1.2 System Configuration
The remote I/O system [MEWNET-F] is a network which can be configured with master stations (CPU
unit + master unit) and slave stations (slave unit + I/O unit or various remote I/O exclusive I/O terminal)
with transmission cables (two-wire cable). The CPU unit of master station controls the I/O (remote I/O)
slave stations via the master unit.
*You can connect various kinds of slave stations on a single communication path from a master unit.
For example, the FP2 master unit can be connected to an FP3 slave unit and I/O terminal unit.
Configuration requirements
No. of installed master units per CPU unit
Max. 4 units
No. of slave stations per master unit
Max. 32 stations
No. of controllable I/O points per master unit
Note1)
Max. 4096 points
No. of controllable slots per CPU unit
Max. 128 slots
No. of controllable slots per master unit
Max. 64 slots
Transmission cable (Two-wire cable)
VCTF 0.75 mm
2
x 2C (JIS) or equivalent
Total transmission distance per port
Note2)
Max. 700 m
Note1) It vaires according to the number of maximum cotrollable I/O points of CPU unit.
Note2) The transmission distance varies according to the used cable and type of unit.
