Hello folks.
Would like some ideas on this 'little' problem I have. Or rather a problem my boss has but has delegated me, nice!
I have a PC based CITECT SCADA system in an engineering plant room office. When certain alarms are generated by the SCADA system I need to give audio and visual alarms in a security gatehouse that is some 400 metres from the PC.
Unfortunately our customer informs us that the cable duct between the engineering office and gatehouse collapsed some years ago and so is not available!
The only thing I can think of at present is to dial-out via a modem when an alarm is generated. However I have no experience with what to connect the other end?
I have thought about using a small 'mini' PLC with a built in serial interface, and triggering digital lamps and sounders in an alarm panel.
Would a smallish HMI do the same thing. The visual
bit is OK, but do any HMI's have buzzers, sounders?
Cheers.
