Hardware Specifications

Omron Backplane Bus Velocity & Real-Time Logic Execution

The CP1L-M40DR-D features an optimized memory structure that processes basic instruction execution cycles in 0.55 us min. Internal cyclic scanning operates with immediate input/output refreshing across 1,600 CIO bits (100 input words / 100 output words). The system CPU expansion backplane supports local attachment of up to 3 CP-series expansion or expansion I/O units, scaling overall hardware execution capacity to 160 total I/O points. Firmware flash non-volatile memory secures user programs, function block definitions (up to 128 definitions and 256 instances), and system parameters during power removal.

Field Installation Guidelines

• Subrack Mounting: Secure the CP1L-M40DR-D onto a standard 35 mm DIN rail or surface-mount directly inside the control enclosure using M4 screws, maintaining a minimum 50 mm clearance above and below for thermal convection.
• DC Power Supply Wiring: Connect the main 24 VDC operating supply to the designated DC terminal block using AWG 18 to AWG 14 insulated copper wire.
• Relay Output Protection: Install inductive load suppression devices (RC networks across AC field loads or flyback diodes across DC field loads) directly at switched field devices to suppress switching transients.
• Grounding Protocol: Connect the Functional Earth (FE) terminal to the central copper panel ground bar using a short, heavy-gauge copper conductor with measured ground resistance under 100 Ohms.

Frequently Asked Questions

• Is hot-swapping permitted for expansion modules attached to the CP1L-M40DR-D?

  No. Main system power must be completely turned off before installing or removing local CP-series expansion units to avoid backplane bus damage.

• What operating input voltage range is required for the CP1L-M40DR-D?

  The controller requires a nominal 24 VDC power supply with an acceptable operational range between 20.4 VDC and 26.4 VDC.

• What high-speed counting capabilities are integrated into this CPU model?

  The hardware includes 4-axis high-speed counter inputs supporting response frequencies up to 100 kHz for differential or single-phase pulse train acquisition.

• How many total I/O points can be controlled using local expansion units?

  The CPU provides 40 built-in I/O points and supports up to 3 expansion units (40 points each), scaling total system density to 160 I/O points.

• What memory structure is allocated for holding relay data during power cycles?

  The holding area consists of 8,192 bits (512 words from H0.00 to H511.15) reserved for non-volatile parameter retainment.

• What minimum pulse width is recognized on the quick-response input terminals?

  The quick-response input channels accept high-speed field pulses with a minimum pulse width requirement of 50 us or less.

• What cable shielding standard must be applied to serial and high-speed input signals?

  Signal and serial wiring must utilize overall twisted-pair shielded cables with 360-deg braid shield clamping connected directly to panel earth.

• What environment conditions are required for non-operating storage of spare modules?

  Uninstalled spare CPUs must remain stored inside anti-static bags in ambient conditions between -20 and +75 deg C in non-condensing relative humidity.
