Introduction
Content
- CP1L/CP1H as a Programmable I/O Module
- Programming and FINS
The CP1W-EIP61 supports programming and FINS messaging.
- PLC Support
The adapter mounts in an Option Board Slot on the front of a CP1L/H PLC, and can be used in all CP1L/H PLCs with an available Option Board Slot. The CP1W-EIP61 is not supported by the CP1E PLC.
- Normal Mode
The CP1W-EIP61 adapter allows other PLCs to connect to an Omron CP1L/H PLC and share up to 100 words of data in each direction with the originator PLC. Assemblies are provided to produce and consume 20 bytes (10 words), 40 bytes (20 words) 100 bytes (50 words) or 200 bytes (100 words) of PLC data.
- I/O Block Mode
Special assemblies (Input_120 and Output_121) have been provided to allow the originator PLC to directly read the inputs and directly control the outputs of the CP1L/H. The maximum I/O configuration of a CP1L/H can be used, and the I/O is mapped directly over EtherNet/IP without the need of programming or additional configuration of the CP1L/H PLC. In this case, the CP1L/H PLC functions as an I/O block.
Additional Notes
The provided assemblies map specific I/O areas for produced and consumed words in the Originator and CP1 PLCs. See the table below for details.
ASSEMBLY I/O MAPPING
NOTE: Using the software Network Configurator for EtherNetIP, the Name Field of the Edit Tags dialog box represents the Originator PLC's (e.g. CJ2M-CPU33) I/O memory address or network symbol for produced and consumed locations (e.g., 100, W100, D0, Input_Signal). Additionally, The H, W, D, and E characters can also be input in lower case as h, w, d, and e. Directly enter the CPU Unit's I/O memory address (e.g., 100, W100 , D0) or a network symbol as a character string. Addresses in the following I/O memory areas can be set.
| CPU Unit's Data Area | CPU Unit's Data Area Address |
| CIO Area | 0000-6143 |
| HR Area | H000 to H511 |
| WR Area | W000 to W511 |
| DM Area | D00000 to D32767 |
| EM Area | E0_00000 to E18_32767 (available EM Banks depend on CPU type) |
Examples for allocated memory areas are shown below for various assembly types using the Watch Window from CX-Programmer to illustrate the data exchange over EtherNet/IP.

Mode Selection
The mode (Normal Mode or I/O Block Mode) of the CP1W-EIP61 unit is configured by selecting the appropriate assembly shown above. The originator configuration determines the operating mode of the CP1W-EIP61.
Compatible PLCs
CP1L-L, CP1L-EL, CP1L-EM, CP1L-M, CP1H-Y, CP1H-X
*NOTE: Compatible only when an option port is available.
