TRANSMISSION DATA DESCRIPTIONS
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.
