Explicit Message Communications
Any PC data area can be accessed from the Master.
Read/Write: 2,048 words (DM 0000 to DM 2047)*
Read-only: 456 words (DM 6144 to DM 6599)
PC Setup: 56 words (DM 6600 to DM 6655)
*The Error Log is contained in DM 2000 to DM 2021.
2 interrupts
Shared by the external interrupt inputs (counter mode) and the quick-response inputs.
1 (Scheduled Interrupt Mode or Single Interrupt Mode)
One high-speed counter: 20 kHz single-phase or 5 kHz two-phase (linear count method)
Counter interrupt: 1 (set value comparison or set-value range comparison)
2 inputs
Shared by the external interrupt inputs and the quick-response inputs.
2 points with no acceleration/deceleration, 10 Hz to 10 kHz each, and no direction control.
One point with trapezoid acceleration/deceleration, 10 Hz to 10 kHz, and direction control.
Two points with variable duty-ratio outputs.
(Pulse outputs can be used with transistor outputs only, they cannot be used with relay
outputs.)
1 point:
A pulse output can be created by combining the high-speed counter with pulse outputs and
multiplying the frequency of the input pulses from the high-speed counter by a fixed factor.
(This output is possible with transistor outputs only, it cannot be used with relay outputs.)
2 inputs
Shared by the external interrupt inputs and the interrupt inputs (counter mode).
Min. input pulse width: 50 µs max.
Can be set for all input points.
(1 ms, 2 ms, 3 ms, 5 ms, 10 ms, 20 ms, 40 ms, or 80 ms)
Shows the year, month, day of the week, day, hour, minute, and second. (Battery backup)
(CPM2C-CIF01 or CPM2C-CIF11) is required to connect to the CPM2C-S' communications
port. The communications port can be used as both a peripheral and RS-232C port.
Peripheral port:
Supports Host Link, peripheral bus, no-protocol, or Programming Console connections.
RS-232C port:
Supports Host Link, no-protocol, 1:1 Slave Unit Link, 1:1 Master Unit Link, or 1:1 NT Link
connections.
HR area, AR area, program contents, read/write DM area contents, and counter values
maintained during power interruptions.
