of the control station and normal stations on the network.
• When the control station is in the MELSECNET/H Extended
mode
0: Set to the MELSECNET/H Extended mode. (Including
stations of station Nos. greater than the maximum, reserved
stations and communication error stations)
1: Set to the MELSECNET/H mode or MELSECNET/10 mode.
• When the control station is in the MELSECNET/H mode or
MELSECNET/10 mode
0: Set to the MELSECNET/H mode or MELSECNET/10 mode.
(Including stations of station Nos. greater than the maximum,
reserved stations and communication error stations)
