Note 1 In a CompoNet Network, Word Slave Units have 16 bits per node address.
2 Do not set the reserved communications mode numbers (4 to 7 and 9). A communications
mode setting error (H4 at the 7-segment LED indicator) will occur if any of these modes is
set.
Also, when the CompoNet Master Unit is registered in the Unit Configuration on the Sysmac Studio,
one of the following unit names is selected and registered according to the communications mode.
CJ1W-CRM21 (MODE0), CJ1W-CRM21 (MODE1), CJ1W-CRM21 (MODE2), CJ1W-CRM21
(MODE3), or CJ1W-CRM21 (MODE8)
The device variables for the CJ-series Unit are created according to the communications mode number
of the unit name. The same communications number must be set on the rotary switch on the front panel
and in the Unit Name of the CompoNet Master Unit when it is registered in the Unit Configuration.
