RFM(Reflective Memory)
The GE high-speed PLC communication scheme is typical. It is same for VxWorks as the kernel of real-time operating system, such as CoDeSys, ISaGRAF, LogiCAD, etc... PLC Manufacturer is VAI, SMS, GE, Westinghouse, etc. The data source type for reading data blocks from the starting address is 11; Dozens of PLC data can be collected at the same time. The total number of sampling points is not less than 10000 points. The sampling period is not more than 2 milliseconds. The data source type for reading data at each variable address is 67. 16.1
Preparation of PLC data
PLC writes data block into reflective memory by "VMEWRITE", real boolean and string are supported, Digital points is 32 times, the necessary byte swap function is in PLC. It is proposed to define a data structure, a certain number of points are reserved for standby, and once the data block is written into the reflective memory whose address has been allocated for PDA anteriorly. 16.2
The PDA server hardware installation
Reflective memory card Rfm5565 and Rfm5576 are supported, there are multiple domestic manufactures producing compatible network cards of the same type.
