5. In IPv4 the netmask also called subnet mask is a 32 bit word used to divide a network into subnetworks As for the IP address it is commonly given in the dotted decimal notation This mask is used to indicate which part of the IP address corresponds to the network address and thus which part corresponds to the host identifier The ones delimit the bit field of the network whereas the zeros indicate the host s bit field 2 Modbus TCP protocol overview NB For more detailed information about the Modbus protocol you may want to refer to the official documentation available at http www modbus org Modbus is a Master Slave protocol used for supervisory control and data acquisition SCADA in which the master usually a PLC can obtain and modify parameters contained in the slave s memory via Read Write commands Only the master can send commands to the slave which executes it and systematically sends back a response even for Write commands 2 1 Modbus TCP pattern A typical Modbus TCP frame is formatted as shown below It is composed of a 7 byte header that contains indications about the message followed by the actual data to be transmitted Example 00 58n 00 00n 00 06n Oln 04n BE 00 2015 01 28 soniKKs GmbH Ultrasonics Technology Doc nr XXXX XXxx page 20 of 37 W kke ULTRASONICS TECHNOLOGY The different packets have the following significations Transact 2 bytes

28. fully handle receipt of stale responses with unexpected sequence numbers Unfortunately the Modbus TCP specification says that this sequence number is optional and can be used by a master to match responses to requests however it can usually be just left as zero The Modbus TCP slave just echoes this back in the response Anyway most Modbus TCP OPC servers today do not implement the sequence number So what is your solution if your Modbus TCP master is first generation Slow down your poll rate You have to consider the worst case response time assume all polls timeout If you are only polling a single slave or poll one slave at a time then you can try to disable the MB Pipeline option in the server configuration see page 22 This will either help or make things hopelessly worse If your OPC server or host application relies on pipelining to send more than one outstanding poll at once then disabling the pipeline will essentially stop all data communication in which case you can just turn the pipeline back on The ideal solution is for your Modbus TCP master to not only support the Sequence Number but also support the receipt of the and OxOB extended Modbus TCP exception response Then 2015 01 28 soniKKs GmbH Ultrasonics Technology Doc nr XXXX XXxx page 33 of 37 soniKKs the master never needs to do retries for each poll it will receive either a value Modbus TCP response or a Modbus TCP
