lab2lab control modules all run firmware developed by SPT Labtech. The firmware processes output commands sent from the lab2lab Director software (e.g. to open a Blow valve) and sends back updates and confirmation messages about the state about the of the I/O. Each networked device also sends a “heartbeat” signal every ten seconds. The signal not only assures the Director application that the device in question is functioning but also lists the binary status of all inputs and outputs.
Use lab2lab Director to shut down lab2lab components for maintenance or repair, following the instructions in the 'lab2lab Systems Administrator's Manual'.
