Safeguard configuration file
I have a question regarding the Safeguard 400 configuration file. So, we are working on a project where we'll replace the existing Safeguard 400 Dual System with redundant AC800M HI. The replacement will be done online while the plant is running and we will move/rewire each IO signal from safeguard termination/connection units to AC800M IO modules (signal by signal). So to be able to do this, we will have to make Inhibit/Block Input/Block Output for each Safeguard signal, untill finally all signals will be moved to AC800M HI. I have been analyzing the Safeguard Configuration file (which I'm sending in the attachment) for the controller to be replaced. Regarding the bypass managment, I've noticed this configuration code: .bypassm 0, (), '', '', 0, 00000, 0, 0, 0, 0, 0, ''; As I've conluded by this configuration parameters, there are no bypass restrictions applied to this Safeguard Controller. Only one parameter called "No_of_override" is concerning me. This parameter is set to 0, and 0 means "no override allowed". So as I see it according to this configuration file, no signal is allowed to be inhibited/bypassed by operator station. Am I right? But on site the operators can activate inhibits/bypasses from the operator stations. Does anyone know what's the catch?
Thanks in advance,
