Re: [foxboro] Foxbatch Problem

OMPRAKASH,
Not too sure of your application, but
if you need to run PHASE 1 dependent on
a the value of a tag (II0001), say II0001 = 4
then build a branch with following information:
Execute - one ; Branch 2
Left most branch with following transition II0001 <> 4
and no operation below it.
Next branch with transition II0001 =4 and Phase 1 operation 
below it.

ensure that Phase 2 is continually computing value II0001 in
whatever mode its in .
Hope this helps

Subject: [foxboro] Foxbatch Problem


Hi
 
We are having a configuration of five CP40A FT, one- AW51C six - WP51B,
two - AB30 and one COM10. AW51C is the host for all the CPs, also
Foxbatch server (Release 3.1) and legacy historian runs on this AW51C.
IA version is 6.1.
 
Presently we are modifying a recipe that involves one phase (say Phase
1) consecutively used two times in the recipe. II0001 of this phase gets
its value for another phase (say Phase 2) which runs in parallel with
Phase 1. There is a transition element which is configured to read the
value of II0001 of Phase 1 located above Phase 1. Based on the Phase 2
logic, this transition element value set from Phase 2. 
 
When we run the recipe, transition element simply execute irrespective
of the value set by phase 2. This causes production problem. We tried to
configure different Phase in place of Phase 1 and also different tag
instead of II0001 transition element. Still same problem.We tried to
change the delta for read & write for IADriver from the default values
of 1 to 0.5 in the file /opt/fox/foxbatch/cmdfile/Run.cmd. No
improvement. Still same problem. 
 
Can any one help me on this.
