FB_MBUS_HYD_Sharky_00

The function block FB_MBUS_HYD_Sharky_00 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

All values of telegram 00 ( application reset subcode 00 / All ) are read. The device automatically switches to the corresponding mode.

stPulsecounter1 and stPulsecounter2 are only output if the pulse module is connected.

If further telegrams are required, the desired telegram can be selected with the function block FB_MBUS_General_Send() and all data of the respective telegram can be read with the function block FB_MBUS_General().

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
