APPENDIX
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: 0DH and 0AH) at the end of the data sent to the PLC CPU side.
Once any end code is registered, data can be transmitted in the same way as for the
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 PLC 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
2)Create a new program for data communication upon checking functions and instructions used on the PLC CPU side in Chapter 7.
Data transmission/reception is performed using dedicated instructions.
3)The external device can transmission/receive data in the same way as the
(5)Others
1)The Q series C24 has other functions that are equivalent to those of
2)Check functions and specifications in this manual and the manuals listed below, and use the applicable functions.
