The Cam Positioner Unit belongs to the C200H Special I/O Unit group. A max-
imum of ten Special I/O Units (including PC Link Units) can be mounted on
the CPU Rack, Expansion I/O Rack, and Slave Rack.
Note 1. Refer to the C200H# PC Operation Manuals or the table below for infor-
mation on which units belong to the Special I/O Unit group.
2. The Units used are limited by the maximum supply current and current
consumption. Refer to the C200H# PC Operation Manuals.
3. The number of Units used with a Slave Rack is limited by data transmission
considerations, as described below.
The number of Special I/O Units used with a Slave Rack is limited by data
transmission considerations, as shown in the table below. The numbers in the
table indicate the maximum number of Units of groups A, B, C, or D which can
be used with a single Slave Rack.

Note 1. When a combination of Units from groups A, B, C, and D is used, the num-
ber from each group must satisfy both the following equations:
3A + B + 2C + 6D ≤ 12
A + B + C + D ≤ 8
2. Other Units can be added until the total number of units reaches ten. If PC
Link Units are used, the number of Units including the PC Link Units must
not exceed ten.
The IR area of the C200H Special I/O Unit is allocated according to the setting
of the unit number switch on the front panel, not the address of the slot where
the unit is mounted. Refer to 4-1 Memory Allocation for the allocation of the
memory area.
Leave the 2 slots next to the CPU free. It is not possible to use devices con-
nected to the CPU (such as the Programming Console) if these slots are
occupied.
If the C200H Slave Rack is connected to another SYSMAC model Remote I/O
Master Unit, such as the C120, C500, C1000H, or C2000H, it is not possible
to use a Special I/O Unit with the C200H Slave Rack.
Always turn the C200H# power OFF before connecting or disconnecting a
Unit, terminal block, or output connector.
Wire I/O leads in separate ducts from power leads to prevent noise problems.
