1. Introduction

Manual updates

This manual is updated for the 101.1.0.0 program version. In this program is a web server added which enables for the user to access the instrument using a PC running a web browser. This manual can also be used for the previous program version (101.0.0.0) where the only differences are the ‘Network Config.’ menu, the Instrument restart functionality and the remote access part.

General

The G4 Instrument is a high performance multi channel force indicator intended for industrial systems. Its basic function is to convert the signals from strain gauge transducers to useful force information. Transducer excitation is included as well as parameter controlled signal processing, indication of output levels, error supervision and operation of optional external equipment. The instrument can be equipped with up to 6 synchronized force channels.

The instrument is modular and can be equipped with different types of I/O units to match the demands in the specific applications. There are strain gauge transducer interface modules, a digital input/output module, analog output modules. Internal solid-state outputs in the instrument can be used for output functions from level supervision or ‘In process’ indication, reporting the operating status of the G4 Instrument.

The CPU unit in the instrument has several communication interfaces. It has two serial communication ports, an Ethernet port, an USB port and a fieldbus slot. Several G4 Instruments can be controlled from a master computer or PLC. Serial communication interfaces are RS-485 and RS-232 using Modbus RTU protocol. The Ethernet interface is using Modbus TCP and the optional fieldbus interface uses Profibus or DeviceNet.

It is possible to load new software into the instrument using the USB port. All functions in the G4 Instrument are controlled by set-up parameters. Setting of

parameter values can be performed via a service panel with display and 4 keys (VIEWPAN module).

The Rail mount instrument type is powered with 24 V DC. All input and output signals are galvanically isolated from the power supply by operational insulation.

Functions

Measurement with strain gauge transducers.

Both excitation voltage and output signal are measured at the transducer to avoid influence from voltage drop in the connection cable. Excitation to the transducer, from the G4 Instrument is provided over separate wires. A shielded 6-wire cable must be used to connect a distant transducer to the instrument.

A/D conversion. The analog signals from the transducer are converted to digital form and filtered to give an internal transducer signal with high resolution.

Calculation. The transducer excitation and signal values are combined to form an internal transducer signal, representing the load on the transducer. Influenced by calibration data, this signal is converted to a digital measurement value, the force value, which can be presented at the local display window and at external equipment.

Error supervision. As long as the error supervision detects no error, the signal ‘In process’ is present but if an error is detected, ‘In process’ will be off and a specific error message will be displayed. ‘In process’ can be set to control any digital output. Note that there are force channel specific and instrument specific error detection.

Levels. 32 level comparators in the instrument can be set to switch at defined signal levels with any selected hysteresis added, meaning that the switch level can be different for increasing and decreasing signal. It’s possible to set level switching delays. Output signals from these comparators are available on the serial communication. The level comparator outputs can also be set to control digital outputs from the instrument.

Communication. The G4 Instrument utilizes the serial interface, Ethernet and a fieldbus interface for communication with control computer. The serial interface consists of a RS-232 (COM1) connection and a RS-485/RS-422 (COM2) connection. COM2 can be used with 2- or 4-wire connection. Force values, web tension values, level status, error status etc. can be collected and commands given through the communication interfaces. Modbus RTU protocol is used for the serial interfaces and Modbus TCP for the Ethernet connection. For the optional fieldbus interface Profibus or DeviceNet can be used.

Instrument modes.

In normal operation mode the G4 Instrument is presenting the measurement values on the front panel (VIEWPAN) alphanumerical display. Values for one Function Block at a time can be shown. During parameter set-up the instrument will continue normal operation. However if hardware set-up parameters have been changed the instrument will be restarted. The operator will always be notified before the instrument is restarted.

Parameter setting.

In the instrument all operating functions are controlled by set-up parameters with numerical values, string values, or pre-selected values from a list of alternatives. Parameter set-up is performed by the keys at the service panel (VIEWPAN).

Presentation.

The instrument can present measured or calculated values, parameter settings etc. at the front panel. An extensive system of menus gives the possibility to present various information about the instrument. The VIEWPAN module can present one or two values at a time.

Measured or calculated values, status of levels and so on, can be transferred to external equipment via the different communication interfaces (some are optional).

earth via cable shield filters according to the Profibus standard.

For connection of the adaptor to the Profibus master, use a Profibus standard cable and connector according to the diagram below.

For reliable fieldbus function, line termination must be arranged in both ends of the transmission line. For a G4 instrument, at the end of the cable, a connector with line termination should be used. For all other G4 Instruments connection without line termination should be used.

For configuration of the adaptor, a GSD file (VISH0AB3.GSD) is available and should be installed in the master.
