３．１ Setup of initial setting service
When specifying I/O arrangement information by stypeM of initial setting demand SDU (service data unit)
from master station to OPCN66-Z, a setup of the same n_io_arrM and io_arrM of SDU is coincided with the
setup of J-04 and J-05 of the VF66B inverter setting parameter shown in table3.1 of a front page. When asetup is not coincidence, the RESULT code "initialization directions refusal" is replied as a processing result of
initial setting service of OPCN66-Z. Moreover, when not specifying I/O arrangement information by stypeM,
the number of input words and the number of output words of input/output service apply a setup of J-04 andJ-05, respectively.

３．２ The function using input/output service
By input/output service of OPCN66-Z, transmission of a operation command, reverse command, speedcommand, torque command, and transmission of a multifunctional input signals are made to a VF66B
inverter from master station, and monitors, and a monitor can do operational status, a protection state,current, voltage, etc. of an inverter. Moreover, input/output service of OPCN66-Z can be used as an
input-and-output signal of the built-in PLC function of VF66 inverter. Refer to the description of VF66 PCToolfor a built-in PLC function.
Input/output service of OPCN66-Z supports only the asynchronous method .
To the number of input words and the number of output words of input/output service, a setup of J-04 andJ-05 is applied, respectively.
In the input/output demand SDU which a master station transmits, a setup of len (L), len (H), iosizeM (L), andiosizeM (H) is united with a setup of J-05. Priority is given to a setup of J-05 when these setup does not suit a
setup of J-05.
In the following explanation, the numerical value of the "address" part in Fig. 3.1 is an offset value from thehead address (+13) of iodataM (output data) or iodataS (input data) in the input/output service SDU.

Since all data sizes are 1 word (2 bytes), the byte size of data serves as even number. In the case of odd
number, a part for 1 byte of the last data is disregarded.
2) OPCN66-Z replies the received data to a master office as it is as a data write-in response.
3) OPCN66-Z processes data between VFC66-Z according to instructions of 1), and sets a processing result tothe data readout demand SDU. A S/F bit is set to the 1st word by the success or failure of processing.
4) By data read-out demand, master station transmits demand data, as OPCN66-Z transmits a processing
result5) OPCN66-Z replies the data created by 3) as a data read-out demand.
* The data which OPCN66-Z transmits with data readout service is only a result of the processing
directed with data write-in service in advance. When not correctly directed by data write-in service,
OPCN66-Z answers considering the status part between 7L level of 7 L_hd as "with no slave stationtransmitting data (data transceiver service 2)."Below, readout and the rewriting procedure of setting data of various data are explained separately.
(2) Readout of setting data
The following procedures perform readout of the setting data of VF66B inverter.
1) Master station transmits the data write-in demand shown in figure 3.14 to OPCN66-Z, and directs readoutof setting data, and the number of top setting data, and the total byte size of the data to read. Both of thesetting data, 1st / 2nd setting block, can be read. Since all data sizes are 1 word (2 bytes), the byte size ofdata serves as even number. In the case of odd number, a part for 1 byte of the last data is disregarded.
122 words data can be read at the maximum at once. At this time, byte size directions of 2nd word are set
to 244 [bytes].
* Ask separately about the setting data number of a VF66B inverter.
2) OPCN66-Z replies the received data to a master station as it is as a data write-in response.
3) By data readout demand, as a master office transmits a processing result to OPCN66-Z, it transmits
demand data. The demand data at this time becomes the same as 1).
4) As a data readout demand, OPCN66-Z gives a S/F (success or failure of processing) bit to 1st word, andreplies the setting data read from the inverter (figure 3.15). 122 words setting data is transmitted at the

readout of a protection history. 2nd word byte size directions are 12 [byte] (6 words) fixation.
2) OPCN66-Z replies the received data to a master station as it is as a data write-in response.
3) By data readout demand, as a master office transmits a processing result to OPCN66-Z, it transmits
demand data. The demand data at this time becomes the same as 1).
4) As a data readout demand, OPCN66-Z gives a S/F (success or failure of processing) bit to 1st word, andreplies the protection history data read from the inverter (figure 3.17). 6 words protection history data aretransmitted sequentially from the newest history. The bit configuration of protection history data is shownin table 3.6, and the contents of the protection code are shown in table 3.7. The contents of the protection
history are the same as that of the protection history of the monitor display of a SET66-Z console. Also referto the instructions manual of the main part of VF66 inverter collectively.

