(3) Personal computer link communication error flag (M2034)
....………. Status signal
This flag turns on when the communication error occurs in the personal
computer link communication.
• ON : Personal computer link communication error occurs
• OFF: No personal computer link communication error
(It turns off if normal communication is resumed.)
Refer to APPENDIX 2.5 for details on the PC link communication errors.
(4) System setting error flag (M2041)................................. Status signal
This flag set the "system setting data" and performs an adjustment check with a
real installation state (CPU base unit/extension base units) at the power supply
on or resetting of the Motion CPU.
• ON .......... Error
• OFF .......... Normal
(a) When an error occurs, the ERR. LED at the front of the CPU turns on.
The error contents can be confirmed using the error list monitor of a
peripheral device started by SW6RN-GSV43P.
(b) When M2041 is on, positioning cannot be started. Remove an error factor,
and turn the power supply on again or reset the Multiple CPU system.
REMARK
Even if the module which is not set as the system setting with the peripheral device
is installed in the slot, it is not set as the object of an adjustment check. And, the
module which is not set as the system setting cannot be used in the Motion CPU.
