APPENDICESINDEX
(1) Function
Switches the mode of the Q68TD-G-H02(H01) converter module
• Normal mode to offset/gain setting mode (the offset/gain setting mode status flag
(XA) turns ON)
• Offset/gain setting mode to normal mode (the offset/gain setting mode status flag
(XA) turns OFF)
POINT
(1) When the offset/gain setting mode is switched to the normal mode, Module
ready (X0) turns from OFF to ON.
Note that initial setting processing will be executed if there is a sequence
program that makes initial setting when Module ready (X0) turns ON.
(2) When the normal mode is switched to the offset/gain setting mode, all
channels set to temperature conversion disable.
Set the channels where offset/gain setting will be made for conversion enable
and turn ON the operating condition setting request (Y9).
(3) When the offset/gain setting mode is switched to the normal mode, restore
the normal mode status prior to switching to the offset/gain setting mode and
start temperature conversion.
(2) Operation error
No errors.
(3) Program example
The following program is designed to switch the Q68TD-G-H02(H01) converter
module mounted in the position of I/O number X/Y0 to X/YF to the offset/gain setting
mode when M10 is turned ON, and to return it to the normal mode when M10 is turned
OFF.
