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;
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..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.

bDisabled: TRUE = disable the function block.
