• Make sure that the required data, including the user program, configurations, settings, variables, and
memory used for CJ-series Units, is transferred to a CPU Unit that was replaced and to externally
connected devices before restarting operation.
Be sure to include the routing tables, network parameters, and other CPU Bus Unit data, which are
stored in the CPU Unit.
Disposal
• Dispose of the product and Batteries according to local ordinances as they apply.
• The following information must be displayed for all products that contain primary lithium batteries with
a perchlorate content of 6 ppb or higher when shipped to or transported through the State of Califor-
nia, USA.
Perchlorate Material - special handling may apply.
See www.dtsc.ca.gov/hazardouswaste/perchlorate.
• The CPU Unit contains a primary lithium battery with a perchlorate content of 6 ppb or higher. Place
the above information on the individual boxes and shipping boxes when shipping finished products
that contain a CPU Unit to the State of California, USA.
Using CompoNet Units
• Always set the same communications mode number on the rotary switch on the front of the Compo-
Net Master Unit and for the communications mode number setting when you register the Unit on the
Sysmac Studio (MODE@ in the Unit Name). If the numbers are not the same, the CompoNet Master
Unit will operate with the communications mode number that is set on the rotary switch on the front
panel, but the I/O ports that are assigned for slave I/O data will be created according to the communi-
cations mode number that is registered on the Sysmac Studio. If this happens, data will be accessed
for a different Slave Unit or a different item when you try to access I/O data for the Slave Unit. Set the
communications mode number carefully.
• When Flat Cable I (unsheathed) or Flat Cable II (sheathed) cables are used for more than one Com-
poNet system, do not bundle the cables from two different CompoNet systems together. Always sep-
arate the cables from each other by at least 5 mm to prevent unstable operation of the systems due to
interference.
• Always configure the control circuits so that they turn ON power to the I/O Slave Units before they
turn ON power to the Controller with the Master Unit. If the power to the Controller is turned ON first,
normal operation will temporarily not be possible.
• Use only the specified communications cables.
• Do not extend the connection distances of the communications cables beyond the ranges given in the
specifications.
