FB_MBUS_HYD_Sharky_00
This function block is used to read energy meters from:
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 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().
Functionality of the function block
VAR_INPUT
usiAddress : USINT;
stSecAdr : ST_MBUS_SecAdr;
eBaudrate : E_MBUS_Baudrate := eMBUS_Baud2400;
bStart : BOOL;
bSND_NKE : BOOL := TRUE;
bReadInit : BOOL := TRUE;
tMinSendTime : TIME := t#2s;
usiUnit : USINT;
bDisabled : BOOL := FALSE;
usiAddress: Primary address of the counter, that shall be readout with this module.
stSecAdr: Secondary address of the counter, that shall be readout with this module.
eBaudrate: 300, 2400 baud.
bStart: Positive edge on this input, the meter is read out once.
bSND_NKE: TRUE to initialize the meter at each reading, and sets the meter on the first telegram (SND_NKE).
bReadInit: After restarting the PLC, the meter is read out once.
tMinSendTime: Standard t#2s. When this time exceeds, the counter is rereadout. At t#0s the counter is not readout and can be readout with bStart manually.
usiUnit: Unit of the energy values. 0=W/J(h) / 1=KW/KJ(h) / 2=MW/MJ(h) / 3=GW/GJ(h).
bDisabled: TRUE = disable the function block.
