7. AUTO REFRESH FUNCTION
*1 "n" is determined by the installation location of the master modules.
*2 When the total number of remote I/O station is odd, add 1 to the station number to obtain the
occupied storage devices.
*3 When the master module number setting column is made blank in parameter setting, auto
refresh can be used without this setting.
However, model name registration is required in the "I/O Assign". (MINI mode: AJ71PT32,
MINI-S3 mode: AJ71PT32-S3)
*4 When the input (X) is specified in the received data storage device, use the I/O number later
than the number used for the module loaded on the main base unit and the extension base
unit. When the I/O number usage range for the module loaded on the main base and the
extension base is used for input/output of the received data storage device, the CPU module
imports both the input ON/OFF data from the input module and the ON/OFF data from auto
refresh of MELSECNET/MINI-S3. Therefore, input (X) of the CPU module is not operated as
desired.
