FAQ for CP1L-EM40DT1-D
What's the difference between CP1L-EM40DT1-D and CP1L-EM40DT-D?
DT1 is PNP (sourcing) output; DT is NPN (sinking) output. Choose based on your field wiring: PNP for sourcing sensors and NPN-input PLCs (most modern Omron PLCs and most EU installations); NPN for sinking sensors and PNP-input PLCs (older US installations). Mechanically and electrically otherwise identical.
Can CP1L-EM40DT1-D connect to an NS-series HMI over Ethernet?
Yes — the built-in Ethernet port supports both FINS/UDP and FINS/TCP for connection to NS, NB, and NA series HMIs. For NB and NA HMIs, you can also use Modbus/TCP. Set the HMI's PLC type to CP1L-EM in CX-Designer / NB-Designer and configure the Ethernet node on the same subnet as the HMI.
How many expansion units can I add?
Up to 3 CP1W expansion units on the right side, for up to 160 I/O total. Expansion includes digital I/O (8/16/32 point), analog I/O (4/8 channels), temperature inputs (thermocouple or RTD), serial communication ports, and DeviceNet or CompoBus/S master/slave units. Order the CP1W unit to match the specific I/O you need — the catalog lists 50+ expansion options.
Does CP1L-EM40DT1-D support motion control?
Yes — for simple positioning, the 100 kHz pulse outputs (2 axes) drive stepper drivers or as position references to servo drives. For trapezoidal motion profiles, use the PLS2 instruction in the ladder program. For more complex motion (interpolated axes, electronic gearing), step up to a CP1H or NX102 with native motion controllers.
