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, 9600 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.
