9.11.5 Example in which the point mode setting causes an invalid configuration
1. Configuration
When CL1XY2-DT1D5S (cable type remote I/O unit having 1 input point and 1 output point) x 63 units (station
No.s 1 to 63) and CL2X8-D1B2 (terminal block type remote I/O unit having 8 input points) x 1 unit are
connected
Configuration applicability for each point mode
• In 16-point mode...........The system can be constructed.
• In 4-point mode.............The system cannot be constructed since the CL2X8-D1B2 occupies 2 stations
and the number of remote stations exceeds 64.
2. The example of assignment of the I/O numbers
The I/O number assignment is as follows in the configuration example below.
Set the built-in master to CONFIG mode, and turn ON the power of the PLC. Connected remote stations are
automatically checked, and I/O numbers are assigned to each remote station.
Point mode and Number of stations
Unused numbers in I/O extension
The above I/O numbers are assigned as follows in the configuration example.
