I am working in a process industry, in that there are
several sections devided in the SCADA screens and
individual sections may START independently. But sometimes
i am facing problem i.e, if section 2 Stopped by the
operator immediately Section 1 or Section 3 or Section 4 is
getting stopped can you expain the reason behind this?

Answer Posted / sks
this might be due to 2 reasons :
1)scan cycle of the processor has been increased anyhow as
the Dword value is updated after the signal is processed in
module. this extended scan cycle causes difference of
process values on HMI
2) check LAN ports of all stations and also the patch board,
if there is option for redundancy check the healthiness of
redundancy.
