Channels Configuration
Protocol Options
- BlockSize: Defines the maximum of addresses in a read block. Default is 255.
- Format: Available options: Format1, Format2, Format3 and Format4.
Settings
- Serial and MultiSerial channels:
Default configuration:
DataBits: 8.
StopBits: 1 if parity is used, 2 if no parity.
Set the other fields according to your Serial or MultiSerial port configuration.
Nodes Configuration
Station Configuration
SlaveId: Set this field with the address of the slave device in the network. They can be addressed from 1 to 247 for serial nodes. The address 0 is used for the broadcast.
- Serial channels:
Station syntax: <SlaveId>
Ex: 1
- MultiSerial channels:
Station syntax: <ComPort>;<SlaveId>
Where : <ComPort> = COM Port of the slave device in the network (default is com1).
Ex: com1;1
Points Configuration
The syntax for the MelsecA communication points is: <Operand> <Address>
Where :
- <Operand>: Represents the Device Memory :
- <Address>: Address number
