APPENDICES
App. - 14
3) When data is received by a reception end code, the external device side
must send the end code data (the default is CR+LF (code: 0D
at the end of the data sent to the programmable controller CPU side.
Once any end code is registered, data can be transmitted in the same
way as for the UC24/C24-S8.
4) The external device side can receive data from the Q series C24 in the
same ways as UC24.
(b) Message transmission by printer function (when using programs designed
for UC24)
1) Message transmission using the printer function of the UC24 can be
implemented by the data transmission function that uses a user frame.
2) For the programmable controller CPU, register and send messages
according to the User's Manual (Application).
Messages handled by the UC24 will become user frames in the Q series
C24.
(4) Data communication using the bidirectional protocol
(a) Setting to add a sum check code to a message
The setting to add a sum check code to a message has been changed. It is
set during switch setting operation by GX Developer.
(b) Data transmission/reception
1) The same data transmission/reception as used by UC24/C24-S8 can be
performed.
2) Create a new program for data communication upon checking functions
and instructions used on the programmable controller CPU side in
Chapter 7.
Data transmission/reception is performed using dedicated instructions.
3) The external device can transmit or receive data in the same way as the
UC24/C24-S8.
(5) Others
1) The Q series C24 has other functions that are equivalent to those of
UC24/C24-S8, which are not mentioned above.
2) Check functions and specifications in this manual and the manuals listed
below, and use the applicable functions.
