Difference between OPC UA and OPC DA OPC UA OPC DA 1. It is platform-independent and can be used on any operating system. 1.It is available on Windows only. 2.It is more interoperable because it is platform independent. 2.It can …
What is OPC ? OPC (OLE for Process Control) was introduced in 1996 as a protocol designed to replace older communication protocols like Modbus RTU or Profibus, which were primarily used for field-level communication, At that time, OPC was exclusively …
What is DLR? What is Device Level Ring? DLR, or Device Level Ring, is an Ethernet/IP protocol introduced by ODVA. We can utilize DLR switches exclusively within Ethernet/IP networks. Put simply, if you have a device intended for a single …
What is EDS file? An Electronic Data Sheet (EDS) file is an ASCII text file that contains essential information about an Ethernet/IP device or adapter. To establish communication between scanners and adapters, you need to include this EDS file in …
Types of Ethernet/IP communication Implicit Communication: Periodic communication between an Adapter and a Scanner, often referred to as cyclic communication, is employed to facilitate the regular exchange of real-time data between the Scanner and the Adapter. This form of communication …

Difference between Modbus TCP and Modbus RTU The Modbus messaging protocol was developed by Modicon. Within the protocol, both Modbus RTU and Modbus TCP/IP are widely used. Nowadays, Modbus TCP/IP is gaining popularity due to its Ethernet-based nature and user-friendly …
What is Modbus TCP/IP? Modbus TCP/IP is a client/server-based application protocol that utilizes Ethernet as its physical layer. Here TCP means transmission Control Protocol. It is a deterministic protocol as it Accommodates to TCP standards. TCP confirms whether each request …
We will see steps to solve communication issues between Master and Slave Device using Modbus RTU protocol.
Modbus protocol is widely used in manufacturing world. It is a serial-based protocol that supports the master-slave concept. In this protocol, the master initiates communication.
