DESCRIPTIONS

■ RUN Contact (LED) Behaviors

Input units

Input units (A1, A2, G1 and P1): The LED turns ON with the network built-up; OFF in error; the network is reconfigured after an

error.

•Connecting the input unit to the DLC

The LED remains ON regardless of the input command of the DLC.

Output units

Output units (C1, C2, C3, C4, M1 and U1): The LED turns ON when data from the paired input unit is received normally, with the

network configured; OFF when the data is lost; turns also OFF in error in the network.

Transmission via the DLS units: The LED remains ON regardless of the input unit status or telecomm. line status, once it is

turned ON.

•Connecting the output unit to the DLC

After the output unit receives the output command from the DLC, the LED turns ON and remains ON regardless of the data

update.

I/O-mixed units (E1, E2, R1 and S1): The LED turns ON when data from the paired input unit is received normally, with the

network configured; OFF in case of data loss or network error.

•Connecting the I/O-mixed unit to the DLC

After the I/O unit receives the output command from the DLC regardless whether input or output, the LED turns ON and

remains ON regardless of the data update.

[CAUTION]

When the network is reconfigured e.g. by noise interference, the RUN LED and output for all units on the network turn briefly

OFF until they are turned ON after the reconfiguration is complete.

■ Station Number (Address)

A) 1 input unit and X output units: Match the address for input and output units. The input data can be output at several units.

A 64-point input unit needs two station numbers. Do not assign the number following the one set for a 64-point input unit to

another unit.

B) 64-point contact input unit to 32-point output units: Match the number for input and one output units, then set a consecutive

number for the other output unit.

[example]

input unit → 01

output unit → 01 & 02

C) 32-point contact input units to 64-point output unit: Match the number for the output and one input units, then set a

consecutive number for the other input unit.

[example]

input unit → 01 & 02

output unit → 01

D) I/O mixed units: Set an even number and a consecutive number for the 2 corresponding units.

[example] 02 & 03

A combination of 3 units or more is not allowed.

E) Computer interface: Set address numbers to correspond with the computer as I/O unit.

■ Transmission Time

Integrate all the transmission time for each process input unit in the system.

•Contact input 32 points (A1): 1.5 msec.

•Contact input 64 points (A2): 3.0 msec.

•Contact I/O each 16 points (E1): 1.5 msec.

•Analog input 32 points (G1): 48.0 msec.

•Analog/pulse Input each 16 points (P1): 48.0 msec.

•Analog I/O each 16 points (R1): 24.0 msec.

•Analog & contact I/O each 8 points (S1): 12.0 msec.

An analog unit does not transmit all its points in serial but does 1 point per each cycle. For example, when 1 contact input unit

and 1 analog input unit (32 points for each) are connected, 32 point contact signal and 1 point analog signal are transmitted in
