Summary

ECOM Ethernet driver implements communication with Automation Direct (PLC Direct/Koyo) device. It operates as a Master on the TCP/IP network. The communications blocks are dynamically created according the pooling cycle defined on the AccessType for each Device Point.

Channels 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

Primary Station 

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> = IP address of the slave device in the network
  • <Port number> = TCP port where the slave device is listening (default is 28784)
  • <SlaveId> = PLC ID in the Network  (default is 1)

E.g.:  192.168.1.101 ; 28784; 1


Points 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, refer to the Supported Operands aforementioned:

  • <Octal Address> indicates the data address in the memory area (octal format, 0 - 7)

E.g.: V0 (Operand = Memory, Address = 0)
