Transducer Block (Primary)
Transducer blocks connect function blocks to local input/output functions. They read sensor hardware and write to
effector (actuator) hardware.
Transducer Block (Primary) Parameters
D Read/Write Capability: RO ‐ Read Only, RW ‐ Read Write
D Mode: The block mode(s) required to write to the parameter
D Double indentation and shaded Index Number indicates sub‐parameter

Static Revision
ST_REV
1 RO NA 0 to 65535 0
Data Type: Uint16
The revision level of the static data. Increments
by one each time a static parameter is written.
The value is reset to 0 whenever a Restart with
Defaults is performed.
