ENsigfox DRY CONTACTS- Guide utilisateur / User guide version V1.2.063Page of 804. DESCRIPTION OF THE FRAMES4.1. Uplink framesAll of the uplink frames of the product to the network (uplink) always have a size of 11 bytes.4.1.1 Fixed bytesThe first two bytes of the frame are systematically dedicated to indicate the frame code and the status as presented below:0 1 2 3 4 5 6 7 8 9 10Code Status PAYLOAD4.1.1.01 Byte codeThis byte contains the code associated with the frame to facilitate its decoding by the data system.4.1.1.02 Status ByteThe status byte is broken down in the following way:Alarm Status Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0Frame Counter Réservé CommandOutputHW Low Bat ConfigNo Error0x00 to 0x07X 0 0 0 0Configurationdone X 0 0 0 1Low bat X 0 0 1 0HW Error X 0 1 0 0CommandOutput Done X 1 0 0 0Details of the fields:• Frame counter: Frame counter, it increments at each transmission and allows the user to see quickly if a frame has been lost. It countsfrom 0 to 7 before looping back.• Command Output Done: bit at 1 if at least one output has been properly controlled.• HW: This bit is set to 1 when a hardware error has occurred, for example a writing problem in the EEPROM, a reading problem on theADC, etc. The product must be returned in to the service dept.• Low Bat: bit at 1 if the battery voltage is less than 2.5V (defined in register S522), otherwise 0. This information remains permanent.• Config: bit at 1 if a configuration was carried out during the last downlink frame, otherwise 0. This bit returns to 0 as from the nextframe.E.g.:A value of the status byte equal to 0xAB (= 10101011 in binary) gives:• Bit 7 at 5 = 101 = 0x05 i.e. a frame counter at 5• Bit 4 at 0 = 01011 in binary is the validation of the configuration, a low battery alarm and a successful exit command.
