Settings dialog box. The command size calculation methods are as follows.
■ OK
Save the settings.
■ Cancel

BCC: Displays the specified data enclosed in BCC ( ).
BCC(Calculation Start Position Calculation End Position Calculation Type
Conversion Type Number of bytes)
Calculation Start Position:
Displays the data position where the BCC calculation
starts.
Calculation End Position:
Displays the data position where the BCC calculation ends.
Calculation Type: Display the methods to calculate the data between the
Calculation Start Position and Calculation End Position as
follows.
XOR: When XOR is selected
ADD: When ADD is selected
ADD2: When ADD (2's Complement) is selected
Conversion Type: Display the conversion methods for values of devices as
follows.
B16-A: When Binary (HEX) to ASCII is selected
N: When No Conversion is selected
Number of bytes: Displays the number of bytes of the transmitted or
received data.
Example: BCC(2 1 XOR N 2)
Skip: Displays the specified data enclosed in Skip( ).
Skip(Number of bytes)
Example: Skip(2)
Edit Add or change data.

Up Shifts the selected data upward in the command.
Down Shifts the selected data downward in the command.
TXD: Number of bytes for Constant Data + Number of bytes for a data of Registering Constant + Number of
bytes of BCC + Number of bytes of Device x Words of Device
RXD: Number of bytes for Constant Data + Number of bytes for a data of Registering Constant + Number of
bytes of BCC + Number of bytes of Skip + Number of bytes of Device x Words of Device
