6.1.2 Denition Files
The role of the denition le is to inform the gateway on the data which it will be reading/writing on the
Modbus slave as well as how the gateway will access this data.
The link between the denition les and the gateway is provided via the conguration le prexID_daq.
ini. The format of the denition les, including a section dening the requests to be sent and another
describing the variables which are to be written/read is described in chapter 7.3 “Structure of a Modbus
denition le”.
6.2 Initialization
Initial conguration of the unit is necessary to enable connection to the remote FTP server. This
conguration can be carried out either via the on-board Web Server or by SMS if a functional SIM card
has been inserted in the gateway.
Local conguration of the WebdynModbus affects only the variables in the conguration le: prexID_
cong.ini.
Here is a list of the variables accessible via the local web interface (http) and/or via SMS commands:
