Appendix C
When Using CS1-series PCs
Overview
With CS1-series PCs, Slaves are connected to the PC using a C200H-RM201 SYSMAC BUS Wired Remote
I/O Master Unit (2-wire). Words in the SYSMAC BUS Area or the I/O Terminal Area are allocated for inputs
and outputs.
Differences in Memory Areas
When using CS1-series PCs, the following areas are affected by differences in memory allocation. (Details
given in Data Configuration below.)

Data Configuration
SYSMAC BUS Area (Slave Rack Allocation)
CIO 3000 to CIO 3049 are allocated to C200H Remote I/O Slave Units based on their unit number settings (0
to 4) in 10-word blocks. From each 10-word block, 16 bits are allocated to each slot (even if the slot is not
used) of the Slave Rack starting from the left (the slot farthest from the Slave Unit).
Note 1. The words are allocated according to unit numbers even when two Master Units are being used.
2. If C500 Remote I/O Slave Racks (C500-RT201) are used, the word allocation for each Slave Rack
will be twice (i.e., 20 words) that of C200H Slaves. Unit numbers #0 to #3 can be set (although con-
secutive unit numbers cannot be set.)
Unit number of Slave Unit CS1 C200H/HX/HG/HE/HS
0 CIO 3000 to CIO 3009 IR 050 to IR 059
1 CIO 3010 to CIO 3019 IR 060 to IR 069
2 CIO 3020 to CIO 3029 IR 070 to IR 079
3 CIO 3030 to CIO 3039 IR 080 to IR 089
4 CIO 3040 to CIO 3049 IR 090 to IR 099
I/O Terminal Area (Allocation for Slaves Other than Slave Racks)
Each Slave is allocated 1 word based on its unit number setting (0 to 31) except for Optical I/O Units, which
are allocated 2 words each.
Note The words are allocated according to unit numbers even when two Master Units are being used.

Note When using two Masters, ensure that the word allocations do not overlap.
