  • Page 7: Introduction

    This manual is intended for use by service technicians responsible for installing and servicing 720i digital weight indicators. This manual applies to Version 2.00 of the 720i indicator software and Version 1.01 of the 720i batching indicator software. Configuration and calibration of the indicator can be accomplished using the Revolution configuration utility, serial commands or the indicator front panel keys.

  • Page 8: Overview

    720i Programmable Weight Indicator/Controller Overview The 720i is a single-channel programmable digital weight indicator/controller. The 720i can be loaded with PCE software or 720i batching software. Refer to Section 9.0 on page 79 Section 10.0 on page 95 for further information on software choices.

  • Page 9: System Configurations

    System Configurations All models include a CPU board with one option card slot. The 720i is a single scale unit and cannot be upgraded to a multi- channel A/D. The 720 is provided with either the PCE firmware, which includes Truck In/Out programs or as Batching firmware for setpoint control.

  • Page 10: Operation

    720i Programmable Weight Indicator/Controller Operation This section provides an overview of 720i Programmable HMI Indicator/Controller operation instructions. The 720i universal model front panel consists of a 22-button keypad with an LCD display (Figure 2-1). The keys are grouped as four configurable softkeys, four scale function/navigation keys, Menu and Print/Enter keys, and numeric entry keys. The panel mount front panel consists of a 10-button keypad with an LCD display.

Bits 1 and 2 in the Digital I/O menu (Section 4.5.9 on page 62) are assigned to Batch Start and Batch Run functions.

  • Page 95: Using Proaction Pcee

    NOTE: When working with this chapter, the PCE Version software must be installed. In addition to Revolution, the 720i is supported by two additional applications that extend its capabilities for batch control and database management. ProAction PCEE, or Process Control Engine Editor, provides functions similar to setpoint configuration for 720i-based batch control.

    10.4 Revolution Whenever a PCE process is built, be sure to build a Revolution hardware configuration file using the 720i module so that all configuration parameters match the process. The Revolution file defines the required digital i/o, softkeys, and the print formats (AuxFmt) used.

    For ease in the debugging process, there is an EDP command that dumps the raw list of commands which have been sent to the 720i, "SPSUMP." The first half of the list is all the conditions and actions. The second half lists the steps and associated conditions and actions by numeric reference.

    The <USx> strings can be added to all formats and there are 99 of these to use. A Set User Print Text fills these fields. They are strings but all types of data, (real, integer, string or DT) can be inserted and the 720i converts it to a printable string.

  • Page 100: Serial Commands

    Serial Commands The 720i indicator can be controlled by a personal computer or remote keyboard connected to an indicator serial port. Control is provided by a set of serial commands that can simulate front panel key press functions, display and change setup parameters, and perform reporting functions.

  • Page 117: Serial Scale Interface

    Serial port 4 or the expansion port can be configured for serial scale input. The serial scale function allows other scale indicators to send gross, net, or tare weight data to the 720i. Once a serial port has been configured to accept scale data, the data format can be customized to match the data stream sent by that indicator.
