Communication connection method between the complete set of equipment and the automatic control system
Thread Content
The communication methods between the company and the complete equipment supplied by various equipment manufacturers include RS232, MODBUS, 485, etc. How can standardized communication methods be established, and how can unified standards be set?
Well, it depends on how you approach the equipment manufacturers; generally, manufacturers are capable of handling such standard communication protocols
Just make your request; what else can you do?
When establishing unified design specifications, confirm them with the manufacturer and the client.
Either specify communication methods such as 485 directly, or require in the technical specifications that all on-site signal hard contacts must be fed into the DCS for processing.
