4. Using Optical/Electrical Conversion Modules
1) Number of Modules
Optical/Electrical Conversion Modules are used in combination with the following Mod-
ules. Restrictions do not apply to the number of Optical/Electrical Conversion Modules
that can be used independently.
a) Optical/Electrical Conversion Modules can be combined with PC Link Modules to
form Optical PC Link systems.
b) Optical/Electrical Conversion Modules can be combined with Remote I/O Driver Mod-
ules and Remote I/O Receiver Modules to form Optical Remote I/O systems.
2) Installation Location
An Optical/Electrical Conversion Module can be mounted to any slot of the Mounting
Base of any Rack. It will occupy one slot.
3) Electrical Ports
a) With PC Link Modules
Optical/Electrical Conversion Modules used in combination with PC Link Modules en-
able high-speed communications via electrical ports at a baud rate of 4 Mbps with up
to 31 Optical/Electrical Conversion Modules. The transmission distance depends on
the baud rate and coaxial cable used. If, for example, the baud rate is set to 4 Mbps
and 12C-5AF communications cables are used, it is possible to transmit up to 1 km.
b) With Remote I/O Modules
Optical/Electrical Conversion Modules used in combination with Remote I/O Driver
Modules and Remote I/O Receiver Modules enable high-speed communications via
electrical ports at a baud rate of 4 Mbps with up to 15 Optical/Electrical Conversion
Modules. The transmission distance depends on the baud rate and coaxial cable
used. If, for example, the baud rate is set to 4 Mbps and 12C-5AF communications
cables are used, it is possible to transmit up to 1 km.
4) Optical Ports
a) With PC Link Modules
Optical/Electrical Conversion Modules used in combination with PC Link Modules en-
able high-speed communications via optical ports at a baud rate of 4 Mbps with up to
31 Optical/Electrical Conversion Modules. The transmission distance depends on the
connection method and the optical fiber cable used. If, for example, the baud rate is
set to 4 Mbps and quartz crystal cables are used, it is possible to transmit up to 12 km
in total (2 km between stations).
b) With Remote I/O Modules
Optical/Electrical Conversion Modules used in combination with Remote I/O Driver
