Name | Type | Description |
---|---|---|
usiAddress | USINT | Primary address of the meter to be read with this function block. |
stSecAdr | Secondary address of the meter to be read with this function block. | |
eBaudrate | 300, 600, 1200, 2400, 4800, 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 |
