[PARAMETER ERROR]
• The PLC parameter setting for "Points occupied by
empty slot" is outside the range for the remote I/O
module.
• The parameter setting in the individual information of
the error (the special register SD16) is invalid.
Collateral information
• Common Information (SD5 to SD15): File name
• Individual Information (SD16 to SD26): Parameter
number
Diagnostic Timing
• At power-on/At reset
*2
• Read the individual information of the error
using GX Works2 or GX Developer to
identify the numeric value (parameter
number). Check the parameters
corresponding to the value, and correct
them as necessary.
• Rewrite corrected parameters to the remote
I/O module, reload the power supply of the
remote I/O module and/or reset the module.
• If the same error occurs, the cause is a
hardware failure. (Please consult your local
Mitsubishi representative.)
