100 Simulation inputs active
The fault message remains active until "Simulation" is returned to "----". This is to
make certain it will not be forgotten on the plant to reset the simulation.
The simulated input terminal value is used only locally; it is not sent via bus to
other controllers.
7.1.5

Troubleshooting

With some of the function blocks, defined inputs are mandatory, such as the
outside temperature. For this reason, when making a configuration, the input
identifiers must always be set first.
If input identifiers are changed after configuration of other function blocks, certain
functions for the other blocks may be set to inactive, as they would have to work
with units invalid for the particular block.
