Application configuration
Within the mimic
LEDs are connected to M-Net LED driver nodes using standard cable sets. M-Net instrument tiles or simple instruments are plugged into appropriate M-Net instrument modules.
When a large number of instrument nodes are installed these nodes each connect via a standard cable set to an intelligent router, which provides power and network connections.
Mimic communicating with PLC, DCS or computer
Wherever possible the Modbus RTU protocol is used as standard. When this is not possible generally a programmable "gateway" is used, e.g. DH+, Profibus, etc. Often the programmer can address the mimic as if it were native I/O blocks.
Mimic panel not connected to a PLC or computer
For applications where the mimic panel receives its inputs from plant level sensors around a site with distributed I/O modules strategically located to reduce site cabling.
M-Net components
Gateway
The mimic in linked via a gateway to a host system. Most PLCs, DCS and computer systems can be interfaced to M-Net. Supported protocols include Allen-Bradley DH & DH+, Siemens L2 Profibus and Modbus, for which a direct connection is possible without the need for a gateway.
Intelligent router
Provides power and network data to nodes and can impart standard and application-specific mimic functionality to the system.
M-Net LED driver node
For connection to up to 64 LEDs via standard cable sets. Each node includes 8 input channels.
M-Net instrument node
Each node module will accept any of the M-Net instrument tiles to be interfaced directly to M-Net. The range of M-Net instrument tiles includes LED bargraphs and 4-digit DPMs in a range of tile sizes.
M-Net analogue instrument node
Each node drives 4 moving coil meters or low cost instruments.
