Appendix 4 Ladder Transfer Function App4-5
How to check the COM port setting for the PLC
To see which port must be set for [COM port] in the [Ladder Transfer Setting] dialog, go to the following dialog provided in the
PLC ladder software.

Notes
•
The ladder transfer function can be used with PLC1. It cannot be used with PLC2.
•
On-line editing between the editor and the S8 series is not possible. If attempted, communications between the PLC
programming software and the PLC will not be performed correctly.

and the S8 series

Baud rate setting
The [Baud Rate] setting in the [Communication Setting] tab window applies to the baud rate between the S8 series and
the PLC. However, if communication with the PLC programming software (monitoring, etc.) starts by means of the ladder
transfer function, the baud rate set on the software takes effect. The baud rate stays enabled until the S8 series is turned
off and on again. Keeping this in mind, set the PLC programming software baud rate and the [Baud Rate] setting in the
[Communication Setting] tab window to the same value.
•
With [Use Ladder Tool] checked, it is prohibited to register the devices to be monitored for S8-PLC communication even
though the PLC programming software is not started. The screen display speed will decrease somewhat accordingly.
•
When the ladder program is transferred in the RUN mode of the S8 series, communications are synchronized; therefore,
the performance of both the S8 series and the PLC programming software decreases.
•
Ladder transfer is possible only in the RUN mode. When transferring the screen data, be sure to display the Main Menu
screen on the S8 series.
•
When [ COM port] is checked, every serial communication that uses the COM port you selected will be converted to
communication via USB. Therefore, be sure that the COM port selected under [COM port] is not already used for other
serial communications. Except when ladder transfer via USB is used, uncheck the box for [
COM port].
