Modbus RTU/ASCII from the accessible internal registers of the device. The first tab called Internal Registers includes the table of internal registers of the SFAR-S- ETH module, which are recurrently refreshed by www website. These registers are used by adding remote requests in the Devices tab. - Page 25 SFAR-S-ETH User Manual The configuration of the requests can be saved by the user in an external file and after reading automatically re-enacted to the device. The configuration is saved in the memory of the device and is only reset after re-enactment of the default configuration (more details in 3.5.1 - Default settings).

Page 26: Modbus Tcp Working Modes
After processing the request and preparing the response, the module sends it accordingly to the Modbus TCP protocol’s specification. If the request is not addressed to the SFAR-S-ETH module and the TCP gate mode is set, the device converts the request into the Modbus RTU/ASCII and sends it to RS485 bus. The SFAR-S-ETH waits for the defined time for the response and blocks the access to the RS485 bus for other clients, to avoid the packages’... -
Page 27: Device Table
While working in the Device Table mode, the client connects with the device in the same way as in the case of the gate mode. One considerable difference is that the SFAR-S-ETH module will ignore all the requests which are not addressed to it. The communication with external devices is only possible through the configuration of remote requests by the www website (more details in 9.6 –...
