” Module usage The WB169-RFG module is intended for data transfer from the RF modules of remote reading in 169 MHz radio band and a central computer application that receives and processes the data. The module receives radio messages coded according to the Wireless M-Bus EN 13757-3 and EN 13757-4 standard for the 169 MHz band, checks their correctness, encodes ( repacks”) them into IP/UDP frames and sends them to the configured IP address... -

The ”write”, ”cread” and ”clear” commands serve for management of saving data in the module memory. The module contains two sets of configuration: operating configuration and saved configuration.
- Page 23 This command is recommended to use only by users with good knowledge of the system or after consultation with the manufacturer. Availability of IP-connection between the WB169-RFG module and any computer on the Internet can be checked by using the ICMP ”ping” function. By entering of ”ping [address]” command the system sends a control ping to the specified IP address and displays the result.

UDP message data content The data content of the message is encoded using SOFTLINK’s proprietary ”NEP” encoding system, where each type of variable has its own designation ”OID” (Object ID), which determines the meaning, character, and data type of the variable. For variables that can be used multiple times (several inputs, temperatures, voltages ...), the order number of the variable ( Index”) is also mandatory. -

Page 36: Operation Of The Wb169-Rfg Module
Receiving radio messages from surrounding radio modules and forwarding of the messages to the superior system via Internet the WB169-RFG module performs fully automatically. Take into consideration that the broadcasting systems according to the Wireless M-BUS standard has no protection against interference during transmission (a signal collision, which occurs when two modules broadcast at the same time), so that temporary loss of data from some modules can commonly occur in case of operating of a large number of modules in one radio network. -
