Contact health check
(iv)
The SPOS01 function has contact health check feature for the BO circuits; hence, the user is
able to connect an output signal to the contact health check function when Fixedlogic is set for
scheme switch [SPOS01-LGXFEOT]†. Consequently, the SPOS01 function can determine
whether the signal has been successfully output from the BO. If a failure is reported, the
SPOS01 function determines that the signal has not been output successfully to the BO; then,
the command On or Off is canceled immediately and the SPOS01 function returns to the "Wait
for a command" stage.
†Note: Table 4.1-29 shows settings for the health check feature in the other SPOS
functions.
Setting for "Select command On/Off"
For example, the point "SPOS01_SL_BO_FLG" is connected to the BO1 circuit for the issuing
of the command, the user can connect point "BO1-RB" with the contact health check function
using the setting [SPOS01-SLBORD]. Do not key the point "SPOS01_SL_BO_FLG".
