FB_MBUS_SEC_iEM3135
This module is used to readout electricity meters of the manufacturer Schneider Electric.
It can only be used together with the module FB_MBUSKL6781().
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.
