7 Digital I/O Slave Unit
7 - 8 GX-series EtherCAT Slave Unit User’s Manual
Note that when this function is used, the timing when the contact actually turns ON (or OFF) is
delayed for the set time (ON delay time).
The ON delay time is expressed by "input delay time (time required to read input) + input filter time."
Moreover, if the input filter is used for the Expansion Units as well, the ON delay time becomes
longer because the input delay time is longer than when only Slave Unit is used.
The settings are made using the SDO communication.
The target index is 3000 hex.
For the set values, refer to the information in the corresponding index of "Appendix A-1 Object
Dictionary" in Page A - 34.
 Purpose
This function provides selection whether to hold or clear the outputs if signals from the EtherCAT
Master Unit cannot be received any longer due to communications errors.
 Applicable Slave Unit
Slave Units with digital outputs and Expansion Units (GX-ODxxxx, GX-OC1601, output section of
GX-MDxxxx, XWT-ODxx (
−
1))
 Details of functions
Sets whether to hold or clear the output at communications errors.
It is possible to make setting for each contact. (Default setting: Clear all outputs)
The settings are made using the SDO communication.
The target index is set as follows according to the number of outputs of a single Slave Unit (including
Expansion Units mounted).
For the set value, refer to the information of the corresponding index of "Appendix A-1 Object
Dictionary" in Page A - 40.
