Profibus-DP Communication Between S7-200 and S7-300

Profibus-DP Communication Between S7-200 and S7-300 PROFIBUS Fieldbus 1. Profibus-DP Communication Between S7-200 and S7-300 PLCs 1. Analysis: The S7-200 PLC does not support the DP communication protocol and does not have a Profibus-DP interface, so it cannot be directly connected as a slave. However, it can be connected to the Profibus-DP network by adding … Read more

S7-400 One-Way Communication Based on PROFIBUS (STEP7 v1x)

The S7 protocol is the standard protocol used for communication between SIEMENS S7 series products. Its advantage is that both communication parties can establish a communication connection through the S7 protocol, regardless of whether they are on the same MPI bus, the same PROFIBUS bus, or the same Industrial Ethernet. The data exchange is independent … Read more

Issues with RS485 Repeaters and Profibus Signal Voltage

Search on WeChat Technical Training There have been persistent issues with Profibus communication at a certain brewery. Previously, SIAS and on-site engineers had re-planned the entire Profibus network topology, but there were still instances of DP slave devices dropping out, occurring multiple times in a short period, severely affecting the factory’s normal production. Therefore, the … Read more
