Matching the baud rate is not enough to ensure reliable RS485 communication. The PLC must also determine where each message ends and when the next request can be transmitted. The EX-6301 is a single-channel free-port RS485 communication module designed to connect drives, meters, transmitters, intelligent electrical devices, and other serial

Establishing a Modbus TCP connection is usually only the first part of a remote IO project. Long-term operating reliability also depends on whether process-data addresses, physical module order, and output behavior after a communication failure are planned consistently. The Decowell EX-1130 is a Modbus TCP bus adapter for digital, analog,

When maintaining an existing EX-1120 remote I/O station or considering an EX-1121 as a replacement, comparing only the EtherNet/IP protocol and maximum I/O capacity is insufficient. Both adapters support up to 32 EX-series I/O modules and provide maximum input and output capacities of 504 bytes. Their network interfaces and communication

Installing an EDS file and finding an adapter in the engineering software do not complete an EtherNet/IP remote IO configuration. When the EX-1120 connects different digital and analog IO modules, engineers must calculate input and output bytes separately. The software module order must also match the physical station. An incorrect

A CANopen communication fault does not always appear as a completely offline device. Some problems prevent the EX-1050 from entering the operational state, while others allow the network connection to remain active but cause shifted input addresses, inactive outputs, or incorrect PDO lengths. The EX-1050 is a CANopen adapter for
