Chapter 3 Operational Description
3 – 5
3.1.5 Remote Frame Operation
The following two methods are available for transmission after remote frame reception.
(1) Automatic response: automatically transmit preset message data in message box
(2) Manual response: set message data and then transmit
3.1.5.1
Automatic Response
After remote frame reception, this method automatically transmits preset message data in message box.
Table 3-1 lists the settings of the message control register.
