Device part of <Figure 1> input Com Port(COM1), Baud Rate(9600), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively.
BS4800A communication driver’s read schedule
Read schedule setting parameters are as follows:
1) STATION – Don't care.
2) Read command – Don't care.
3) Read start address –Don't care.
4) Save start address for Communication Server – Saving start address of Communication Server.
5) Read Size – Size = Fix to 1.
Read schedule example)
READ, 0, 0, 0, 0, 1,
Note) BS4800A controller can set baud rate 2400 ~ 9600bps.
BS4800A communication driver save readed data as follows.
WORD memory)
address 0 = BIT 3 : Empty Relay, Bit 2 : Low Relay, BIT 1 BIT : High Relay, BIT 0 : stability of weight.
address 1 = BIT 0 : when Start, Stop switch operation - ON, else - OFF.
DWORD memory)
address 0 = present weight value.
address 1 = Low setting value.
FLOAT memory)
address 0 - present weight value.
address 1 - Low setting value.
You can change the setting values of BS4800A Controller BC410 by using write settings.
Bit Write
Bit write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Don't care.
3) ADDRESS Don't care.
4) Extra1 Write command = UAST, UMST, USTP.
5) Extra2 Don't care.
Write example 1)
PORT : 0 STATION : 0 ADDRESS : 0000 EXTRA1 : UAST EXTRA2 : 0
The setting parameter shown above is an example of bit write for 'START' of BS4800A connected with 0 port.
Word Write
Word write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Don't care.
3) ADDRESS Don't care.
4) Extra1 Write command = UAST, UMST, USTP, UL.
5) Extra2 Don't care.
Write example 1)
PORT : 0 STATION : 0 ADDRESS : 0000 EXTRA1 : UL EXTRA2 : 0
The setting parameter shown above is an example of word write for 'LOW' value setting of BS4800A connected with 0 port.
