Appendix G MSG-SND/MSG-RCV Functions (Ethernet)
G.1 Message Transmit Function (MSG-SND)
A-69
( 7 ) Data Address (PARAM05)
Specify the start address of the data.
The address must be input in decimal or hexadecimal numbers.
Example: When the start address is MW01000, specify “1000 (decimal)” or “3E8H (hexadecimal).”
The valid range of usable function codes and data addresses may differ, depending on the device type and device range
of the MELSEC side.
The following table gives the valid ranges of data addresses when using MELSEC as a protocol.
Note: 1. The device range may differ according to the MELSEC sequencer even within the device range. For
more information, refer to the MELSEC manual.
2. The register number corresponding to MP2000 can be adjusted by the offset setting of the MSG-SND
function.
