Strange way of working

Hello,

Has anybody else been thinking about, how differently regulations expect system integrators
to provide system documentation to the end-users? Detailed electric schematics shall be
provided in order to enable customers troubleshoot their traditional discrete instrumentation
and power supply network. But, after asking from numerous companies, nobody knows requirements
to provide signalling over field buses or other kind of control networks. In modern world, the
all signals are updated over some kind(s) of network(s), which makes communication databases
modern supplements to the electric schematics.

Is there a trend allowing system integrators to hide signalling and disable troubleshooting
with off-board tools or have people just forgot to state a requirement to open the most
essential part of network signaling for field-service? Nobody can state that typical sensor
and actuator interface signals are secret, because their function can be mostly understood by
just looking the operating system.

Best regards,

-H
