This document is intended to be used as a reference for network administrators and contains a list of all the static TCP/UDP ports used by Rockwell Automation hardware and software products.

In the Siemens PLC, we have several types of CPU communication ports available to communicate with other devices like MPI, DP, PTP, ProfiNet, and EtherNet.

Apr 4, 2003 · For PLC-5E or SLC-5/05, you need to forward TCP Port 2222 to the IP address of the controller. For ControlLogix, you need to forward both TCP and UDP port 44818 to the IP address of the controller.

Today, I would like to share with you some common connection ports and communication protocols of PLC. 1. Difference between RS232 interface and RS485 interface. I. Physical Structure of Interface. 1. RS232 interface: one of the computer communication interfaces.

You must be familiar with OSI layers and different types of communication hardware ports used in PLC, to understand the whole cycle of communication in a better way. We will here see the various communication methods used in a PLC: It is a protocol that works under Common Industrial Protocol (CIP), which is an open application layer protocol.

Apr 16, 2021 · The PLC communication can be done by using a twisted pair of wire or by remotely through a telephone or radio modem. Many types of PLC have a built-in communication port, using RS232, RS 422, RS 485, or Ethernet. The modern PLC can communicate over a network to some other system.

Feb 12, 2024 · Here are the default port numbers for some common Omron PLC communication protocols: TCP/IP: Port 9600 is commonly used for FINS communication over TCP/IP. UDP: Port 9600 is also often used for FINS communication over UDP. Port 502 is the default port number for Modbus TCP/IP communication.

Ethernet Port Numbers The CLICK PLC communicates over Ethernet using the TCP and UDP protocols. The port numbers used by CLICK are listed in the table below. This information is sometimes necessary for firewalls and router NAT tables.
