B&B Electronics RS-485 manual Set Digital Output Command, Set Module Address Command, AddrSOstates

Set Digital Output Command

The Set Digital Output command is used to set the states of the 3 digital output lines. This command requires a data byte. The data byte is used to specify the output states. Bits 0-2 correspond to the states of digital outputs 0-2. If a bit is a 0 then the output will be set LOW. If a bit is a 1 then the output will be set HIGH. Refer to Table 3.6. NOTE: This command ignores Bits 3-7 of the data byte.

Command Syntax

!{addr}SO{states}

Where {states} is a byte in which Bits 0-2 correspond to the outputs states of Digital Outputs 0-2

Unit Response no response

Table 3.6 - Set Digital Output Data Byte Values

	Data Byte			Digital Outputs
Bit 2	Bit 1	Bit 0	#2		#1	#0
0	0	0	LOW		LOW	LOW
0	0	1	LOW		LOW	HIGH
0	1	0	LOW		HIGH	LOW
0	1	1	LOW		HIGH	HIGH
1	0	0	HIGH		LOW	LOW
1	0	1	HIGH		LOW	HIGH
1	1	0	HIGH		HIGH	LOW
1	1	1	HIGH		HIGH	HIGH

Set Module Address Command

The Set Module Address command is used to change the address of a 485SDA10. This command requires a data byte. The data byte is used to specify the new address of the unit. The address of a module is stored in non-volatile memory.

Command Syntax

!{addr}SA{new address} Response Syntax

no response

Where {addr} is the current address of the module and {new address} is a byte representing the new address.
