Re: [foxboro] CP60 Failure Error

Kabir,
It looks as if your FT CP60 went single, which is no problem for your 
production area, that's why it's a fault tolerant right? So I don't know 
what you mean by "How could we configure our CP in FAILSAFE mode so that 
it retain the last good value in case pf any such failure". As long as you 
still have the shadow CP taking over as primary there's no problem with 
last good values right?

We've had this kind of errors also, multiple times. Each time the CP was 
replaced. sometimes we had to replace the CP 3 or 4 times in a row, 
sometimes the problem shifted to the other CP in the FT pair. We're fed up 
with these CP60's and the last remaining CP 60 will be replaced by 
ZCP270's in September. 

We changed all the wiring and earthing according to the foxboro standards, 
We even changed from coax to FO, this didn't improve anything to the CP's 
failing. 

Contact your Foxboro rep, maybe you're entitiled to a replacement CP, 
cause the early revision nrs were all changed or recalled. All in all the 
CP60 was never very succesfull, his predecessor the CP40 never caused any 
problems in the 5 years we used them.

[foxboro] CP60 Failure Error






 Dear Experts,

We've experienced a strange CP60 Failure and the details of the system is 
as follow:

CP60 Redundant on I/A system 6.5
with AW51E as Engineernig Station
two WP51D as Operator stations

One of the CP60s got the red indication  and system Alarm observed that 
became Blinking Green after few seconds but the CP60 remained red 
indicated.

the line printer showed the following messages in sequence

15-07-09 16:49:51    0    SYSMON = SYSMN2  03CP02 Process = PMAINT03CP02

Kindly Suggest possibile causes for such failure and How could we 
configure our CP in FAILSAFE mode so that it retain the last good value in 
case pf any such failure.

thanks
