Hardware Specifications

Omron PLC Backplane Bus Velocity & Signal Processing

The CP1L-M60DR-D CPU unit executes high-density ladder logic utilizing a cyclic scanning control method with immediate refreshing. The internal CPU backplane bus coordinates real-time data exchange across the 36 DC input and 24 relay output channels without scan cycle jitter. Fast-response interrupt routines handle dedicated inputs down to 0.3 ms delay, while the 4-axis 100 kHz high-speed counter channels interface directly with board-level hardware registers. When expanding the physical system, the local expansion bus maintains deterministic timing across up to 3 connected CP-series I/O modules.

Package Contents & Ordering Information

• 1x Terminal block protective cover assembly
• 1x Lithium battery unit (pre-installed or packaged)
• 1x Hardware installation sheet

Field Installation Guidelines

• DIN Rail Mounting: Mount the unit on a standard 35 mm DIN rail (TH35-7.5 or TH35-15). Ensure a minimum clearance space of 50 mm above and below the housing for natural convection cooling.
• DC Power Wiring: Wire 24 VDC supply power to the designated power terminals using AWG 14 to AWG 18 conductors. Tighten terminal screws to a torque spec of 0.5 N m.
• Grounding & Shielding: Terminate the functional ground (FG) lead directly to a dedicated earth electrode with a resistance below 100 Ohm. Keep signal lines and DC power cabling separated from high-voltage AC wiring by at least 100 mm.
• Expansion Bus Assembly: Prior to connecting CP-series expansion units, isolate system power and remove the right-side expansion bus cover from the CPU main unit.

Frequently Asked Questions

• Is hot-swapping allowed for terminal connections or expansion units on the CP1L-M60DR-D?

  No. System power must be fully isolated before wiring, removing terminal connections, or connecting CP-series expansion modules to avoid backplane bus damage.

• What data memory areas are retained by the internal backup battery?

  The backup battery retains the Holding Area (H0 to H511), DM Area (D0 to D32767), and counter values/flags during main power interruptions.

• What is the expected battery service life under standard ambient conditions?

  The service life expectancy of the backup battery is 5 years at an ambient temperature of 25 deg C, derating at higher continuous operating temperatures.

• Does the relay output version support transistor-level high-speed pulse outputs?

  No. Pulse output functions at 100 kHz are restricted to transistor output models; the CP1L-M60DR-D provides electromechanical relay outputs only.

• How many total tasks can be structured within the CPU firmware programming execution?

  The CPU logic architecture supports up to 288 total tasks, comprising 32 cyclic tasks and 256 interrupt tasks.

• What maximum wire gauge fits the CPU terminal block assemblies?

  The screw terminals accommodate solid or stranded copper wires ranging from 0.08 mm2 to 2.0 mm2 (AWG 28 to AWG 14) with insulated crimp terminals.

• What is the input response time for the 6 dedicated hardware interrupt inputs?

  The interrupt input channels feature a response execution delay of 0.3 ms, or operate in counter mode up to a maximum frequency of 5 kHz.

• What thermal derating occurs when operating at the upper temperature threshold of 55 deg C?

  At an ambient temperature of 55 deg C, the simultaneous ON ratio for all combined input and output points must not exceed 80 percent of full hardware capacity.
