Q Compatible Mode Function - Mitsubishi Electric MELSEC iQ-R Series User Manual

Q Compatible Mode Function

This function controls an operation state with the buffer memory layout of the D/A converter module converted to equivalent of
the addresses of the compatible modules of the MELSEC-Q series.
This compatibility makes it possible to reuse sequence programs that have exhibited high performance on the MELSEC-Q
series analog output modules.
The following table lists the compatible modules of the MELSEC-Q series.

Operation
Only the buffer memory assignment is changed in the Q compatible mode.
• The I/O signal assignment is the same as the one for the R mode. 'High resolution mode status flag' (X8) of the MELSEC-
Q series is deleted and 'Synchronous output mode flag' (XD) is changed to 'Disconnection detection signal' (XD) and
'Synchronous output request' (YD) is changed to 'Disconnection detection clear request' (YD). However, the signals that
change the module operation maintain the compatibility. Therefore, when the MELSEC-Q series program is diverted, a
significant modification is not required.
• When the MELSEC-Q series program is diverted, check digital values and the operation timing and modify
the program if necessary because the specifications such as the resolution and update timing are changed.
• When the MELSEC-Q series program is diverted and an error code is set as the operating condition or
interlock condition, the program does not operate normally.
• When the Q compatible mode function is enabled, a program that uses FB or labels cannot be created.
When FBs or labels are used, create a program in the R mode.
Setting procedure
1.
When adding a new module, select the module whose module name has "(Q)" at the end.
avigation window  [Parameter]  [Module Information]  Right-click  [Add New Module...]
2.
Configure the same parameter setting as the one of when the R mode is used.
3.
Restart the CPU module after the module parameter is written.
• During the module operation, the mode cannot be switched between the R mode and Q compatible mode.
• The project of the compatible D/A converter module created by GX Works2 can be read with the other
format read function of GX Works3. The read project keeps various settings of the compatible D/A converter
module as the settings of the D/A converter module of the MELSEC iQ-R series. The settings to be kept are
the switch setting, parameter setting, auto refresh setting, and I/O assignment.
