Snp

Assembly Name

T.ProtocolDriver.Snp

Assembly Version

1.0

Available for Linux

False

PLC types supported 

GE Fanuc PLCs - 90/30 and 90/70 Series

Interface

Serial and MultiSerial


Channels Configuration

Protocol Options

  • BlockSize: Defines the maximum amount of items per group, the default value is 1000.
  • 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:

AI

Analog Input

AQ

Analog Output

G

Discrete Global Memory

I

Discrete Input

Q

Discrete Output

T

Output (Temporary) Coils

M

Internal Coils

S

System Status

R

Register Memory

Address: Indicates the data address in the memory area.

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


Troubleshoot

The status of the driver execution can be observed through the platform built-in diagnostic tools. Refer to the Using Diagnostic Tools topic in Devices Communication page.
