BITS N BYTES

For your application and small amount of data you could use Serial PLC Link to exchange data via the serial ports of each PLC. Very simple, reliable and easy to setup. Requires NO PROGRAMMING in the PLC. It is setup/configured in the PLC settings.

Final notes. IF you have the correct model CP1E-N type PLC have you selected the correct DEVICE TYPE and CPU TYPE in CX_Programmer?

I hope your CP1E PLC model suffix is type CP1E-N. Only this model type will allow high speed pulse outputs. To configure the outputs you also use the PLC settings to configure either or both Pulse Output 1 and Pulse Output 2.   Again don't forget to download these new setting to the PLC and POWER CYCLE to accept new settings.  

In order to use I/O for high speed tasks/instruction they must be configured in the PLC settings and downloaded to the PLC. After downloading you MUST power cycle the PLC for these new setting to work.  

The DMPX instruction control word C specifies how conversion occurs. Setting third digit of the C word to 0 specifies 16-to-4bits conversion. Between 1 and 4 words can be processed based the setting of digit 1 by setting it between 0-3. Setting digit of the C word to 1 specifies 256-to-8 bits conversion. In this case a block of contiguous block of 16 or 32 words is searched by setting digit to 0 or 1.   For a full explanation and sample code for this instruction in Omron Manual W340. Here is link:- http://www.edata.omron.com.au/eData/PLCs/CJ1/W340-E1-17.pdf    

Data Encoder:- DMPX(077) Instruction might be what you are looking for?

Good luck. Let us know if this works out for you! Regards

You could try using the BACKUP/RESTORE procedure using a CF card. BACKUP exiting PLC program to CF Card. RESTORE program to other PLC using CF Card. Depending on how the program was originally protected this should work. BUT if the other PLC is a different Version # this may cause a problem. CJ1 CF card backup & restore guide.pdf

Well how about sharing with this forum what the fault was and how you resolved it?

Does this suit your requirements? https://www.automationdirect.com/adc/overview/catalog/programmable_controllers/productivity_open_(arduino-compatible)

Note that for the CP2E function block cannot use STRING data types.  

There ARE some restrictions on the CP2E series PLC's relating to Function Blocks and Structured Text. See manual W614. Attached is extract from manual for ST. This MAY be causing your issue. W614-E1-01.pdf   Apologies, original attachment was not working W614-E1-01-Extract.pdf
