7 ONLINE MODULE CHANGE

(e) Turn User range writing request (YA) from off to on to restore the user set
values to the module.
After confirming that Offset/gain setting mode flag (XA) is on, turn off User
range writing request (YA).
(f) Set the channels to be used to "A/D conversion enabled" in A/D conversion
enable/disable setting (buffer memory address 0: Un\G0) and turn on or off
Operating condition setting request (Y9). Monitor CH
(buffer memory address 11 to 18: Un\G11 to Un\G18) to check whether
proper conversion has been made or not.
(g) 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 (X0) of the A/D converter module.
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 for
one scan after entering the RUN status, initialization is not performed.)
(5) Resumption of control
(a) After choosing the [Diagnostics] - [Online module change] dialog box on GX
Developer to display the "Online module change" dialog box again, click the
[Execution] button to resume control. Module READY (X0) is turned on.
(b) The "Online module change completed" dialog box appears.
