1. These words are used to notify the CPU Unit of the Simple Communica-
tions Unit's status.
2. The functions in parentheses are for CompoWay/F communications.
Range
1: RUN If this digit is set to 1 after the power is turned ON, the Simple Communica-
0: Stop tions Unit will start communications with components and the CPU Unit. (If
a fatal error has occurred, the Unit will not start communications with com-
ponents even if this digit is set to 1.)
The Simple Communications Unit will not communicate with components if
this digit is set to 0.
0 to 9 Sets the response monitoring time for access from the Simple Communica-
(BCD) tions to connected components. The timeout time is set in multiples of
500 ms ((Set value + 1) × 500 ms). This setting is usually set to 0, which
sets a response monitoring time of 500 ms.
00 to 32 Specifies the number of components connected to the Simple Communica-
(BCD) tions Unit. The Simple Communications Unit will not communicate with
components if the number of connected components is set to 0.
