Timer datatype in cx programmer

[professor_jonny]

what is the timer datatype used for in cx programmer as it just causes compile error when you try to use it on a timer or timer output bit.

 

I have just allways wondered but never have figured it out.

I believe the TIMER Data Type is only allowed in the CJ2 Series PLCs.

I have allways just used the bool datatype as i could not get the timer one to work.

Yep - use the BOOL - it works.

In the end it makes no difference. The PLC will process it just the same. I remember when Omron introduced Data Types. I believe it created more confusion for many new programmers at the time. They are merely a convenience for the programmer to understand what he/she is dealing with, and to give compile warnings. I've programmed many CJ2s and didn't even know the TIMER Data Type existed until a few years ago.

The IEC platform (NJ) is a different story.

As I recall there were a few versions of CX-P that would default to the Timer data type on PLC's that did not support it resulting in a compile error. Rather irritating!!
