*1. Cleared when PLC power supply is turned from OFF to ON.
*2. Cleared when the PLC mode switches from STOP to RUN.
*3. Initial value: -1
Cautions
→ For other cautions, refer to the Data Communication Edition manual.
• It is not permitted to use an "RS (FNC 80)/RS2 (FNC 87)"/"ADPRW (FNC276)"/"FLCRT (FNC300) to FLSTRD
(FNC305)" instruction and an "IVCK (FNC270) to IVMC (FNC275)" instruction for the same port.
• Two or more inverter communication instructions (FNC270 to FNC275) can be driven for the same port at the same
time.
• Number of occupied devices
Two devices are occupied respectively by and .
Make sure not to use those devices in another control.
• If a device number outside the range due to indexing, etc. is specified in , the receive data from the inverter
is not stored in . However, values set in and +1 may be written to the inverter.
• If any unspecified value is set in , unexpected data may be written to and read from the inverter, and values
of and +1 may be updated.
• IVMC instruction reads the inverter status at the time of communication with the inverter, and stores the read status
to . Accordingly, the status written by the IVMC instruction can be read by a next or later read instruction
(IVCK or IVMC).
