Message Functions
2-122
Note: 1. Even if addresses are within the given device range, they may exceed the range of the device area depending on
the model of the Mitsubishi Q/A-series PLC.
Refer to the following manual for details.
Programmable Controller Manual from Mitsubishi Electric Corporation
2. The corresponding register address in the MP3000 can be adjusted by using the offset setting of the MSG-SNDE
function.
Remote Station Register Type (PARAM16)
This parameter is not used for the A-compatible 1E Frame protocol.
Data Size (PARAM17)
Set the data size for the read/write request as the number of bits or words.
Be sure that the last data address that is determined by the offset, data address, and data size does not
exceed the valid data address range.
The range that is allowed for the data size depends on the function code and data area.
