FB_MBUS_HYD_Sharky

FB_MBUS_HYD_Sharky 1:

The function block FB_MBUS_HYD_Sharky is used to read energy meters of the companies:

Hydrometer:

-Sharky 773

-Sharky 775

-ENERGY INT 6

Brunata:

-Brunata Optuna H (775)

Aquametro:

-AMNTRONIC SONIC D

Only the most common values (see "VAR_OUTPUT") of the telegrams:

00 ( Application Reset-Subcode 00 / All )
10 ( Application Reset-Subcode 10 / User data)
20 ( Application Reset-Subcode 20 / Simple billing)
30 ( Application Reset-Subcode 30 / Enhanced billing)
40 ( Application Reset-Subcode 40 / Multi tariff billing)
or 50 ( Application Reset-Subcode 50 / Instant values)

are read.

The device is not switched to these telegrams; it must be set to one of these telegrams.

The function block FB_MBUS_HYD_Sharky_00() can be used if further data are required, or the function block FB_MBUS_General_Send() can be used to select the required telegram, and the function block FB_MBUS_General() can be used to read all data of the respective telegram.

The function block can only be executed together with the function block FB_MBUSKL6781().

Name

Type

Description

usiAddress

USINT

Primary address of the meter to be read with this function block.

stSecAdr

ST_MBUS_SecAdr

Secondary address of the meter to be read with this function block.

eBaudrate

E_MBUS_Baudrate

300, 2400, 9600 baud

bStart

BOOL

All meters are read once on the positive edge of this input.

bSND_NKE

BOOL

TRUE initializes the meter for each read operation and sets the meter to the first telegram (SND_NKE).

bReadInit

BOOL

If the PLC is restarted, the meter is read once.

tMinSendTime

TIME

Default t#2s. The meter is read again, once the time set here has elapsed. If t#0s the meter is not read and can be read manually with bStart.

usiUnit

USINT

Unit of the energy values to be output by the function block. 0=W(h) / 1=KW(h) / 2 =MW(h) / 3=GW(h).

bDisabled

BOOL

TRUE = deselection of the function block
