Overview
Communication with devices compatible with SNP protocol.
Communication Driver Information | |
|---|---|
Driver name | 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, PACSystem and VersaMax. |
Interface | Serial and MultiSerial |
SNP (Series Ninety Protocol) was created by GE Fanuc Automation (GE + Fanuc). Later the brand became GE Intelligent Platforms, and today the PLC line (PACSystems/VersaMax) is with Emerson.
Supported Operands
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 |
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)
