System Configuration for Digital Output (DE Output)
System
configuration Figure 1-5 shows a system configuration in which the flow rate measured by
the unit, the database in the unit, and self-diagnostics are output using the DE
(Digital Enhancement) protocol (rules for digital signal communication).
In this system, the DE protocol-based digital signal transmitted from the unit
is output to the control system after conversion to an analog signal at the smart
protocol converter (SPC). Or, the digital signal is directly transmitted to the
control system, if it is capable of receiving the DE protocol-based signal di-
rectly.

system
• Smart electromagnetic flowmeter (device): Measures the flow rate and out-
puts the instantaneous flow rate and unit self-diagnostics using a digital
signal.
• Smart protocol converter (SPC): Converts the DE protocol-based digital
signal into a 4 - 20 mA or 1 - 5 V DC analog signal for output.
• Smart handy loader (SHL): Used to change the SPC settings.
• Smart communicator (S-SFC): Used to communicate with the device to
read data and change the device settings.
• PM100: Simultaneously executes such functions as process control on the
UCN, regulatory control, sequencing, calculation, and process input/out-
put.
