(2) Cable performance comparisons
(a) Optical fiber cable
1) Overall distance
The overall distance (30km) does not differ according to the optical fiber cable.
2) Distance between stations
• SI optical fiber cable
: Compatible, : Partial change required, × : Incompatible
*1 When the distance between stations do not satisfy with specifications of MELSECNET/H, use at 10 Mbps of communication
speed, change the type of optical fiber cable or set the gateway station on the existing cable.
• GI optical fiber cable
: Compatible, : Partial change required, × : Incompatible
(3) Coaxial cable
(a) Overall distance
: Compatible, : Partial change required, × : Incompatible
*1 When the overall distance does not satisfy the MELSECNET/H specifications, either use an A6BR10/A6BR10-DC type
repeater unit in the network, or configure a separate network.
(b) Distance between stations
: Compatible, : Partial change required, × : Incompatible
