FLAGS

Input

Flag (the same as 0735. Refer to the following table for the details.)

 

 

 

 

 

 

 

 

 

 

 

TIMER

Output

Communication monitoring time 001(D) (0.1 second) to 255(D) (25.5

 

 

seconds) (Initial value 000(D) is 1 second.)

G (7th bit)

Output

Starting instruction. Turn ON after starting communication.

TYPE

Output

 

 

 

 

01(H) : SEND (two hierarchical layer differences),

 

(0 bit to 6th bit)

 

 

 

 

 

02(H) : RCV (one hierarchical layer),

ST1

Output

For cases with one hierarchical layer, the number of the target station

 

 

is 00 to 77(8). For cases with two hierarchical layer differences, the

 

 

number of the relay station is 00 to 77(8).

 

 

 

 

 

 

 

 

 

 

 

R_SL

Output

For cases with two hierarchical layer differences, the module number

 

 

of the next hierarchical layer difference in relay station. (When the relay

 

 

station is JW50/70/100 or JW50H/70H/100H, it represents the rack/

 

 

slot number.) For cases with one hierarchical layer difference, invalid.

 

 

 

 

 

 

 

 

 

 

 

ST2

Output

For cases with two hierarchical layer differences, the number of the

 

 

target station is 00 to 77(8). For cases with one hierarchical layer

 

 

difference, invalid.

 

 

 

 

 

 

 

 

 

 

 

n

Output

Number of transfer bytes 000 to 377(8) (000(8) is 256 bytes)
