30 External Device Communication – FNC270 to FNC276

→ For the instruction execution complete flag use method, refer to Subsection 6.5.2.

*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

→ 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).

This instruction is applicable to the following inverters: 

- FREQROL-E700 (February 2009 and later)
- FREQROL-D700 (Applicable in all)

→ For details, refer to the respective inverter manual
