If the AquaVent has been programmed to record on its own independent schedule, data can be downloaded from the AquaVent using a laptop and USB Connector Cable in the field (see Figure 3-1). Temporarily disconnect the Wellhead from the RS-232 or RS-485 Connector Cable, preferably in between recordings by the MODBUS master, as the master will not retry for any missed recordings. Connect a laptop and download the independently recorded data.
If the AquaVent is disconnected from the MODBUS network, and the MODBUS master tries to communicate with the AquaVent, the MODBUS master and the rest of the sensors in the network are not disrupted. After the data download is complete, the AquaVent is easily connected back into the MODBUS network without disruption.
