The ECOM Ethernet driver implements communication with Automation Direct (PLC Direct/Koyo) devices. It operates as a Master on the TCP/IP network. The communication blocks are dynamically created according to the pooling cycle defined on the AccessType for each Device Point.
Communication Driver Name: ECOM Ethernet
Implementation DLL: T.ProtocolDriver.Ecom.dll
Protocol: TCP
Interface: TCP/IP
PLC types supported: Automation Direct (PLC Direct/Koyo)
Communication block size: User configurable. The default is 255
Protocol Options: None
Multi-threading: User configurable. The default is one thread for each network node
Max number of nodes: User defined
PC Hardware requirements: Standard PC Ethernet interface board
Supported Operands:
| Operand | Address Range | Read | Write | Data Type | Address Size |
|---|
| C Control Relays | 0–1777 | Yes | Yes | Bit | 1 bit |
| CT Control Status | 0-177 | Yes | Yes | Bit | 1 bit |
| SP Special Relays | 0-777 | Yes | Yes | Bit | 1 bit |
| S Stages | 0-1777 | Yes | Yes | Bit | 1 bit |
| T Timer Status | 0-377 | Yes | Yes | Bit | 1 bit |
| Y Output Points | 0-777 | Yes | Yes | Bit | 1 bit |
| X Input Points | 0-777 | Yes |
| Bit | 1 bit |
| V Memory | 0-41237 | Yes | Yes | Word | 2 bytes |
Channel Configuration
Protocol Options
BlockSize: Defines the maximum amount of items per group. The default value is 255
Settings
TCP/IP:
NodeConnections: Defines the maximum number of parallel requests that will be sent to each node (asynchronous communication)
Node Configuration
Station Configuration
SlaveId: Set this field with the address of the slave device in the Network (PLC ID)
TCP/IP:
Station syntax: <IP address>;<Port number>;<Slaveid>
Where:
- <IP address> = The IP address of the slave device in the network
- <Port number> = The TCP port where the slave device is listening (default is 28784)
- <Slaveid> = The PLC ID in the Network (default is 1)
Ex: 192.168.1.101 ; 28784; 1
Point Configuration
The syntax for the ECOM communication points is: <Operand Type><Octal Address>
Where:
- <Operand Type> indicates the memory area:
- C Control Relays
- CT Control Status
- SP Special Relays
- S Stages
- T Timer Status
- Y Output Points
- X Input Points
- V Memory
For more information about the valid operands, see Supported Operands
- <Octal Address> indicates the data address in the memory area (octal format: 0 - 7)
Ex: V0 (Operand = Memory, Address = 0)
Troubleshoot
The status of the driver's execution can be observed through the diagnostic tools, which are:
• Trace window
• Property Watch
• Module Information
The above tools indicate if the operations have succeeded or have failed. A status of 0 (zero) means communication is successful. Negative values indicate internal driver errors, and positive values indicate protocol error codes.
