Hardware Specifications

Omron PLC Backplane Bus & Signal Processing

The CP1E-N60S1DR-A renewal application CPU interfaces integrated I/O blocks using an internal high-velocity logic bus, eliminating scanning latencies across its 36 DC input and 24 relay output circuits. The built-in RS-485 port operates directly through the CPU core, executing Modbus-RTU easy master commands and Serial PLC Link communications without requiring external serial option boards. Program execution occurs via non-volatile flash memory updates, maintaining cyclic scan times while servicing high-speed counter interrupts and RS-485 serial packet queues.

Field Installation Guidelines

• DIN Rail Mounting: Latch the controller onto a standard 35 mm DIN rail (TH35-7.5/TH35-15). Retain at least 50 mm clearance above and below the housing to maintain convection airflow.
• AC Supply Wiring: Connect 100 to 240 VAC power conductors (AWG 14 to AWG 18) to terminals L1 and L2/N. Torque terminal block screws to 0.5 N m.
• RS-485 Shielding & Termination: Wire 2-wire RS-485 networks using twisted pair shielded cabling. Connect a 120 Ohm (1/2 W) terminating resistor across terminals A and B at both ends of the physical bus line.
• Earthing Procedure: Connect the functional ground (FG) terminal to an earth ground electrode with a resistance below 100 Ohm using a minimum 2.0 mm2 conductor.

Frequently Asked Questions

• Does the built-in RS-485 interface support 4-wire full-duplex communication?

  No. The built-in RS-485 port on the S1 renewal model is hardwired for 2-wire half-duplex communication protocols such as Modbus-RTU and Serial PLC Link.

• Is hot-swapping permitted for connected expansion units or terminal blocks?

  No. Main supply power must be fully disconnected before modifying screw terminal connections or adding local CP1W expansion modules to avoid backplane damage.

• What digital input filtering time constants can be configured in CX-Programmer?

  The hardware input filter delay is software-configurable from 0 ms (no filter) up to 32 ms to eliminate contact bounce from external field switches.

• What memory area retains program register states during long-term power outages?

  User ladder logic programs and parameter settings store directly to non-volatile flash memory, while DM registers and counter values are preserved via battery backup.

• What maximum wire size is supported by the built-in I/O terminal screws?

  The integrated M3 terminal screws accept solid or stranded copper conductors ranging from 0.08 mm2 to 2.0 mm2 (AWG 28 to AWG 14) fitted with crimp ferrules.

• What is the response frequency for high-speed counter inputs on this CPU?

  High-speed counter inputs process single-phase pulse inputs up to 100 kHz, or differential phase-difference pulse inputs up to 50 kHz across 6 dedicated axes.

• Can the relay outputs directly drive inductive loads without external suppression?

  Relay contacts switch up to 2 A at 250 VAC / 24 VDC resistive, but inductive loads require external RC surge absorbers (AC) or freewheeling diodes (DC).

• What derating factor applies when operating near the 55 deg C upper thermal limit?

  At an ambient operating temperature of 55 deg C, the simultaneous ON ratio of all combined digital input and relay output points must not exceed 80 percent max.
