(2) Data transmission to the external device while performing communication
using the non procedure protocol
(a) The device information and CPU information are sent by the word/byte unit
designations.
When the communication data ASCII-BIN conversion is designated, it is converted to ASCII code data and
sent. (Examples are shown in Page 48, Section 2.2.5 (2) (f)).
• When the word/byte unit designation is word
The device information and CPU information are each sent in one-word segments in a (H) (L) sequence.
• When the word/byte unit designation is byte
The device information and CPU information are each sent in one-word segments in a (L) (H) sequence.
When the interface that is to use the modem function is set in the non procedure protocol, connection
processing and disconnection processing to the modem are performed when the programmable controller CPU
monitoring results are transmitted.
Data transmission by non procedure protocol with modem function (condition agreement transmission)
(b) When sending monitoring results as data during constant cycle transmission, the
device information of two or more user frame No. and programmable controller CPU
status information that have been currently designated for the constant cycle
transmission by the Q series C24.
(c) When sending the monitoring results as data during condition agreement
transmission, the device information of two or more user frame No. and
programmable controller CPU status information that have been currently
designated by the Q series C24 for the condition agreement transmission of the
block where the monitoring conditions match are transmitted in batch mode.
When the monitoring conditions of two or more block match, the device information and programmable
controller CPU status information are transmitted for each block.
When there is an ASCII-BIN conversion of communication data using non procedure protocol, all of the device monitoring
head device number will be converted to hexadecimal ASCII data and sent. (The same conversion is performed during
either constant cycle transmission or condition agreement transmission.)
