WCOM51 is the router/repeater for integration of up to 50 wireless devices. The communication is based on
the encrypted Midam KFP protocol, which allows to update the device firmware on a wireless basis across the
wireless network topology. Native modbus map grants seamless integration into the DDC/SCADA systems.
Thanks to the „dual stack radio“ technology, it can read values from WMbus based devices simultaneously.
- Modbus RTU to wireless Midam KFP protocol
- integration of up to 50 Midam KFP devices
- integration of up to 50 WMbus devices
- wireless coverage extension
- wired or wireless integration into SCADA systems
WCOM51 can work in two modes. Direct communication
or cached mode. Each device is mapped to Modbus
RTU register area. Up to 50 devices can be mapped with
configurable offset and length. Communication status is
available through timestamp, comm error and status. Wireless
coverage area can be extended using the mesh functionality,
which is possible thanks to connection of more WCOM51
devices i a row on a RS485 bus. Configuration and data
message are exchanged between repeaters on a real time
basis. Wireless communication uses higher radio frequency
transmitter power up to + 27 dBm and receiver contains
+12 dB preamplifier. SMA antenna connector makes
implementation of high gain external antenna possible.
Direct mounting flex antenna, or external antenna on coaxial
cable with SMA connector can be installed, for example for
mounting outside switchboard in order to gain better radio
signal reception. Gateway configuration is made by software
tools over wireless network, or over wired RS485 terminals.
PLC/DDC and SCADA driver is available. The device has factory-set values to ensure the correct default
function and allows direct reading and writing of values to the
Modbus map, which is available in a separate document.
All settings are also stored in the Modbus map directly in the
device. Before using the device for the first time, it is necessary
to pair it and it is recommended to perform individual
configuration, especially to enter the encryption password.
SCADA system integration
Direct integration into various SCADA systems through wired
Modbus RTU (RS485) protocol is possible.
To pair your own sensors with the WCOM51 GSM gateway, the freely downloadable KFP-Lite software is available, which communicates with the gateway using the WUSB01 wireless USB configurator. Both devices must be powered and placed in close proximity to each other. Using the search function in the software interface, you can view a list of all available devices in range and assign or modify parameters based on the wireless identification code for each individual device.
Using KFP-Lite, it is possible to change the communication frequency (default value 868.95 MHz).
