z When MD=0 and output control “EN↑” changes from 0→1, it transmits the ASCII data which starting from S
to the communication port 1 (Port1), until reach end of file.
z S file data can be edited with the programming software PROLADDER or WinProladder (please refer to the
explanation of chapter 15 “ASCII function application”.). If necessary the user can also edit the ASCII file
directly by change the value of data registers. However, the edited data must be follow the ASCII file format
(the details described in chapter 15), otherwise, this instruction will halt the transmission and set the error flag
“ERR” to 1. If the entire file is correctly and successfully transmitted, then the output is completed and “DN”
is set to 1.
z The control input of this instruction is of positive edge triggered. Once “EN↑” changes from 0→1 then this
instruction starts the execution, until finished the transmission of the entire file then the execution is completed.
During the transmission, the action flag “ACT” will be kept at 1 all the time. Only when output pause, error, or
abort occurs, will it change back to 0.
z This instruction can be repeatedly used, but only one will be executed (transmit data) at any certain time. It is
the obligation of user to make sure the right execution sequence.
z While this instruction is in execution, if the pause “PAU” is 1, this instruction will pause the transmission of file
data. It will resume transmission when the pause “PAU” backs to 0.
z While this instruction is in execution, if the abort “ABT” is 1, this instruction will abandon the transmission of
file data, and then it is able to take next instruction for execution.
z or detail applications, please refer to chapter 14 “The Application of ASCII file output function”.
