Are radio telemetry systems reliable for industrial applications?
Answer:
Yes, if done properly. Our view is to take the safe road and use
licensed radio. Normally, 2-5 watt UHF is ideal for the industrial
plant environment, where, not only distance, but the ability to
transmt through structures interference free is vital.
Question:
How will we know if a remote telemetry units is not functioning.
Answer:
Probably the most efficient way is to program a poll timer into
the master terminal for each remote unit with each timer starting
over when a reception takes place. This way if there is no
reception for the set period, the associated timer will time out
and cause a failure alarm.
Question:
Does the master terminal sequencially poll all the remote sites
on a continual basis?
Answer:
No. Normally, the most efficient way to configure a telemetry
system is to transmit in from the remote site in the event of a
change in values set by a predetermined threshold. If there is no
change, then there should be a periodic poll, ie. every 10-30
minutes, to let the master terminal know that the remote terminal
is operational.
Question:
If a change in the programming of a remote site is desired, does
the new program have to be loaded at the remote site location?
Answer:
A unique feature with Gastronics' RTU telemetry systems allow us
to send an update for a remote site through the master terminal
via radio.
Question:
Can the factory change or update the software from the home
office?
Answer:
Yes. If a PC is running with an Access Software.
