When installing the PROFIBUS Master Unit on the PLC system, observe the
following handling precautions
• Always turn OFF the power supply to the PLC before mounting or dis-
mounting a Unit or connecting or disconnecting cables.
• Provide separate conduits or ducts for the I/O lines to prevent noise from
high-tension lines or power lines.
• Leave the label on top of the Unit attached when wiring. Removing the
label prior to wiring may result in malfunction if foreign matter enters the
Unit.
• Remove the label after the completion of wiring to ensure proper heat dis-
sipation. Leaving the label attached may result in malfunction.
The CS1W-PRM21 PROFIBUS Master Unit can be mounted to any slot in
either a CS-series CPU Rack, a CS-series Expansion CPU Rack or a CS1
Duplex CPU Rack. The CS-series PLC supports up to 7 Expansion CPU
Racks, in addition to the CPU rack.
The number of slots to which PROFIBUS Master Unit can be mounted
depends on the Backplane. Up to 16 PROFIBUS Master Units can be
mounted to a single PLC system. If it is mounted in combination with other
CPU Bus Units (e.g., Ethernet Units), the maximum total number of CPU Bus
Units that can be mounted is 16.
.
3, 5, 8, or 10 slots
Note The CS1W-PRM21 PROFIBUS Master Unit's maximum current consumption
is 400 mA. Make sure that the total current consumption of all the Units con-
nected to the same CPU Backplane or Expansion Backplane does not exceed
the output capacity of the Power Supply Unit.
CS-series CPU Rack
Can mount to any position,
with 2, 3, 5, 8, or 10 slots.
CS-series Expansion Rack
Can mount to any position,
with 3, 5, 8, or 10 slots.
C200H Expansion Rack
PROFIBUS DP Master Unit cannot be
mounted to any slots.
