Communication Setting
The recommended communication parameter settings of the PLC and the V7 series is as follows:
* The maximum baud rate available with the V7 series is 115200 bps.
Select the appropriate baud rate depending on the used PLC and environment.
V-SFT Setting
Set [Trans. Mode] in the [Detail] tab window of the [Comm. Parameter] dialog of the V-SFT
editor.
*1 BCD w/ signs
Data in the PLC memory can be shown as data with signs.
When higher 4 bits in the memory indicates [F] or [A], it is treated as negative.
[F]: Regards higher 4 bits as [
−
0].
[A]: Regards higher 4 bits as [
−
1].
