The production inhibit time value was set
to 0ms (set value 1) in cyclic. • Set the production inhibit time value to a
value other than 0ms.

DNTMRD was not executed for three
sequence scans although "Data
consistency dedicated instruction setting
for master function" is enabled.
• Correct the sequence program so that
DNTMRD is executed in every scan.
• When not using Data consistency
dedicated instruction, disable "Data
consistency dedicated instruction setting
for master function", then turn on I/O
Communication Request (Y11).
