MODBUS interface:

• Transmission technology (Physical Layer): RS485 in accordance with ANSI/TIA/EIA-485-A:

1998, galvanically isolated

• MODBUS device type: Slave

• Adress range: 1...247

• Bus address adjustable via miniature switches or local display (optional) at the measuring device

• Supported MODBUS function codes: 03, 04, 06, 08, 16, 23

• Broadcast: supported with the function codes 06, 16, 23

• Transmission mode: RTU oder ASCII

• Supported baudrate: 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 Baud

• Response time:

Direct data access = typically 25...50 ms

Auto-scan buffer (data range) = typically 3...5 ms

• Available output combination → Page 7 ff.

FOUNDATION Fieldbus interface:

• FOUNDATION Fieldbus H1

• Transmission technology (Physical Layer): IEC 61158-2 (MBP), galvanically isolated

• ITK version 4.01

• Current consumption: 12 mA

• Error current FDE (Fault Disconnection Electronic): 0 mA

• Bus connection with integrated reverse polarity protection

• Function blocks: 5 x analog input, 1 x discrete output, 1 x PID

• Output data: volume flow, calculated mass flow, temperature, totalizer 1...3

• Input data: positive zero return (ON/OFF), reset totalizer

• Link Master (LM) functionality is supported

Signal on alarm • Current output → failure response selectable (e.g. in accord. with NAMUR Recom. NE 43)

• Pulse/frequency output → failure response selectable

• Status output (Promag 50) → non-conductive by fault or power supply failure

• Relay output (Promag 53) → de-energized by fault or power supply failure

Load See “Output signal”

Switching output Status output (Promag 50, Promag 53):

Open collector, max. 30 V DC / 250 mA, galvanically isolated.

Configurable for: error messages, Empty Pipe Detection (EPD), flow direction, limit values.

Relay outputs (Promag 53):

Normally closed (NC or break) or normally open (NO or make) contacts available

(default: relay 1 = NO, relay 2 = NC),

max. 30 V / 0.5 A AC; 60 V / 0.1 A DC, galvanically isolated.

Configurable for: error messages, Empty Pipe Detection (EPD), flow direction, limit values, batching contacts.

Low flow cutoff Switch points for low flow cutoff are selectable

Galvanic isolation All circuits for inputs, outputs, and power supply are galvanically isolated from each other.
