■ OUTPUT DATA

The gure below shows the allocation of the data sent from

the network module to the master.

■ INPUT DATA

The gure below shows the allocation of the data sent from

the master to the network module.

Use the DIP SW located at the side of the module to specify expanded cyclic setting. 16 words input and 16 words output

make 1 cyclic. Max. 8 cyclic (128 words input, 128 words output) transmission is available. 1 cyclic is equivalent to 1 I/O

module (analog input 16 points, analog output 16 points). Max. 8 I/O modules can be assigned to 8 slots.

Note: Do not mount any modules in the slots which are occupied by virtual modules. If a real I/O module is mounted in the

slot, an internal bus error occurs and the ERR LED turns on. Max. 16 real I/O modules and virtual modules are available.

The interface module can not read the data for more than 16 modules.

■ WHEN R3-GC1 IS MOUNTED ON SLOT NO. 2 (4 CYCLIC)

Real I/O modules are mounted on Slots No. 1 and 2, however, the network module (R3-NE1) recognizes that each of Slots No. 1

to 5 is occupied. That is, R3-NE1 recognizes R3-SV4 mounted on Slot No.1 as it is and recognizes R3-GC1 mounted on Slot No.2

as divided into four modules and occupying Slots No. 2 to 5.
