FB_MBUS_JAN_UMG96S

This block is used to read electricity meters from Janitza:

-UMG96S

The block can only be executed together with the block FB_MBUSKL6781().

Functionality of the 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 meter to be read with this block.

stSecAdr: Secondary address of the meter to be read with this block (see ST_MBUS_SecAdr).

bStart: A positive edge of this input triggers one reading of the meter.

bSND_NKE: TRUE initializes the meter for each read operation and sets the meter to the first telegram (SND_NKE).

bReadInit: If the PLC is restarted, the meter is read once.

tMinSendTime: Standard 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: Unit of the energy values to be output by the block. 0=W(h) / 1=KW(h) / 2 =MW(h) / 3=GW(h).

bDisabled: TRUE = deselection of the block.
