Tibbo Technology Inc., leading in hardware and software solutions for the Internet of Things (IoT), IT infrastructure management, industrial and building automation, remote monitoring and service, physical access control and data center management, has released another software solution, its own OPC server.

1. Open Platform Communications (OPC) Server from Tibbo
Technology
OPC stands for «Open Platform Communications» that is a set of
specifications and standards for industrial telecommunication. OPC defines the
transfer of real-time plant data between control devices from various
manufacturers. The aim of OPC was to support a common bridge for Windows-
based software applications and process control hardware. OPC was designed
to minimize the quantity of duplicated effort made by hardware companies and
their software partners.
Tibbo OPC Server supports the most typical OPC spec - OPC Data Access
(OPC DA), which is used for reading and writing real-time data. Any device that
supports the Tibbo AggreGate protocol can be a data source. AggreGate is a
white-label IoT integration platform utilizing modern network technologies to
configure, control, monitor and support electronic devices, as well as shared
networks of such electronic devices. It also assists you with aggregating device
data in the cloud, where you can "slice and dice" it according to your
requirements. Moreover, the platform allows other enterprise applications
transparently access this data through the AggreGate server.
Tibbo OPC server has embedded AggreGate network protocol. It can both interact
with any Tibbo devices via AggreGate agent protocol and connect to AggreGate
server. The AggreGate agent protocol open-source solution is published for Java,
C#, and C++ programming languages, so your connection scheme is not restricted
to AggreGate server or Tibbo devices only.

2. Examples
A simple example: TPS reads Tibbit #29 (Ambient temperature meter) and forwards
data to OPC server via AggreGate agent protocol.
A more complex example: we have a Windows-based PC controlling a wood
processing machine by means of AggreGate server through the Modbus protocol. If
Tibbo OPC server is linked with AggreGate server, the data from the machine is sent
to Tibbo OPC server, and therefore, we can operate and monitor the machine via
any OPC client.
Technical Specification
● Compatibility with Windows XP/2003 or later (Microsoft Visual C++ 2013
redistributable is required - installed automatically)
● Support of DA Asynchronous I/O 2.0 and Synchronous I/O with COM/DCOM
technology
Tibbo OPC Server transmits the information on the Value, Quality and Timestamp of
an item (tag) to the OPC Client applications. These fields are read from the
AggreGate variables.
The process values are set to Bad [Configuration Error] quality if OPC Server loses
communication with its data source (AggreGate Agent or AggreGate Server). The
quality is set to Uncertain [Non-Specific] if the AggreGate variable value is empty.
In the following chart below you can see a concordance table of the AggreGate
variables and the OPC data types:
AggreGate Data Type OPC Data Type
INTEGER VT_I4
STRING VT_BSTR

3. BOOLEAN VT_BOOL
LONG VT_I8
FLOAT VT_R4
DOUBLE VT_R8
DATE VT_DATE
DATATABLE OPC VT_BSTR (by default)
COLOR VT_I4
DATA VT_BSTR
