Interval Timer CPM1 PCs have a high-speed interval timer which can be set from 0.5 ms to
319968 ms. The timer can be set to trigger a single interrupt (one-shot mode) or
repeat scheduled interrupts (scheduled interrupt mode).
High-speed Counter CPM1 PCs have a high-speed counter that can be used in incremental mode or
up/down mode. The high-speed counter can be combined with input interrupts
to perform target value control or zone comparison control that isn’t affected by
the PC’s cycle time.
Analog Setting Function The CPM1 PCs have 2 analog volume controls that can be used to make manual
analog settings.
Host Link Communications The CPM1 PCs are compatible with the Host Link, which allows communica-
tions with personal computers. The CPM1 using the Host Link can also commu-
nicate with Programmable Terminal using host link commands.
An RS-232C Adapter is used for 1-to-1 communications and an RS-422 Adapter
is used for 1-to-n communications.
1-to-1 Link A data link can be created with a data area in another CPM1, CQM1, or C200HS
PC. An RS-232C Adapter is used to make the 1-to-1 connection.
NT Link Communications High-speed operations can be achieved by providing a direct access by con-
necting the CPM1 to the Programmable Terminal through the NT Link Interface.
An RS-232 Adapter is used for this connection.
Standard Peripheral Devices The CPM1 uses the same Programming Consoles, SYSMAC Support Software
(SSS), and Ladder Support Software (LSS) as the Mini H-type and CQM1 PCs.
Programming operation is possible through the PT screen by using an OMRON
PT that has a built-in Programming Console function.
1-1-2 I/O Terminal – IR Bit Allocation
The following table shows which IR bits are allocated to the I/O terminals on the
CPM1’s CPU Unit and Expansion I/O Unit.
Note Refer to Section 6 Analog I/O Unit for details on I/O allocation for the Analog I/O
Unit.
