Serial Communications Boards
Serial Communications Boards are Inner Boards for the CS-series PLCs. One
Board can be installed in the Inner Board slot of a CPU Unit. Two serial ports
are provided for connecting host computers, Programmable Terminals (PTs),
general-purpose external devices, and Programming Devices (excluding Pro-
gramming Consoles). This makes it possible to easily increase the number of
serial ports for a CS-series PLC.
Models
The following two models are available:
Connectable Devices
The following serial communications modes are supported by the Serial Com-
munications Unit: Host Link (SYSMAC WAY) (see note 1), protocol macro,
1:N NT Link (see note 2), no-protocol (see note 1), Modbus-RTU slave (see
note 3), and loopback test modes. The devices shown in the following diagram
can be connected.
