*1: Mode selection is performed using network parameters.
*2: The number of LY points of the stations set in the I/O master station is the sum total of the
LY points for output to all stations within the block.
*3: This value is set as default of the communication speed.
*4: For details of cable specifications, refer to Section 5.1 or Section 5.2 in this manual.
For general specifications of the network module, refer to the user's manual for the CPU used.
