What is the format to address a bit in an Omron CJ1M PLC directly, without creating a bit tag? The object visibility option only allows for words, but I would like to display objects depending on the bit status. Am I missing something?

If you have a word in redlion, use the period to display or use the appropriate bit

ie word.4

This does not work. Please view the jpg. to see what I mean. Thanks

mjoubert,

A flag tag will reference the bit in your PLC and then you can enter the flag tag in the Show Item box.

Thanks
Jeremy

I assume then that this is not possible?

Could this be added as a feature to the visibility combo box in both C2 and C3?

The driver performs all transactions with the Omron PLC using words, so no, you can't directly create a bit reference to the PLC. Not sure if this is a protocol issue or just how we did it -- it's an old driver -- but either way, you need to use a bit tag. If you don't want to create the tag, you can also use something like [PLC1.IM0004].0 to select bit 0 from IM4.

Thanks Mike,

This option seems to do the trick.
