CPU Rack with Optical Master
Repeater Unit RPT01-(P) must be used when the number of Optical Slave Racks, Optical Transmitting I/O Units, I/O Link Units, and Link Adapters con- nected in series exceeds 32. Insert a Repeater Unit between the 32nd and 33rd Units. The example below shows an Optical Slave Rack and Optical Transmit- ting I/O Units connected in series. Note that a Repeater Unit is inserted after the total of these Units reaches 32. When I/O Link Units or Link Adapters AL002-(P)E, AL005-(P)E or AL006-(P)E are used, each of them must also be counted as one of the 32 Units.
