In addition to above checks, also check whether the compressor bleed valves are closed and their limit switches are indicating the same.

Any of them will work provided that you have Bailey EWS. Yiu can use NCPM02, if LAN90 PCV is not required.

Back in those days Bailey usedto provide Engineering WorkStation ( Compaq 386 or 80386 based PCs) having following softwares CAD TEXT LADDER DATASHEET TOOLKIT If you have that EWS, you can use TEXT or TOOLKIT to monitor / save / print the configuration.

And its not NCMP01, it is NCPM01. Just for correction.

In first para read Process Control Unit (PCU / Node).

CPM is called Communication Port Module and it has three varients and are used for single Process ContU (node) configuration. 1. CPM01 (it only has round 5 pin connector on front that is interfaced with CTT i.e. Configuration and Tuning Terminal e.g CTT01). This varient has no option to connect...

I am not aware of any method to connect NCMP01 with computer.

What is this hand held terminal model number? Never worked with that. Seems like the controlway and infi90 loop is not used in your case. Composer with computer can be used when MFP is connected to controlway and controlway is connected to infi loop via NIS/NPM. Computer having composer is...

Moreover, as per attached picture I can see rack is starting from IMDSI. I havent seen first card in PCU as I/O card. I/O cards come after the MFP as MFP is has its expander bus and I/O cards are attached to this expander bus. Expander bus is on the downstream side of MFP.Can you elaborate, please?

Seems like you have single PCU with single redundant MFP. I have few more questions to understand the topology 1. Do you use HMIs? Are they OIS or computer based? If computer based which software are you using? 2. Every DCS manufacturer has its own proprietary and licensed engineering software...

Can you share the network topology? Do you have EWS and the composer (engineering software)?

ControsGuy25, There aren't any frozen screens on HMI. WTF, Your explanation was very good. Thanks for sharing. 1. Terminals PTBA -3 & -4, and -7 & -8 and -11 & 12 are neither used nor shorted on our site. We will do that on next available opportunity. 2. The jumpers from Q to P core are...

ControlsGuy25 Can you share or provide more details on the sentence that you wrote : "However, as L14HR is toggling randomly and before 24 hours the timer (T62CD) for L62CD gets reset, therefore, we are unable to stop the ratcheting unless we force L62CD. " L14TV1 is used for speed logic...
