C200H DeviceNet Area

1,2,3...
The C200H DeviceNet Area is divided into two parts:
1. The DeviceNet Output Area contains 50 words with addresses ranging
from CIO 0050 to CIO 0099.
2. The DeviceNet Input Area contains 50 words with addresses ranging from
CIO 0350 to CIO 0399.
Words in the C200H DeviceNet Area are used for fixed allocations to Slaves
for DeviceNet remote I/O communications for the C200H DeviceNet Master
Unit (C200HW-DRM21-V1).
Note The CS-series DeviceNet Unit (CS1W-DRM21) does not use this
same area for fixed allocations, but rather uses the CS-series De-
viceNet Area (CIO 3200 to CIO 3799).
Data is exchanged regularly to Slaves in the network (independent of the pro-
gram) through the C200H DeviceNet Master Unit (C200HW-DRM21-V1)
mounted in the CPU Rack.
Words can be allocated to Slaves in two ways: fixed allocation (words allo-
cated by node number) or free allocation (user-set word allocation).
• With fixed allocations, words in the C200H DeviceNet Area are allocated
automatically in node-number order.
• With user-set allocations, the user can allocate words to Slaves from the
following words.
CIO 0000 to CIO 0235, CIO 0300 to CIO 0511, CIO 1000 to CIO 1063
H000 to H099
D00000 to D05999
The same ranges can be allocated for both CS-series and C200HX/G/E PLCs
except that LR 00 to LR 63 in the C200HX/G/E PLCs correspond to CIO 1000
to CIO 1063 in the CS-series PLCs. (The entire Master Status Area is from
D06032 to D06063.)
For details on word allocations, refer to the C200HDeviceNet Operation Man-
ual (W267).

With fixed allocation, words are assigned according to node numbers.
(If a Slave requires two or more words, it will occupy as many node
numbers as words required.)
