The connection mode and transmission mode are set in [Comm. Parameters] under [System Setting].
(Refer to “1. Before Connecting to PLC.”)
The mode contents are as follows.
•
Connection mode
1 : 1 Used when one host communicates with one V series unit (1 : 1).
1 : n A maximum of 32 V series units are possible to be connected to the host. (Multi-drop
specifications)
•
Transmission mode
There are four transmission modes, depending on whether or not sum check or CR/LF is attached
to the end of transmission and received data, as shown below.
Set whether or not to attach sum check or CR/LF to the end of transmission data.
*
indicates that there is an attachment.
