Page 22: Modbus Protocol
4- Modbus Protocol 4-1 Introduction 4-1-1 About Modbus protocol Modbus is a very commonly used communication protocol and and with it, control equipment produced by different manufac- communication convention in industry. Modbus protocol turers can be connected into an industrial network for central- includes RTU, ASCII and TCP type, and Modbus-RTU is the ized monitoring. - Page 23 field. The response supported by almost every commercial SCADA, HMI, OPC Server message from LSCM-D also consists of the Modbus and data acquisition software program in the marketplace. This protocol, including the domain to confirm the action, any makes it very easy to integrate Modbus compatible equipment into data to return, and an error detection domain.
