Serial Communications Units (CS/CJ Series)
Note
1.
Set the Serial Communications Unit mode and the communications set-
tings (System Setup) in the words allocated in the DM Area. Use a Pro-
gramming Device, such as a Programming Console or the CX-
Programmer, to make these settings. The System Setup is transferred to
the Serial Communications Unit at the following times:
• When the power to the CPU Unit is turned ON, when the Serial Com-
munications Unit is restarted (a bit between A50100 to A50115 is
turned ON), or when the STUP(237) instruction is executed.
