The CJ1W-DRM21 offers selectable baud rates of 500k, 250k, 125k, 93.75k, 46.875k, 31.25k, 20k, and 10 kbps.

Yes, the CJ1W-DRM21 is designed to seamlessly integrate with other CJ1 series modules.

The CJ1W-DRM21 is designed for DIN rail mounting.

Omron PLCs can operate at various voltages, including 24 V DC, 100 V AC, and 200 V AC, depending on the specific model and application requirements.

Omron PLCs primarily use Ladder Logic for programming, which is a graphical representation that mimics electrical relay logic. Other programming languages, such as Structured Text (ST) and Function Block Diagram (FBD), are also supported.

The five standard programming languages in PLCs as defined by IEC 61131-3 are:

  1. Ladder Diagram (LD)
  2. Function Block Diagram (FBD)
  3. Structured Text (ST)
  4. Instruction List (IL) (Note: Instruction List is being phased out in some contexts.)
  5. Sequential Function Chart (SFC)

While many PLC brands are popular, Omron, Siemens, and Allen-Bradley are among the most widely used globally. Omron PLCs, in particular, are favored in various industries for their advanced features and reliability.
