3 WHEN COMMUNICATING USING THE QnA COMPATIBLE 3E/3C/4C FRAMES OR 4E FRAME
(h) Transmission method in condition agreement transmission
This flag designates which method should be used to transmit the results of
monitoring the programmable controller CPU when condition agreement
transmission is designated in programmable controller CPU monitoring
function (c).
1) Data communication in ASCII code
The value shown below is converted to a 2-digit (hexadecimal) ASCII
code and sequentially transmitted beginning from the most significant
digit ("0").
2) Data communication in binary code
The 1-byte value is transmitted.
3) Designate "00" or 00
in programmable controller CPU monitoring function (c).
4) How the designated values correspond to transmission method of
condition agreement transmission is shown below.

(i) Monitoring conditions
This value (j) designates conditions (for transmitting monitoring results)
when condition agreement transmission is designated in programmable
controller CPU monitoring function (c).
1) Data communication in ASCII code
The value shown below is converted to a 2-digit (hexadecimal) ASCII
code and sequentially transmitted beginning from the most significant
digit ("0").
2) Data communication in binary code
The 1-byte value is transmitted.
3) Designate "00" or 00
in programmable controller CPU monitoring function (c).
4) The following table summarizes the values that can be designated and
the corresponding monitor condition.
