Thermo Fisher Scientific AutoPILOT PRO Flow Computer User Guide 10-9
The AutoPILOT PRO flow computer uses one communications port
definition block per serial port. The block can be used to specify the port as
a Master or slave. When in Master mode, the communications block
references contain pointers to any combination of the following types of
Master blocks:

Modbus master communications blocks – Read/Write Modbus
Data

Smart transducer communications blocks – Read Smart Transducer
Data

Chromatograph communications blocks – Read Gas Quality Data

Tank gauge communications blocks – Read Tank Gauge Data
When in slave mode, the communications block references contain
pointers to a list of Modbus slave communications blocks and optionally an
alarm callout block.
