FUNCTIONS

■ WIRE BREAKDOWN DETECTION
The function to notifies to the status bit of upper input area in case of open load (disconnection) of discrete output is detected.
Connect output load under 10 kΩ.
Pull-down resister is mounted to detect disconnection so weak leakage current flows even when the output is OFF.
Status bit is disabled and pull-down resister is not mounted with option code: /D1 (withourt wire breakdown detection).

PC CONFIGURATOR

The following parameters can be set with using PC Configurator Software (model: R7CFG)
Refer to the users manual for the R7CFG for detailed operation of the software program.

TERMINAL ASSIGNMENTS

■OUTPUT TERMINAL ASSIGNMENT

RESPONSE TIME

Response time of discrete output module is the time till when the module output the signal from when output data is received by the communication ASIC of the module.
TCOM: MECHATROLINK-III transmission cycle set at master
(depends on system and configuration)

TOUT: Response of output module ≤ Output internal processing delay time (Td, one minimum transmission cycle the unit can handle) + Conversion time (Te) + Delay of output circuit (Tf, ON delay time or OFF delay time)

E.g. 2: MECHATROLINK-III transmission cycle: 0.5 msec., discrete output OFF
Response of output module (T0UT): Output internal processing delay time (0.125 msec.) + Delay of output circuit (0.5 msec.) 
= 0.625 [msec.]

I/O DATA DESCRIPTIONS

When overcurrent or overheat is detected on each channel of discrete output while the output is ON, the status bit corresponding to the output turns “1” and is latched*. Then the discrete output is also latched to OFF.
To reset the latched bit and discrete output, set this output to OFF from the host PC/PLC or turn off and on the power supply to the unit.
When disconnection (open load) is detected while output is OFF, the corresponding status bit turns “1” but is not latched.
* The status bit turns “0” if the load is opened in the state overcurrent or overheat is detected. However, the discrete output of the unit remains latched. Be sure to remove the cause of error and reset the latched output by setting the output to OFF or turning off/on the power supply
