Function and operation explanation
→ For detailed explanation of the instruction, refer to the Data Communication Edition manual.
1. 16-bit operation (IVBWR)
A data table (parameter numbers and set values) specified in and is written to an inverter
*1
connected to a communication port n whose station number is in the device specified by all at once.
*1. Mitsubishi Electric's FREQROL - F700, A700, E700, D700, V500, F500, A500, E500 and S500 series
general purpose inverters
*2. The table below shows the data table format.
: Number of parameters to be written
: Head device number of data table

*1. Cleared when the PLC mode switches from STOP to RUN.
*2. Initial value: -1
Cautions
→ For other cautions, refer to the Data Communication Edition manual.
1) It is not permitted to use the RS and RS2 instructions and an inverter communication instruction (IVCK,
IVDR, IVRD, IVWR and IVBWR) for the same port.
2) Two or more inverter communication instructions (IVCK, IVDR, IVRD, IVWR and IVBWR) can be driven
for the same port at the same time.