(4) Trace back data readout
VF66B inverter memorizes the data of the current, voltage, etc., at the time of protected operation andcontains the trace back function which reads afterwards and can be used for analysis. In order to use a traceback function effectively, it is necessary to set a setting parameter (F area) correctly in the main part of an
inverter beforehand. For details, refer to the instructions manual of the main part of VF66 inverter.
Readout of the trace back data of a VF66B inverter is the following procedures.
1) Master station transmits the data write-in demand shown in figure 3.18 to OPCN66-Z, and directs
readout of trace back data, and trace back data address, and the total byte size of the data to read. Since
all data sizes are 1 word (2 bytes), the byte size of data serves as even number. In the case of odd
number, a part for 1 byte of the last data is disregarded. Moreover, a trace back data address specifies
even number. In the case of odd number, a part for 1 byte of the last address is disregarded. The historyof trace back data can be specified to four in the bits 4 and 5 of 1st word. A setup of a trace back data

Maximum of 100 words data can be read at once. At this time, byte size directions of 2nd word are set
to 200 [bytes].
Correspondence with the channel and an address of trace back data is shown in Table 3.9, and thecontents of data of each channel are shown in Table 3.10. However, ch1-ch12 differ from the contents
shown in a table, when a setup of the inverter setting parameter F-15 to F-26 is not 0. For details, refer tothe instructions manual of the main part of VF66 inverter.
2) OPCN66-Z replies the received data to a master station as it is as a data write-in response.
3) By data readout demand, as a master office transmits a processing result to OPCN66-Z, it transmits
demand data. The demand data at this time becomes the same as 1).
4) As a data readout demand, OPCN66-Z gives a S/F (success or failure of processing) bit to 1st word, andreplies the trace back data and 2 words trigger time information to read from the inverter (figure 3.19).
Keep in mind that 4 bytes increases more than the byte size directed by the above 1). 100 words traceback data is transmitted at the maximum at once.

(5) Monitor Data Read-out
The monitor item displayed on the SET66-Z console of a VF66B inverter can be read.
Readout of the monitor data of a VF66B inverter is the following procedures.
1) Master station transmits the data write-in demand shown in figure 3.20 to OPCN66-Z, and directs
readout of monitor data. Byte size directions of 2nd word are fixation in 50 [a byte] (25 words). OPCN66-Z
replies the received data to a master station as it is as a data write-in response.
2) By data readout demand, as a master office transmits a processing result to OPCN66-Z, it transmits
demand data. The demand data at this time becomes the same as 1).
3) As a data readout demand, OPCN66-Z gives a S/F (success or failure of processing) bit to 1st word, andreplies monitor data(figure 3.19). 25 words monitor data is transmitted at once. The contents of monitor
data are shown in Table 3.13. It is the same as that of the monitor item displayed on a console. For
details, refer to the instructions manual of the main part of VF66 inverter.

(6)Rewriting of setting data
As shown in the following table, the setting data of a VF66B inverter can be protected by rewriting protection
setup. Rewriting protection is not set up in the initial state. Release of rewriting protection is checked before
rewriting of setting data.

Rewriting of setting data of a VF66B inverter is the following procedures.
1) Master station transmits the data write-in demand shown in figure 3.22 to OPCN66-Z, and directs rewriteof setting data, and the number of setting data, and the total byte size of the data to rewrite. Both of thesetting data, 1st / 2nd setting block, can be rewrite. Since all data sizes are 1 word (2 bytes), the byte sizeof data serves as even number. In the case of odd number, a part for 1 byte of the last data is disregarded.
122 words data can be rewrite at the maximum at once.
At this time, byte size directions of 2nd word are set to 244 [bytes].
* Ask separately about the setting data number of a VF66B inverter.
2) OPCN66-Z replies the received data to a master station as it is as a data write-in response.
3) By data readout demand, as a master office transmits a processing result to OPCN66-Z, it transmits
demand data. The demand data at this time becomes the same as 1).
4) As a data readout demand, OPCN66-Z gives a S/F (success or failure of processing) bit to 1st word, andreplies monitor data(figure 3.23). 122 words setting data is transmitted at the maximum at once. Whenrewriting of setting data goes wrong, "FFFFh" is written in the part of the data.
