7. COMMUNICATION DATA LIST
7.1 Remote Input/Output
Remote input (RX) and Remote output (RY) is ON/OFF data.
“n” in the table is the address assigned to the master station by the station number setting.
It can be calculated by the following equation. However, the computing equation is when a network is
configured only by using our COM-JCs and the number of all Occupied station/Extended cyclic are at
the same setting.
Number of Occupied station
/
Extended cyclic setting
Equation
1 station occupied 1 time n = (Station number*
−
1) × 2
4 stations occupied 1 time n = (Station number*
−
1) × 2
4 stations occupied 2 times n = (Station number*
−
1) × 3.5
* Station number when there is one occupied station: 1 to 64 (each number can be set)
Station number when there are four occupied stations: 1 to 61
(Four stations are occupied for each station
number, and thus only numbers that are
increments of four can be set: 1, 5, 9 …61)
As the calculation result is expressed in decimal number it is converted to hexadecimal number
before substituted for “n” in the table.
Example: When the COM-JC is set to 4 stations occupied 1 time and its station number is 5.
n = (5 − 1) × 2 = 8 (Decimal number) → 8 (Hexadecimal number)
For station number 5: Remote inputs RXn0 to RX (n+7) F → RX80 to RXFF
Remote outputs RYn0 to RY (n+7) F → RY80 to RYFF
If the network consists of COM-JC modules with differing Number of Occupied station/
Extended cyclic settings, use for “n” the total of the highest digits of the number of assigned
registers with station number lower than the module’s own station in order from the lowest
station number.

Number of assigned registers
1 station occupied 1 time 20H (Hexadecimal number)
4 stations occupied 1 time 80H (Hexadecimal number)
4 stations occupied 2 times E0H (Hexadecimal number)
Example: Calculation of “n” when the network consists of three COM-JC modules and the
station numbers and Number of Occupied station/Extended cyclic settings are as
shown below.
1st module [Station number 1]: 4 stations occupied 2 times
n = 0 (No station numbers less than the module’s own station, thus 0)
Remote inputs: RXn0 to RX (n+D) F → RX00 to RXDF
Remote outputs: RYn0 to RY (n+D) F → RY00 to RYDF
2nd module [Station number 5]: 1 station occupied 1 time
n = E (Highest digit of E0H, the number of assigned registers of station 1)
Remote inputs: RXn0 to RX (n+1) F → RXE0 to RXFF
Remote outputs: RYn0 to RY (n+1) F → RYE0 to RYFF
3rd module [Station number 6]: 4 stations occupied 1 time
n = E + 2 = 10
(Total of highest digits of E0H and 20H, the number of assigned
registers of station 1 and station 5)
Remote inputs: RXn0 to RX (n+7) F → RX100 to RX17F
Remote outputs: RYn0 to RY (n+7) F → RY100 to RY17F
“Device address from 1 to 31” in the table correspond to controller device address.
