Do you use redundancy in your solutions? As far as mission critical applications are concerned, our customers' answer is usually yes. Redundant D2000 application servers, redundant LANs, redundant archives, communication processes and communication routes - depending on the nature of the application, they use some or all of the redundancy types supported by the application server D2000.
Great news for all D2000 users! We just published a brand new version of D2000 programming platform for Windows and it is available online. D2000 V12.0.61.u3 has new features and also fixed bugs. What do you need to know about it? Changes in our components are going to help you with building.
Raspberry Pi is big phenomen in the field of technology and we are able to utilize it´s potential in Industry 4.0.
I bought Raspberry Pi (RPI) on AliExpress also with the small box. I’ve already had more efficient (around 5V/2A) power supply to a mobile phone, charging cable with micro USB connector and microSD card form a mobile phone. I didn’t have to buy those.
A few days ago, a colleague came to me and asked for advice. “I need to sum, more precisely I need to integrate the energy consumption but in a way that at the beginning of every work shift, the number will be zeroed. So, the diagram would be resembling teeth of a saw – it will rise, and rise, and then on the edge of the work shift, it will be zero again. Could this be done in an elegant way – preferably right in the archive without needing to calculate somewhere in the ESL script?”
How we have chosen the default web server for the next D2000 autumn version V12.1.?
A demonstration of how you can replace the Moxa NPort for a Raspberry PI, e.g. during data acquisition from electrometers.
This is a third blog of a series dedicated to topic of archiving on the PostgreSQL platform. In past blogs, I wrote about accelerating the Arcsynchro utility while loading PostgreSQL depositories (Arcsynchro and PostgreSQL depository databases) and about results of migration (Depository databases migration to PostgreSQL in practice). Today's article is related to several months of experience with the operation of a large archive and depositories on the PostgreSQL platform.
Some time ago, you could have read about features of the extended communication protocol Communication – Ethernet/IP. Lately, it was necessary to start communication between the MES system built on the D2000 technology and the control system of a cogeneration unit of a particular customer. The control system is built on the PLCs made by Rockwell company (the main controlling unit was ControlLogix 1756 and smaller auxiliary wer CompactLogix 1769). So, how to establish the communication?
A major change has recently been made by ORACLE, which also affects the use of our D2000 programming platform. The license change prevented the use of Java Runtime Environment (JRE) for commercial purposes without a paid license. How can we solve current situation from the perspective of using the D2000?
