ABB Time Synchronization in PGC5000 Series Data System

Measurement made easy

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.

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.
