Interfacing a RS485 device with S7 200 CN PLC Entries ... Hello,I have a third party RS485 device (possibly using MAX485 transceiver), I want to interface with S7 200 CN PLC to control it in Freeport mode.Setup is:PLC port 0 pin 3 connect to RX TX of the devicePLC port 0 pin 8 connect to RX TX of the devi RS 485 2 wire communication from S7 1200 PLC (CM 1241 ... I’m currently working on a project that requires communication to be established from SIEMENS S7 1200 PLC to the Distributed Control System (DCS) via MODBUS RTU protocol. The PLC is configured as a MASTER in the PLC program [see attached link for screenshots] and the DCS has to be configured as a SLAVE. RS 485 Repeater Siemens Figure 4 1 Installing the RS 485 repeater on an S7 300 mounting rail Removing the repeater from an S7 300 mounting rail To remove the RS 485 repeater from the S7 300 mounting rail: 1. Loosen the fixing screw of the RS 485 repeater (1) and 2. Pull the RS 485 repeater up and out (2). 1 2 What is RS485 and How it's used in Industrial Control Systems? Just like it’s older brother RS232, RS485 is a form of serial communication. Think of RS485 as the younger, faster brother of RS232. Guidelines for Proper Wiring of an RS 485 (TIA EIA 485 A ... greater than, 10Mbps. RS 485 is designed to transmit this information over significant lengths, and 1000 meters are well within its capability. The distance and the data rate with which RS 485 can be successfully used depend a great deal on the wiring of the system. Wire RS 485 is designed to be a balanced system.

C) The maximum bus length is limited by the transmission line losses and the signal jitter at a given data rate. Because data reliability sharply decreases for a jitter of 10% or more of the baud period, Figure 7 shows the cable length versus data rate characteristic of a conventional RS 485 cable for a 10% signal jitter. Design guide DATA COMMUNICATION MODBUS RS 485 RTU For ... The RS 485 consists of three wires: • RS 485 A (D ); • RS 485 B (D ); • GND. The two wires RS 485 A (D ) and RS 485 B (D ) propagate a differential communication signal. In addition there is the ground wire for the common mode voltage reference. The recommended maximum Modbus cable length between the EKE( EKD EIM) and the system A Guide to munication with S7 200 PLCs When connecting to a single S7 200 PLC, the PPI RS485 connection of the PPI Adapter can be connected directly to the S7 200 PLC. When connecting more than one S7 200 PLC, use standard Profibus cable (or equivalent) to connect the PLCs together. Modbus RTU RS485 Siemens Modbus RTU is an open, serial (RS 232 or RS 485) protocol based on master slave or client server architecture. The protocol interconnects field equipment such as sensors, actuators, and controllers and is widely used in both process and manufacturing automation.

When using shielded cables, the cable glands are needed to secure the shielding. 1. Install the cable gland (2) with the nut (1) on the flange between the fastening tabs (3). 2. Using MODBUS for Process Control and Automation many devices over a single twisted pair wire. The original scheme ran over RS232, but was adapted to run on RS485 to gain faster speed, longer distances and a true multi drop network. MODBUS quickly became a de facto standard in the automation industry, and Modicon released it to the public as a royalty free protocol.
