7 ONLINE MODULE CHANGE (b) MELSEC-Q If the saved buffer memory contents are not yet prerecorded, record them in the following procedure. 1) Make the pass data classification setting (buffer memory address 200: Un\G200). 2) Turn operating condition setting request (Y9) from OFF to ON. 3) Compare the offset/gain values of the industrial shipment settings and user range settings (buffer memory addresses 202 to 233: Un\G202 to Un\G233) with the range reference table. Refer to Section 7.
7 ONLINE MODULE CHANGE (b) MELSEC-Q Click the "Execution" button to enable a module change. If the following error screen appears, the user range cannot be saved. Click the [OK] button, dismount the module as-is, and perform the operation in Section (2)(c) and later. (c) After confirming that the "RUN" LED of the module has turned off, remove the terminal block and dismount the module. POINT Always dismount the module.
7 ONLINE MODULE CHANGE MELSEC-Q (4) Operation check 7 - 33 (a) To make an operation check, click the [Cancel] button to cancel control resumption. (b) Click the [OK] button to leave the "Online module change" mode. (c) Click the [Close] button to close the System monitor screen.

(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.
7 ONLINE MODULE CHANGE MELSEC-Q 7.4 Range Reference Table The range reference tables are given below. (1) Reference table for offset/gain values of industrial shipment settings (buffer memory addresses 202 to 217: Un\G202 to 217) (a) For Q64AD-DGH The reference values change depending on the setting of the pass data classification setting (buffer memory address 200: Un\G200).
7 ONLINE MODULE CHANGE MELSEC-Q 7.5 Precautions for Online Module Change The following are the precautions for online module change. 7 - 36 (1) Always perform an online module change in the correct procedure. A failure to do so can cause a malfunction or failure. (2) If an online module change is made with the user range setting, the accuracy after that will fall to about less than three times of the accuracy before that. Re-set the offset/gain values as necessary.
