Click PLC Ethernet Communication Overview

Click PLC Ethernet Communication Overview The CLICK and Click PLUS PLCs that can communicate over Ethernet use the TCP and UDP protocols. The port numbers used by the CLICK are listed in the table. This information is sometimes necessary for firewalls and router NAT (Network Address Translation) tables. For TCP and UDP communications such as Modbus TCP and EtherNet/IP, there are limits to the number of “connections” allowed. Each connection uses memory and time in the Click PLC which will affect its overall performance. EtherNet/IP also has the concept of a “CIP” (Common Industrial Protocol) connection. This table displayed lists the connection limits for the CLICK or Click PLUS PLC. Programming and examples of the Click and Click PLUS PLC series can be found at this URL: https://accautomation.ca/series/click-plc/ https://accautomation.ca/click-plus-plc-mqtt-communication/ https://accautomation.ca/productivity-1000-plc-click-ethernetip-remote-io/ https://accautomation.ca/click-plc-send-and-receive-instructions/ There are several reasons why we are using the Click and Click PLUS PLCs. Here are just a few. - Investment is low for the hardware and the software is free - Standalone PLC with built-in I/O - Communication ability - Ethernet Port, RS232, RS485 - support for protocols such as Modbus RTU, Modbus TCP, etc. - Ability to expand the system with a variety of modules including RTD and Thermocouple inputs directly.
