Analog I/O Units are classified as C200H, C200HS, and C200HX/HG/HE Spe­cial I/O Units. The maximum totals of Special I/O Units (including PC Link Units)
that can be mounted to a single CPU Unit are shown in the following table.

The Units that belong to the various Special I/O Unit groups are shown in the
following table. Their usage is limited according to the maximum current pro­vided for the Rack and the amount of current consumed by each Unit. For de­tails, refer to the C200H, C200HS, or C200HX/HG/HE Installation Guide.

There are restrictions on the number of Analog I/O Units that can be mounted on
a single CPU Rack, I/O Expansion Rack, or Remote I/O Slave Rack. Ensure that
the number of Units does not exceed the corresponding total given in the follow­ing table and that the total current consumption of the Analog I/O Units and the
Units mounted to the same Rack does not exceed the maximum current pro­vided for the Rack.

There are usage limitations for Remote I/O Slave Racks. Refer to Slave Racks
below for details.

Certain limitations apply to the number of Special I/O Units that can be mounted
on Slave Racks. The following table shows the maximum number of Group A, B,
C, and D Special I/O Units that can be mounted on a single Slave Rack when
only Units of that group are used.

If Units from any of the four groups are to be combined, then both of the following
two equations must be satisfied.

A + B + C + D x 8

When considering the limitations on the numbers of different types of Special I/O
Units that can be used, refer also to Number of Units previously described.

Special I/O Units are allocated IR area addresses according to the unit number
switch settings on their front panels, and not according to the slots in which they
are mounted.

With the C200H, do not mount an Analog I/O Unit in the two slots adjacent to the
CPU Unit. Doing so would prevent peripheral devices such as the Programming
Console from being connected.

Special I/O Units cannot be used on a C200H Remote I/O Slave Rack if the
Slave Rack is connected to different PC (i.e., C500, C1000H, or C2000H).

Precautions Be sure to turn off the power supply to the PC before installing or disconnecting

Units or connecting lines.
To reduce the risk of malfunctioning due to electrical noise, wire input and output

lines in separate ducts from high-voltage and power lines.

1-3SectionSetting the Unit Number

7

When wiring a Unit, place a cover over the top of the Unit to prevent wire clip­pings and so on from getting inside. When the wiring has been completed, the
cover must be removed to prevent heat radiation.

Remove the cover after the
wiring has been completed.

1-3 Setting the Unit Number

The CPU Unit and Analog I/O Units exchange data via the IR area and the DM
area. The IR and DM word numbers that each Analog I/O Unit occupies are set
by the unit number switch on the front panel of the Unit.

Note If the power supply is shared by two channels as shown above, while the con-

nected device 2 outputs 5 V, approximately 1.6 V (one-third of the output volt­age) is generated in input 1.

If a line breakage occurs while using the voltage input, either separate the power
supply from the connected device or use an isolator for each input to avoid the
following problem.

2-3SectionWiring

16

If the line breakage occurs at point A or B as shown in the preceding diagram
while power is shared by the connected devices, a short-circuit line will be
formed as indicated by the dotted line in the above illustration, thus generating a
voltage of approximately one-third to two-thirds of the voltage output from the
connected device. If this kind of voltage is generated while using the Unit at 1 to
5 V, the line breakage may not be detected. If the line breakage occurs at point
C, it will not be detected because the negative (–) side is common.

In case of the current input, this kind of problem will not occur even if the power
supply is shared by the connected devices.

2-3-5 Input Wiring Considerations

When wiring inputs, apply the following points to avoid noise interference and
optimize Analog Input Unit performance.

• Use shielded twisted-pair cable for external connections and power lines.

• Route input cables separately from the AC cable, and do not run the Unit’s

cables near a main circuit cable, high voltage cable, or a non-PC load cable.

• If there is noise interference from power lines (if, for example, the power supply
is shared with electrical welding devices or electrical discharge machines, or if
there is a high-frequency generation source nearby) install a noise filter at the
power supply input area.

2-4 IR and DM Areas

Adjustment Mode

Note 1. Switches A to F can be set for the C200HX/HG-CPU5j-E/6j-E. Setting

numbers A to F for C200H, C200HS, C200HE, or C200HX/HG­CPU3j-E/4j-E PCs will cause an I/O UNIT OVER error and the Unit will
not operate.

2. If two or more Special I/O Units are assigned the same unit number, an I/O
UNIT OVER error will be generated and the PC will not operate.
