Can alarm signals be implemented using communication signals?
Thread Content
During the design process, it was found that the control system required high and low alarm signals, but these alarm signals were not to be used for interlock functions. Is it possible to transmit these high and low alarms to the host computer via field instruments?
Yes, the alarm signal can be transmitted via communication signals. During the design process, on-site instruments can be used to send high and low alarm signals to the host computer, where corresponding processing and display are carried out. This enables real-time monitoring and processing of alarm signals, allowing operators to promptly understand the system status and take appropriate actions. .
