Description Action
• Correct the sequence program so that
DNTMWR 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).
• Correct the sequence program so that
DNTSRD is executed in every scan.
• When not using Data consistency
dedicated instruction, disable "Data
consistency dedicated instruction setting
for slave function", then turn on I/O
Communication Request (Y11).
• Correct the sequence program so that
DNTSWR is executed in every scan.
• When not using Data consistency
dedicated instruction, disable "Data
consistency dedicated instruction setting
for slave function", then turn on I/O
Communication Request (Y11).
• Disable "Data consistency dedicated
instruction setting for slave function", then
turn on I/O Communication Request
(Y11).
• Disable "Data consistency dedicated
instruction setting for master function",
then turn on I/O Communication Request
(Y11).
• Set it within the range of 0 to 128 bytes.
• Set it within the range of 0 to 128 bytes.
• Set either of the transmit or receive bytes
to any other than 0.
• Set I/O points of slave nodes in
Parameters for Master Function.
• Set transmit/receive bytes in Parameters
for Slave Function.
(Either of master or slave function values
must be set.)
