8.10.2 Modes
The ARTHM block supports the following modes:
• Manual (Man): The block output (OUT) may be set manually.
• Automatic (Auto): OUT reflects the analog input measurement or the simulated
value when simulation is enabled.
• Out of Service (O/S): The block is not processed. FIELD_VAL and PV are not
updated, and the OUT status is set to Bad: Out of Service. The BLOCK_ERR
parameter shows Out of Service. In this mode, you can make changes to all
configurable parameters.
The target mode of a block may be restricted to one or more of the supported
modes.
