The completeness of the library of communication protocols for a SCADA / HMI software is the real strength because it provides connectivity to field devices.
Sielco Sistemi strives daily to maintain the internal library of its SCADA software Winlog Pro up to date with the evolution of the communication protocols of the most common devices for industrial automation and building automation (Siemens, Allen Bradley, Omron, Mitsubishi, Schneider Electric etc.) through a continuous search and optimization work.
Winlog Pro supports communication with most of electronic instruments available on the market (PLCs, controllers, indicators, I/O modules, etc.) thanks to an extensive library of native communication drivers and to the OPC Client interface.
OPC (OLE for Process Control) is an industrial standard, created by main worldwide leading automation manufacturers, that allows data exchange between different software components without need of any special adjustment.
OPC Client driver supports data access (DA) to OPC servers DA 1.0, 2.0 and 3.0; it can interface both local OPC Servers located on the same PC (through COM objects) and remote OPC Servers (through DCOM objects) located on different PCs linked to the same LAN.
Both native communication drivers and OPC Client interface are included in the basic Winlog Pro package.
In Winlog Pro new version all communication drivers have been revised, in order to uniform the configuration of the various protocols. New communication protocols were also included, such as M-Bus protocol and Mitsubishi MELSEC.
