S - Output Octet | Yes | Yes | Yes | Yes | Byte | 1 byte |
A - Auxiliary | Yes | Yes | Yes | Yes | Byte | 1 byte |
M - Memory | Yes | Yes | Yes | Word | 2 bytes | |
I - Integer | Yes | Yes | Yes | DWord | 4 bytes | |

Channels Configuration
Protocol Options
BlockSize: Defines the maximum amount of items per group, the default value is 512.
Node: Computer node address in the Alnet network. Default value: 1 (Used only to unsolicited messages)
SubNetwork: Alnet subnetwork. Default value: 0 (Used only to unsolicited messages)
Nodes Configuration
Station Configuration
IP: IP address of the target PLC station in the Alnet network.
Port: IP Port used in the Alnet II communication. Default value: 405 (Read Only)
: Station uses 4 semicolon-separated fields: `
- DestCpNode;
- DestCpSubNet;
- OriginCpNode;
- OriginCpSubNet`.
- These are **required** for Alnet I network routing. The DestCpNode is typically derived from the last octet of the PLC IP address. DestCpSubNet defaults to 64.
Points Configuration
The syntax for the Alnet communication points are:
- %<Operand><Address>
Operand: Indicates the memory area, the valid values are:
Operand | Read | Write | Bit Read | Bit Write | Data Type | Address size |
|---|---|---|---|---|---|---|
E - Input Octet | Yes | Yes | Yes | Yes | Byte | 1 byte |
S - Output Octet | Yes | Yes | Yes | Yes | Byte | 1 byte |
A - Auxiliary | Yes | Yes | Yes | Yes | Byte | 1 byte |
M - Memory | Yes | Yes | Yes | Word | 2 bytes | |
I - Integer | Yes | Yes | Yes | DWord | 4 bytes | |
D - Decimal | Yes | Yes | Yes | LBCD | 4 bytes | |
F - Real | Yes | Yes | Single | 4 bytes |
Address: Indicates the data address in the memory area.
Ex: %E0000 (Operand = E, Address = 0)
- %<Operand><TableId>[TablePosition]
Operand: Indicates the memory area, the valid values are:
Operand | Read | Write | Bit Read | Bit Write | Data Type | Address size |
|---|---|---|---|---|---|---|
TM - Memory Table | Yes | Yes | Yes | Word | 2 bytes | |
TI - Integer Table | Yes | Yes | Yes | DWord | 4 bytes | |
TD - Decimal Table | Yes | Yes | Yes | LBCD | 4 bytes | |
TF - Real Table | Yes | Yes | Single | 4 bytes |
TableId: Indicates the table memory area.
TablePosition: Indicates the position in table memory area.
Ex: %TM0001[2] (Operand = TM, TableId = 1 TablePosition = 2)
