The NetLink Light 6 is a TRACE MODE HMI client software. The NetLink Light is designed for use on additional workstations, connected to the TRACE MODE 6 servers.
TRACE MODE NetLink Light 6 has the following main features:
real time data exchange with TRACE MODE servers, e.g. RTM, RTM+ or its modifications, as well as with Global Logger and with controllers run under Micro RTM;
data processing with the IEC 6-1131/3 standard programs;
process visualization in HMI screens and trends;
visualization of the process history from SIAD/SQL 6 or from relational DBMS;
supervisory control via the TRACE MODE servers.
The NetLink Light 6 based HMI is represented in the TRACE MODE 6 project as a separate node having its own network TCP/IP address. The NetLink Light node does not contain its own I/O channels, but only the calls of HMI screens and programs. The HMI screens can be copied from any node of the project, or designed specially for the console.
The NetLink Light 6 based HMI can connect to servers through all physical interfaces available in TRACE MODE, e.g.:
TCP/IP local area network;
modem on dedicated phone line;
modem on dialup line;
GSM SMS based network;
One NetLink Light 6 can connect simultaneously to many TRACE MODE 6 servers, therefore the NetLink Light 6 HMI screens can display the information received from different TRACE MODE RTMs, RTM+ and Micro RTMs. It is possible to connect the unlimited number of NetLink Light 6 HMI clients to a single TRACE MODE server.
The following training video shows how to connect a NetLink Light to several servers simultaneously:
The TRACE MODE NetLink Light can connect to controller with Micro TRACE MODE directly. Here is the video showing how to do it:
For human-machine interface (HMI) development, users may employ the same data presentation forms and control elements, as for RTM and RTM+ HMI screens. The TRACE MODE NetLink Light 6HMI graphics and logical programs are independent from the HMI graphics and programs on the TRACE MODE servers and other consoles. Even, if the same templates were used on the HMI screens, the operators can work independently. Eventual collisions between several operators, working simultaneously with the same HMI elements, are eliminated by TRACE MODE 6 security system. The security system checks the operators login and password upon control system loading and grants them access to the control system components defined in his personal security profile only.
While used with redundant real time servers (e.g. Double Force RTM), the NetLink Light provides automatic redundancy for clients. In case of the server failure, NetLink Light will switch to the stand by server automatically. Dual and triple redundancy is supported.
NetLink Light 6 provides easy, but at the same time, powerful solution for the additional client workstations design for a distributed process control system. Minimum time and engineering efforts are required for additional project nodes development. The NetLink Light 6 provides all necessary functions for remote monitoring and control.
License policy: The NetLink Light 6 console is licensed for 1 PC. Versions with different templates e.g. screens, programs, SQL-queries support are available.
