》》PROFIBUS DP to Modbus/TCP Gateway Operation Guide Abstract： This article takes the NT100-RE-DP gateway as an example to implement communication between Modbus/TCP Client and PROFIBUS DP devices, thereby integrating PROFIBUS DP slave devices into the Modbus/TCP network. The following will gradually demonstrate the configuration steps of this gateway, which are similar for other models in … Read more
Easy Learning of TIA Portal SCL Programming Structured Variables Understand S7-1500 PLC Reading and Writing SQL Microsoft Database in Seconds How to Design a Standardized Modular HMI Interface? Will Structured Programming with ST, SCL, etc. Become Mainstream? PROFINET and PROFIBUS are two fieldbus technologies launched by the PNO organization. The two are not comparable; PROFINET … Read more
*Follow to receive 2798 PLC wireless communication cases* The PROFIBUS bus is a purple shielded twisted pair cable, with the two cores being red and green. When connecting to the bus connector, the wiring must be done according to color, generally A1 and A2 are green, while B1 and B2 are red. 2. Devices on … Read more
Taking advantage of the previous article’s momentum: Foundation Fieldbus H1 main products have been upgraded to Ethernet/IP or Modbus TCP. Here, I present a product that can directly convert the Profibus PA protocol to Ethernet/IP or Modbus TCP protocol. This is the main content of this article. 0x00 Protocol Introduction The Profibus protocol is operated … Read more

Click on the arrow to follow us! When the S7-1200 acts as a DP Master, if the DP slave is lost, the CPU will not stop, and there is no need to download the organization block to the CPU. For fault diagnosis of PROFIBUS DP, the following methods are available: 1. Through the indicator lights … Read more
A customer of Siemens 840DSL processes impeller products, with loading and unloading performed by a third-party robot. Quality inspection personnel found through multiple random checks that: for every 500 products processed, about 10 products have the following quality issue: there is a noticeable knife mark on the back of the blades. When operators performed manual … Read more
PROFINET and PROFIBUS are two fieldbus systems introduced by the PNO organization. There is no comparability between the two; PROFINET is based on industrial Ethernet, while PROFIBUS is based on RS485 serial bus. The protocols of the two are completely different due to the differing media, with no connection between them. However, both have excellent … Read more
【Introduction】There are multiple methods for integrating PROFIBUS PA field devices into TIA Portal.The type of integration is determined by the communication standard used on the CPU interface.Two different communication standards can be used here: Ethernet-based PROFINET communication or the classic PROFIBUS DP master system. (1) Advanced Integration via Profinet PROFINET is now the standard in … Read more
Fault Diagnosis When S7-1200 communicates as a DP Master, the CPU does not stop and does not require downloading the organization block when a DP slave is lost. There are several methods for diagnosing faults in PROFIBUS DP: 1. Through the Indicator Lights on the Module The DIAG light on the front panel is green … Read more
