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
