(b) Click the [OK] button to leave the "Online module change" mode.
(c) Click the [Close] button to close the System monitor screen.
(d) Referring to (1), enable the conversion of the channels to be used, set digital
values to the digital values (Un\G1 to Un\G6), and turn Operating condition setting
request (Y9) from OFF to ON. Turn ON the output enable/disable flag (Y1 to Y6)
of the used channel to check whether proper conversion has been made or not.
(Be careful since analog outputs are provided actually.)
(e) Since the new module is in a default status, it must be initialized by a sequence
program after control resumption.
Before performing initialization, check whether the contents of the initialization
program are correct or not.
1) Normal system configuration
The sequence program should perform initialization on the leading edge of
Module READY (X9) of the Q66DA-G.
When control resumption is executed, Module READY (X0) turns ON and
initialization is performed. (If the sequence program performs initialization only
one scan after RUN, initialization is not performed.)
2) When used on remote I/O network
Insert a user device that will execute initialization at any timing (initialization
request signal) into the sequence program. After control resumption, turn ON
the initialization request signal to perform initialization. (If the sequence
program performs initialization only one scan after a data link start of the
remote I/O network, initialization is not performed.)
