• PLC Type: 90/30 or 90/70.
• Level 2 password: PLC write access authentication password.

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 SNP network. They can be addressed from 1 to 247 for serial nodes, or 0 to 255 for TCP/IP 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 SNP network (default is com1).
Ex: com1;1

Points Configuration

The syntax for the SNP communication points are:

• %<Operand><Address>

Operand: Indicates the memory area, the valid values are:

Address: Indicates the data address in the memory area.

Ex: %R00001 (Operand = R, Address = 1)
