Weight
*1 Transmission speed control within +/- 0.3% (PROFIBUS part 1)
*2 Distance that the transmission distance can be expanded by (m/network) using repeaters
Maximum transmission distance (m/network) = (number of repeaters + 1) × transmission distance (m/segment)
*3 The *3 restriction will cease to exist when the system is configured exclusively by the master and slave stations of
the hardware version B or later versions.
Point
*3 When using 12Mbps transmission speed, restriction of the cable length and the number of connector stations
described below is necessary.
1) Minimum length of the cable between stations is greater than or equal to one meter.
2) Maximum number of the connection stations are smaller than or equal to 11.
