Outsourcing the Migration of Plant History

-

When an organisation makes a decision to introduce a different Plant Data Historian the requirement to retain visibility and access to existing historical data can be a challenge. There might be multiple years’ worth of valuable plant data associated with the legacy Plant Data Historian which somehow needs to be migrated to the new Plant Data Historian.

Typically the same or a similar tag set is established on the new Data Historian and plant data will start to be recorded in the new system. There might be a switch over period where both the old and new systems each record data until the Plant is convinced that the new system is fully commissioned. All reports and web-portal views will now reference the new Plant Data Historian.
Data migration is typically done in one or two tranches and the legacy Data Historian is finally decommissioned and all costs associated with its maintenance cease.

In our experience the users of plant data are not empowered to attempt this onerous task on their own and its complexity can be a major distraction to their already busy schedules.

The IDX Tag Manager and IDX Historian with its Historian Data Migration Tool  enable IDX to offer an outsourced service to cost-effectively and reliably handle this process for a Plant.
There is no requirement for the customer to purchase any hardware or software, they simply need to provide access to the legacy and new Plant Data Historians.
Rather the customer will be charged a fee that will cover the equipment rental and engineering effort to complete the data migration.

Migration process overview when migrating and merging two historical sources into a single target using the Migration Tool.

The data migration is set-up offline on one or more virtual machines and when ready migrated data is “attached” to the new Plant Data Historian and can be accessed by users.

A typical plant data migration project for 50,000 tags over a period of 4 years would take 1-2 months to complete.

Common pitfalls when installing a Modbus RS485 network on site

Last week IDX were called to site at  a large commercial residence building in Pretoria, South Africa. Where our  client was implementing an IoT solution for remote monitoring and control of various HVAC and power systems in the building.  The control system the SI chose in this case was a Modbus enabled Industrial Micro PC called the Revolution PI. The client had Modbus sensors connected to boilers, air conditioning systems, ventilation systems and power meters. The Modbus  communications between the controller and the sensors were intermittently failing due to various installation and implementation faults: 1. Earthing and Shielding Within any fieldbus communication installation, one of the requirements to ensure uninterrupted operation is to implement adequate grounding and shielding techniques. Effective grounding and Shielding help to prevent electrostatic and electromagnetic pickup, which can lead to failed communications. Some of the shielding and grounding req

The SG-gateway family is a current leading Smart Grid application solution, acting as a remote terminal unit for the energy market. The SG-gateway enables the remote control and management of electrical equipment in power grids, controlling and monitoring assets, processes and installations in the field. Networking and interfacing between various fieldbuses and Industrial Ethernet protocols is where this gateway shines, allowing cross interfacing between: IEC61850 (Client/Server) IEC60870-5-104 (Client/Server) Modbus TCP (Client/Server) Modbus RTU (Master/Slave) Various Serial RS232, RS485 and RS232 PROFIBUS PROFINET EtherNet/IP Here are some application examples: Transmission can also be made available via Ethernet or 3G VPN connection into your server. The SG-Gateways sports an easy web based configuration tool using a standard browser, configuring with a simple drag and drop method. Choose the right SG-gateway to suit your requ

IDX 8 Tag Manager - Managing the unmanagable?

-

Tag management of real-time data systems can prove challenging. As an industrial IT company we frequently come across the problem where tags need to be migrated from one system to another or where tags need to be synchronised and maintained between systems including historians. Generally, this ends up being a manual process, often involving Excel and much diligence and patience of the maintainer’s behalf. IDX Unifig was the first incarnation of a tool we designed with the aim to simplify the migration and management of tags between systems. The tool worked, but with as with most first editions of software tools, we could see the need for improvement and refinement of the approach used. Thus Tag Manager was born, and has become the key stone in the IDX 8 software suite. All other IDX 8 modules, such as Data Exchange, Alarms and Events and the Historian use Tag Manager to store and reference tags. The comparison result we like to see - no changes.   Tag Manager employs a plug
