How can I prevent unauthorized operators changing parameters (without removing the BOP)?
There are two methods of locking the parameters:Method 1: Using Parameter P0927.Parameter P0927 defines how the user is able to change parameters. It governs whether parameters can be changed over each of the serial links or not.Setting a value of 0 prevents all parameters (except P0003, P0004, and P0927) from being altered from all sources.Other setting are available – see description for P0927 in the Operating Instructions.Note: P0927 is a binary parameter.Method 2: Using Parameters P0011, P0012 and P0013The purpose of P0013 is to define a user parameter set, which is easy to see. This prevents users accessing other parameters. Therefore by selecting no parameters in this set and applying the lock, access to all parameters is prevented.The setting of the lock, key and user set is described in the Parameter List in P0013, but to prevent access to all parameters set the following:P0003 = 3 P0011 = [ your pin number ] – this defines the lock or password for P0012 P0003 = 0 = this enable
