I've tried to do my homework on this subject by searching the archives
from this list, but could not find my answer. I've even tried looking
at the Invensys GPS sight, and though the sight is great if I'm too lazy
to pull out my hardcopy versions of B0193AX, I haven't found it to be
any more useful than that. So, I pose the question to the body at
large.
I have created several timer blocks in different compounds and when run
in our lab, they work great. But, when run on our production system,
they double the time, i.e. a timer span of 10 seconds equals 20 actual
seconds. Of course, I considered the possibility that our production
system is located in some kind of time warp and that whenever we were
working in that location we were somehow aging at twice the normal rate.
But I was relieved to find that another timer block created in a
compound that has been on line now for quite some time is working
correctly.
Now that I have put off plans to head down to Walgreen's to buy depends,
and dentucreme, I need to know what is causing the problem. I've been
unable to find any difference in the block or compound defining time
parameters; all the timers are in CP60s, all the station blocks have a
BPC of 0.5s, all compounds have cycle times of 0.5s, and all the timers
have periods of 0.5s. Since the TIM block parameters are few in number
and relatively easy to wrap around I have to assume that there is
something different in the compound or station settings but I have not
been able to find it.
It has to be something simple, but I seem to be stepping over it. Any
ideas?
Thanks
Matt
