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.

RESPONSE TIME
• Input module
Response time is time from when a step (0 to 100%) input signal is applied to the input module (slave) until when output from its communication CPU reaches 90% of the final value.
• Output module
Response time is time from when a step (0 to 100%) output signal is received by the communication CPU of the output module (slave) until when its output reaches 90% of the final value.
T
COM
: EtherCAT communication cycle set by the host device (master)
(The cycle is determined in accordance with the system configuration and settings.)
T
INP
: Input module response time ≤ Delay time of input circuit (Ta) + read cycle (Tb) + Input internal processing time (Tc) (Communication cycle x 2)
T
OUT
: Output module response time ≤ Delay time of output internal processing (Td) (communication cycle x 1) + 0 msec. (Te) + Delay time of output circuit (Tf)
ex.) When EtherCAT communication cycle: 1 msec. and delay time of output: ON,
Input module response time (T
INP
): Delay time of input circuit (0.5 msec.) + Read time (1 msec.) + Input internal processing time (1 msec. x 2) = 3.5 [msec.]
Output module responce time(T
OUT
): Delay time of output internal processing (1 msec.) (communication cycle x 1) + 0 msec. + Delay time of output circuit (0.2 msec.) = 1.2 [msec.]
