What bus communication protocols does Siemens 1500 support?

1500 not only supports a variety of Ethernet communications, but also supports serial port communications, OPC communications, and WEB access.

Siemens PLCs have four major categories and dozens of models. Different PLCs support different communication protocols. The protocols supported by the S7-200 series are: PPI, MPI, PROFIBUS, Ethernet, S7 protocol, AS-INTERFACE, USS, MODBUS, and free port. The protocols supported by the S7-300\400 series include: MPI, PROFIBUS, ETHERNET, ISO protocol, ISO-ON-TCP, MODBUS, etc. The similarity is that the physical transmission medium is the same for the same protocol. For example, the S7 protocol can use DP and Ethernet as transmission media. The difference is that each protocol corresponds to different configuration methods and procedures.

S7 communication is used between 1500 and 1200. The general steps are as follows: 1. First add a 1500 device, then add a 1200 device, and select S7 connection. Please be careful not to set a password during the process. , allowing PUT/GET access. 2. In the program, add S7 communication instructions. The GET instruction is to receive partner data, and the PUT is to send data to the partner. For example, if 1500 wants to receive 1200 data, use the GET instruction. Otherwise, if you want to send data to 1200, use the PUT instruction.
