TCP are different from serial based Modbus ASCII and RTU The major difference between the Ethernet and serial Modbus protocols is the behavior of the communication model Modbus ASCII and RTU allow only one request on the network at a time Once a request is sent no other communication on the bus is allowed until the slave sends a response or until the request times out However Modbus TCP allows simultaneous requests on the network from multiple masters to multiple slaves TCP masters cannot send more than one request at a time to a slave but they can send requests to other slaves before a response is received The Modbus TCP standard recommends that slaves be able to queue up to 16 requests at a time The MGate MB3000 will queue up to 32 requests from each TCP master for up to 16 TCP masters www moxa pro MGate 4101 MB PBS Quick Configuration Integrate Modbus Serial and Ethernet with Gateways HMI yo PLC Modbus on TCP IP PLC Q IFAI on ee Modbus on RS 23 2422 Device Modbus on RS 484 Ordinarily Modbus TCP and Modbus ASCII RTU are unable to communicate with each other However with a Modbus gateway in between the Modbus serial network and the Modbus Ethernet network TCP masters are able to communicate with serial slaves and serial masters are able to communicate with TCP Slaves Diagnose Packet Format When the communication of MGate works well between PROFIBUS and Modbus protocols MGate won t go i
