Chapter 1 Overview You have just purchased the most ad vanced load monitoring solution available. HELM INSTRUMENT COMPANY, INC. manufactures a complete line of load monitorin g control solutions for use on metal stamping, forging, compaction and asse mb ly presses; cold forming, cold heating, injection molding and die cast machi nes.
Chapter 1 Hardware Overview The Weigh Scale m odule can be attached to the controller or to an adjacent I/O module before or after din rail mounting. It is a Class 1 module (uses eight input words and eight output words). It interfaces to strain gage based transdu cers (350ohm or 700ohm).
Chapter 2 Getting Started This chapter can help you to get started using the Helm Weigh Scale module. The procedures i ncluded here assume that you have a basic understanding of PLC products.
Chapter 2 System Operation The Weigh Scale module communicates to the processor through the p arallel backplane interface and receives +5Vdc and +24V dc power from the power supply through the backplane. No exte rnal power su pply is required. The MicroLogix and CompactL ogix platforms can support up to 8 I/O modules.
Chapter 3 Channel Configuration Data and Status This chapter explains how the Weig h Scale module and the proces sor communicate through the module's input and output image. For CompactLogix / RSLogix ™ 5000 setup, plea se refer to Appen dix A With RS Logix500 software, ve rify the module ID code.
Chapter 3 Output Image (cont.) Zero Stabilize Bit (O:e/3) Enables module feature to display “0” when Weigh scale is empty. 0 = Disable 1 = Enable Least Significant Bit (LSD) Flicke r Bi t (O:e/4) LSD of weigh value. Does not change when load is applied or if load is constant.
Chapter 3 The 8-word module input image (input from the module to the CPU) represents data words and status words. I nput words (data words) hold t he input data that represents the values of the sensor inputs.
Chapter 3 Input Image (cont.) Channel 1 Weigh Value (I:e.1) Weigh value for Channel 1 Channel 2 Weigh Value (I:e.2) Weigh value for Channel 2. Channel 1 A/D Trim Value (I:e.3) Value stored in module for Channel 1. Value should match value on sticke r.
Chapter 3 Integer File Using RS Logix500 software, rese rve an in teger file for Weigh Module monitoring. For illustration purposes in this manual, we have reserved Integer file N10:0 - N10:16.
Chapter 4 Setup Procedure A complete listing of a sample ladder logic program is included at the back of this ma nual. Examples shown here are for reference.
