15 EXTERNAL DEVICE COMMUNICATION INSTRUCTION
15.2 Inverter Communication Instruction
833
15
Precautions
• If a device number outside the range due to indexing, etc. is specified in (d1), the receive data from the inverter is not stored
in (d1). However, values set in (s3) and (s3)+1 may be written to the inverter.
• If any unspecified value is set in (s2), unexpected data may be written to and read from the inverter, and values of (d1) and
(d1)+1 may be updated.
• The IVMC instruction reads the inverter status at the time of communication with the inverter, and stores it in (d1).
Accordingly, the inverter status written by the IVMC instruction can be read when the next reading instruction (IVCK, IVMC,
etc.) is executed.
• Two devices are occupied from the device specified in (s3) and (d1). Make sure that these devices are not used in other
controls.
• Three devices are occupied from the device specified in (d2). Make sure that these devices are not used in other controls.
