LOYTEC
Version 6.2
LOYTEC electronics GmbH
A temperature sensor object which outputs the current value of the external
temperature sensor (optional).
A real time keeper object, which outputs the current system time.
8 L-VIS functional blocks which can be used to place static or dynamic NVs
related to the data points used in the project.
Network scanning to find other device on the network and help in creating the
required network variables on L-VIS.
The LVIS-ME200, LVIS-ME21x, and LVIS-3MEx models (BACnet) also provide:
Up to 512 server objects, accepting COV subscriptions. Available object types
are analog, binary and multi-state, each as input, output, or value object.
BACnet/IP or MSTP connectivity (selectable via jumper or device configuration
setting) as well as integrated router, BBMD, and slave proxy functions when the
device is connected to both networks at the same time.
Network scanning to find other devices and their objects in the network and use
them on the L-VIS device without the need to manually enter device and object
instance numbers.
Supports COV subscription and polling of remote server objects with automatic
selection of the best method (COV if available). See also the PICS document for
details regarding the BACnet protocol implementation.
Support for Modbus/RTU in addition to Modbus/TCP. Master and slave mode
are supported. Modbus/RTU cannot be used together with BACnet/MSTP, since
both protocols use the same physical interface.
The LVIS-3MEx models have the following extended features:
Support BACnet and CEA709 operation at the same time. All features listed
above for the CEA709 and the BACnet flavors of LVIS apply to all devices of
the LVIS-3ME series as well. LVIS-3ME devices maintain full binary backward
compatibility to all projects written for LVIS-3E11x/ME21x devices.
Provides an OPC UA Server in addition to the OPC XML-DA server.
Additional Controls like webcam or knob control, as well as support for complex
writing systems, which is not available on older hardware due to resource
limitations.
Significantly improved CPU, memory, and storage capacity to support larger and
more complex projects than their predecessors.
