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.
APPLICATION
- 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
FUNCTION
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 change the encryption password.
SCADA SYSTEM INTEGRATION
Direct integration into various SCADA systems through wired Modbus RTU (RS485) protocol is possible.

PAIRING
Two devices are required for mutual communication. Both must be powered and located in close proximity to each other. Set the PRG switch on WCOM51, then set the PRG switch or the DIP switch on the remote device. From this time on, manual intervention on remote device must be performed within 10 seconds. This confirms the pairing of both devices. Switch both PRG and DIP switches on both devices again. While setting up more complex wireless topology, PC and apropriate software tools are recommended.
