Backwards compatibility and legacy interfacing

This interface is supported on the PGC5000 Direct Modbus

TCP from the VistaGateway Modbus Client application, and

OPC server application. If you use a VistaGateway, you only

have to write to one set of registers or OPC tag. If you are

writing direct to the PGC5000 then you must write to each

PGC5000’s Modbus interface because each PGC5000 acts

as a Modbus slave.

If you have legacy instruments (such as the model 3100 or

PGC2000 Series) then you must use a VistaGateway or a

Modbus enabled router. However, the Modbus enabled router

does not support the PGC5000 but you can write through the

Modbus enabled router to the PGC5000 using the Ethernet

switch with the PGC5000 being the actual Modbus slave.

Time Synchronization in the current data system

Time synchronization is supported in the PGC5000 with

Version 3.0.3.12 and later software.

This feature can be implemented either through a Modbus link

direct from the PGC5000 (acting as a Modbus Slave), or from

a connection to the VistaGateway either using an OPC

connection or a Modbus connection.

With an OPC connection, the tag that is connected and

written to by an OPC Client is the following.

Note: OPC connection not available direct from PGC5000.

SetAnalyzerDate

This is a Canonical Date Type 7 (i.e. DATE).

With a Modbus master connection, the time is set by

adding the following entry to the Modbus Map.

Analyzername.SetAnalyzerClock,1.40001.DATE,

This will then reserve 7 registers in the following order.

40001 Hour

40002 Minute

40003 Second

40004 Day of month

40005 Month

40006 Year

40007 Day of week

The time and date information must be written starting with

hour and finished with the day of the week register. The latter

will trigger the setting of time.

The STAR Server is an appliance server that saves data

from PGC5000 (Version 4), PGC2000. RVP, and Multiwave.

The STAR Server has three different licensing levels 1-5.

1-15. 1-250. If the 1-250 level is purchased, a 12 Terabyte

hard drive array is supplied in order to guarantee maximum

system availability.

Measurement made easy

VistaSTAR is the next generation of data system interface

software designed to unify the legacy generation

instrumentation that we have in the field with the current

PGC5000 Series of instrumentation for a complete analyzer

asset optimization and plant monitoring tool. VistaSTAR data

system uses many of the existing instrumentation and

applications found in VistaNET. VistaSTAR introduces two

additional applications; the STAR Client and the STAR Server,

and adds several new features to our flagship Process Gas

Chromatograph – PGC5000 Version 4.

The STAR Client is a windows based application that provides

a centralized launch point for the legacy VistaNET applications

and current versions of Remote Client. It also allows the user

to view trends and chromatograms that are historized in the

STAR Server.

ATEX Directive 2014/34/EU, annex II

The PGC5000 analyzer “must be so designed and

constructed as to prevent ignition sources arising,

even in the event of frequently occurring

disturbances or equipment operating faults, which

normally have to be taken into account”. The design

of the analyzer is capable of functioning within the

established operational parameters and of ensuring

a high level of protection necessary for the intended

classified Ex zone 1 area.

The notified body LCIE examined the internal components of the PGC5000

and approved the analyzer as Ex ‘py’ for a zone 1 area:

•    The EC-type examination of the PGC5000 series

analyzer and the IEC Ex test report first evaluated

the internal components to Part 15 of the

harmonized conformity standard IEC60079 (Ex ‘n’)

as either being non-sparking, energy limited or

temperature limited to below the specified

temperature class (ref: certificates EC-type LCIE

09ATEX 1017X and IECEx LCI09.0010X).

•    The EC-type examination of the PGC5000 series

analyzer and the IEC Ex test report then evaluated

the pressurization protection of the enclosure to

part 2 of the harmonized conformity standard

IEC60079 (Ex ‘p’) as being suitable for zone 1 area

without electrical power interlock to the

pressurization system (ref: certificates EU-type

LCIE 09ATEX 3006X and IECEx LCI09.0010X).

PGC Certification

This simple pressurization technique for the

PGC5000 is considered an improvement to the

process gas chromatograph analyzer by allowing for

a continual operation without possible disruption

caused by interlocking the electrical power to the

pressurization system. When operated in a zone 1

area, the user of the PGC5000 analyzer is simply

responsible for:

•    Operating the analyzer within the manufacturer’s

established parameters, as described in the

product manuals and the CE conformity

declaration’s special conditions for safe use

•    Providing a reliable supply of protected air for the

enclosure purge and pressurization system

•    Monitoring the alarm state of the pressurization

system in normal operation

•    Responding to the alarm condition of the

pressurization system, which may require

restoring the supply of protected air or the

removal of electrical power and proper isolation

of remaining hazardous live circuits if the area is

potentially hazardous

Introduction

For a classified Ex zone 1 area, the rationale behind

this “Zone 2 by design” analyzer is that the analyzer

must remain safe when operated in an abnormal

condition. In the event of a fault, the PGC5000

provides continual protection:

•    Should a failed component become ignition

capable, the pressurization system prevents the

components from being exposed to flammable

gases or vapors.

•    Should a failed pressurization system expose the

internal components to flammable gases or

vapors, the analyzer’s alarm provision will alert the

user of the failure.

Neither of these single faults would present a

hazard to the potentially explosive atmosphere;

therefore, electrical power interlock is not required

for this type of pressurization protection. Enclosure

doors are not required to be interlocked so that the

electrical supply is disconnected automatically

when doors are opened. The requirement is simply

an alarm provision since there are no hazards inside

the enclosure when in normal operation.

The zone 1 certified PGC5000 analyzer offers simple

pressurization protection, commonly referred to as

Ex ‘py’ or “Y-purge”. This enclosure pressurizing

technique is made possible by ensuring that the

internal components within the analyzer are not

capable of causing an ignition in normal operation,

thus allowing for a reduction in classification within

the protected enclosures from zone 1 to zone 2.
