CPUs
The four models of CPUs can be broadly divided into two groups: Models that support Inner Boards and the Controller Link Unit, and
models that do not. The CPUs also vary in their program capacities, I/O capacities, memory capacities, and the presence of an RS-232C
port, as shown in the Basic Specifications table, below.
J NOMENCLATURE
The following illustration shows the main components of a CQM1H-CPU61 CPU.
J OVERVIEW
J MAXIMUM NUMBER OF MODULES
Note: I/O capacity = Number of input points (≤ 256) + Number of output points (≤ 256).
Battery Compartment Cover
Open this cover to access the battery,
DIP switch, and Memory Cassette.
Mini-Peripheral Port
Used to connect to Programming De-
vices such as a Programming Console or
a computer running CX-Programmer.
Also supports Host Link and no-protocol
communications.
RS-232C Port (except CQM1H-CPU11)
Used for Host Link, no-protocol, 1:1 Data
Link, or NT link (1:1 mode) communications
with external devices or other PLCs.
