNECTORS Shielded twisted pair two wire cable is required for the PROFIBUS Interface Connection. The characteristic impedance of the cable should be in the range between 135 and 165 Ohms (3 to 20 MHZ), the cable capacity (conductor-conductor) should be <30 pF/M and the conductor area should be 0,34 mm2. The 9 pin din connector on the option board is used for all PROFIBUS connections.
Section 3: Setup SECTION 3 SETUP 3.1 SCOPE Chapter 3 consists of all the procedures to setup the PROFIBUS Interface Option. To make sure that the interface option works properly, programmers and maintenance personnel should be familiar with this chapter before setting up or operating the system. 3.2 PANEL, WALL AND REMOTE SETUP PROCEDURE 1. Press the 7/Option button. (See Fig. 3-1) The first option appears. Figure 3-1 NOTE: 2. Press the “4/Up” ( 3. Press the “Enter” button.
HI 2151 Series Weight Controller Profibus Interface Option Figure 3-2 6. NOTE: Press the Test/Clr button. The display should now show four “0's”. (See Fig. 3-3) On an uncleared display, numbers are added to the right of the existing number. Figure 3-3 7. Use the keypad to enter the new number. 8. Press the “Enter” button to set the address. 9. Exit the Options Menu by pressing the “Exit” button. 1.
Section 3: Setup 3.3 BLIND UNIT SETUP PROCEDURE A blind HI 2151 Series Weight Controller is configured without a front panel and keypad. To set the PROFIBUS station address, a dip switch on the PROFIBUS Interface Card and the Power & Relay PCB, must be set. To set the power and relay (Prt # 0535-0427) dipswitches for the PROFIBUS Interface Card: 1. Disconnect the power cord. 2. Open the panel door. 3. On the Power & Relay Printed Circuit Board (Prt # 0535-0427) there is a dipswitch S2. (See Fig.
HI 2151 Series Weight Controller Profibus Interface Option 3.3.1 1. SETTING THE ADDRESS FOR BLIND UNITS The Dipswitches on the PROFIBUS Interface Card represent a binary value as follows: Switch 1 2 3 4 5 6 7 8 NOTE: Binary Value 1 2 4 8 16 32 64 Not used 2. A PROFIBUS address can have a binary value from 1 to 125. 3. To set the address move the dipswitches that total the address binary number to the “on” position.

HI 2151 Series Weight Controller Profibus Interface Option NOTE: 3. 8.5 Sending another command with valid parameters will correct the error. However, to clear the response/error code bits you must rerun the write “0" or “90" command, which clears the response/error code bits. Otherwise the error bit will always reflect the previous error. To check if the associated bit(s) have been cleared. Read the response/error bits to see if they are zero.
