Point Blue - WITS Protocol

Point Blue is an intrinsically safe, compact Logger/RTU device with integrated
battery and GSM/GPRS or 3G modem, combining the versatile logging and
telemetry functionality of the long-established Metasphere product range with
the convenience of easy installation and rapid deployment using GSM, GPRS or
3G networks.
Point Blue provides real time remote monitoring of up to 5 programmable sensors. It has software
programmable I/O functionality for hundreds of configurable combinations and includes support for
Analogue, Digital and Counter Inputs. The Point Blue can also act as a Modbus master communicating
over RS232 and RS485. In addition to the multiple configuration options the Point Blue offers local
monitoring of battery voltage, cellular signal strength and ambient temperature.
The RTU offers a plug and play solution that minimises the need for additional site visits, with remote
management functions including remote firmware upgrade enabling associated cost-savings. It can store
thousands of records in memory for later retrieval by SCADA systems.
The Point Blue is an ATEX/ IECEx compliant (to Zone 0), self-contained, low cost fit-and-forget unit for use
in harsh and hazardous environments in remote locations. Its design exploits mainstream technologies
which help to minimise costs whilst at the same time ensuring reliability and a long product life. The
latest developments in low power technology are employed, allowing the Point Blue to derive all the
power it needs (including sensor power, if required) from an internal lithium battery pack. This, together
with an integral GSM/GPRS or 3G modem, ensures a long service life with low infrastructure costs.
