• DTXDU(262) will not be executed while the DTXDU(262) Send Ready Flag (n+9/n+19 bit 04) is OFF
(n = CIO 1500 + 25 × unit number). Use the DTXDU(262) Send Ready Flag in an NO input condition
for DTXDU(262).
Example Programming
In the following sample, if CIO 0.00 is turned ON while the DTXDU(262) Send Ready Flag (CIO
1559.04) is ON, 5 bytes of data starting from the lower byte of D100 will be sent to the external device
connected to port 1 of the Serial Communications Unit with unit number 2 without converting the data in
any way.
