Wide (N=3) communication

Figure 2.37-5 shows the Wide frames in the IEEE C37.94 standard as N=3†. When Wide is

applied, sub-communication channels are provided at bits: COM1(2bits), COM2(2bits),

COM3(2bits), COM4(2bits), and COM6(6bits).

†Note: Set Wide for scheme switch [CH*_COM_WIDTH]. For more information, see

‡Note: Three bits in the COM5 (1–3) are pre-assigned for sending signals "CBDS-A,-B,-

Integral communication bits

When On is set for setting [DIFGL-EN]†, zero-sequence current data 'I 0 'will be sent to the

remote end using the integral channel spaces (ICOM1—4) in the communion frame. If Off is

set, the ICOM1—4 space will not be used during the communication. Therefore, the user can

use those spaces for user's PLC data.
