Ethernet Communications
Function Code: 434D Hex
Function: Reads data from multiple registers specified by a 32-bit address, one point at a time.
Data is read one or two words at a time from registers in the remote station as specified in the
remote station address table that is stored in registers in the local station. This function reads the
number of data items that is specified in the data size parameter.
The register to read from in the remote station is listed in the remote station address table.
The following parameters need to be set in the MSG-SNDE function.
1. If the data relay offset parameters in the MSG-RCVE function are set to a non-zero value, the actual
addresses that are written to in the remote station will be the sum of the remote station data
addresses and the word offset value in the data relay offset parameters.
2. Set the address of the registers to write to within the range specified by the G Register Writing
Range Low and G Register Writing Range High parameters in the MSG-RCVE function. Data will
not be written if an address exceeds the valid setting range.
