ONLINE MODULE CHANGE
(d) Enable the conversion of the channel to be used in Conversion enable/disable
setting (Un\G0), and turn Operating condition setting request (Y9) from OFF to
ON. Monitor CH Measured temperature value (Un\G11 to Un\G18) to check if
the conversion is processed normally.
(e) Since the new module is in a default state, initial setting must be performed by a
sequence program after the restart of control.
Before performing initial setting, check that the contents of an initial setting
program are correct.
1) When a module is used in normal system configuration
Create a sequence program so that initial setting is performed on the rising
edge of Module ready (X9) of the Q68RD3-G.
When control is restarted, Module ready (X0) turns ON and initial setting is
performed. (If the sequence program performs initial setting only for one scan
after RUN, initial setting will not be performed.)
2) When a module is used on remote I/O network
Insert a user device that will perform initial setting at any timing (Initial setting
request signal) into a sequence program. After the restart of control, turn ON
Initial setting request signal to perform initial setting. (If the sequence program
performs initial setting only for one scan after a data link start of the remote I/O
network, initial setting will not be performed.)
(5) Restarting control
(a) Display the "Online module change" screen again from the screen displayed by
selecting [Diagnosis] - [Online module change] in GX Developer and click the
button to restart control. Module ready (X0) turns on.
(b) The following screen appears.
