Overview
This chapter describes gives an overview, limitations, applicable models, applicable PLCs, and setting parameters of the
PLC connection.
1. 1 PLC connection
The PLC connection is a device in which the read result of barcodes is directly written to the data memory of a PLC (Pro-
grammable Logic Controller).
The WB1F supports the PLC communication protocol, and there is no need to create a specic communication program
in the PLC.

What is data memory?
It is the general storage area incorporated in PLC, allowing read and write.
The data exchange between the WB1F and PLC uses data memory.
The name and size corresponding to the data memory depends on the PLC.
For details, refer to F[3 Setting and Wiring] on page 3-1.

Setting Parameters (WB1F)
1. 5 Setting Parameters (WB1F)
The setting parameters and setting values necessary for the PLC connection are as follows:
Adjust the setting according to the using environment.
zAll the settings of the WB1F should be performed before using the PLC connection.
zWhen the device of setting the WB1F (as PC) is dierent from the device to be connected through the PLC
connection, prepare a cable supporting both devices.
zDo not access or change any settings that are not listed here.
zDo not access or change any settings in reserved areas.
zWhen the setting values have been changed, save the setting value by “Save Set Values”on the control com-
mand.
Turning OFF the power, resetting, or changing the operation mode without performing “Save Set Values”will
return to the setting value that existed before change.
When conguring settings that specify ASCII code for the setting value, be aware of the following points.
zNUL (00H) cannot be used as a setting value.
zThe characters up to the rst NUL (00H) are considered the data and any data after that is not valid.
Setting value (hex) of bold face is default value (Setting at the time of factory shipments).

Operation Specications
This chapter describes the operation specication of the PLC connection.
2. 1 Overview
The WB1F periodically reads the PLC data memory. When the data memory which is being read has any change, the func-
tion assigned to the data memory is performed.
This mechanism allows to perform each function of the WB1F only by setting the data memory of PLC to the specied
value.
2. 2 Assigning Data Memory
The WB1F performs reading and writing to the “Special area” and the “Scanner Information Area” assigned to the PLC data
memory. When using this function, set where to assign these two areas in the data memory. For details of the setting, refer
to F[1. 5 Setting Parameters (WB1F)] on page 1-3.

Special Area
2. 3 Special Area
With the special memory area starting address as a header, the following functions shown in the table below are assigned
to the data memory.By setting the corresponding bit of the correspoding address to “1”, each function can be performed.
The WB1F performs the requested function, and then performs zero clear of the special area.
The zero clear after the function is executed targets not only the corresponding bit of the corresponding address, but the
special area entirely.

Special Area
When multiple bits are set to 1 at the same time, the lowest one is preferably executed for both address and bit. The other
functions are ignored.
e.g. When the following thee bits are set to 1 at the same time:
z[Bit 8 of Address 0]
z[Bit 9 of Address 0]
z[Bit 0 of Address 1]
The function only assigned to Bit 8 of Address 0 is executed.
e.g. When the following three bits are set to 1 at the same time:
z[Bit 0 of Address 0]
z[Bit 9 of Address 0]
z[Bit 0 of Address 1]
The function only assigned to Bit 0 of Address 0 is executed.

Start and End
2. 5 Start and End
The PLC connection can be started and ended in the following conditions:
Start condition
With Address “06C0 (PLC connection – function Enabled) in the setting parameter of the WB1F set and stored to ”01 (En-
able), turn the power from OFF to ON.
When the start condition is established, the Indicator LED (Green) starts ashing.
After blinking stops, the PLC connection starts.
End condition
zDepress the Operation button of the WB1F for 5 seconds.
zSet the PLC Connection End Bit in the Special Area of the PLC data memory to “1”.
When the end condition is established, the Indicator LED (Red) starts blinking.
After blinking stops, the PLC connection ends.

Operation Sequence
2. 6 Operation Sequence
The WB1F repeatedly performs the following four operations:
1 When barcode reading is completed, the writing of barcode data to the scanner information area is performed.
2 When the execution of the requested function is completed, the zero clear of the special area is performed.
3 When the bit in the special area is 1, and there is a request of function execution, the assigned function is per-
formed.
4 If the above 1 to 3 is not applicable, reading of the special area is performed.

When creating a PLC program, note the following:
(1) After checking that the special area is all “0”, make the bit in the special area to ”1”.
(On the PLC program, even when the dierent bit is 1 in the dierent timing, it is regarded that plural bits
are set to 1 at the same time depending on the communication timing.)
(2) Before requesting to start reading the barcode, perform zero clear for the scanner information area (data
length).
(3) If the connection between the WB1F and PLC cannot be established after the specied times of retry, the
process is transferred to the “Special Area Read”.
(4) When the bit in the special area is “1” when the communication is restored, the corresponding function is
performed.
(Even for the function requested by the PLC program before the communication was unsuccessful, when
the bit in the special area is “1” when the communication is established, the function is performed.)

MC Protocol Connection
3. 2 MC Protocol Connection
3. 2. 1 Overview
The MC protocol performs data sending/receiving between the WB1F and the MELSEC sequencer.
The MC protocol is the abbreviation of “MELSEC Communication Protocol,” which is the communication protocol for the
MELSEC sequencer allowing the sequencer to communicate with external devices (such as the WB1F)
The WB1F can send/receive the data to/from the MC protocol supporting devices in the following conditions:
Protocol Format 4, 4C frame, Check sum
Series supported *1 MELSEC iQ-R/iQ-F/Q/L series
Connection method RS-232
Data memory Data register
*1 For the details of supporting devices, refer to F[1. 4 Applicable PLC] on page 1-2.
3. 2. 2 WB1F Setting examples
To perform the data send/receive with the MELSEC sequencer, the setting of the RS-232 of the WB1F as well as the PLC
connection is necessary.
When selecting the MC protocol, the protocol parameters [0]to [15] means the following setting respecitvely.
Protocol Parameter [0] Station No.
Protocol Parameter [1] Network No.
Protocol Parameter [2] PC No.
Protocol Parameter [3] I/O No. of the unit requested
