    J A description of the FP3/FP10S MEWNET- TR system The FP3/FP10S MEWNET-TR system is a network system that links FP3/FP10S CPUs and I/O field devices with minimum wiring. The remote I/O control function allows the user to control the I/O information of the I/O units that are connected.

  • Page 9: Features

    An FP3 transmitter master unit can control 128 inputs and 128 outputs. In the FP3 MEWNET-TR system, by connecting sixteen FP3 transmitter master units, remote I/O control of up to 2,048 inputs and 2,048 outputs is possible. In the FP10S MEWNET-TR system, by connecting twenty-four FP3 transmitter master units, remote I/O control of up to 3,072 inputs and 3,072 outputs is possible.
  • Page 10 When the network is connected with twisted pair cable, the maximum transmission distance is 700 m (2,296.59 ft). When a 2-conductor cable is used, the maximum transmission distance is 400 m (1,312.34 ft). Example : FP3/FP10S MEWNET-TR system FP3/FP10S CPU...

    A device that is kept available to replace something that may fail during operation. battery backup: A battery or set of batteries that will provide power to the processor memory only when system power is lost. FP3 CPU, FP10S CPU, and S-RAM type IC cards have a battery backup system. battery low: A condition that exists when the backup battery voltage drops low enough to require battery replacement.
  • Page 139 8-6. Terminology binary: In general, programmable controllers work with binary numbers in one form or another to represent various codes or quantities. The binary number system uses the number 2 as the base and the only allowable symbols are “0” and “1”. There are no 2s, 3s, etc.
