Summary
Melsec-FX Ethernet communication driver implements communication with Mitsubishi FX Series PLCs using Melsec Q 1E frame. It operates as a Master on TCP/IP networks. The communication blocks are dynamically created according to the pooling cycle defined on the AccessType for each point.

Channels Configuration
Protocol Options
- Maximum size of blocks: Defines the maximum of addresses in a read block.
Settings
TCP/IP:
- NodeConnections: Defines the maximum number of parallel requests that will be sent to each node (asynchronous communication)
Nodes Configuration
Station Configuration
TCP/IP:
- Station syntax: <IP address> ; <Port number>
Where :
- <IP address>: IP address of the slave device in the modbus network
- <Port number>: TCP port where the slave device is listening (default is 5551)
E.g.: 192.168.1.1 ; 5551
Points Configuration
The syntax for the MelsecFX_Ethernet communication points is: <Operand> <Address>
Where :
- <Operand>: Represents the Device Memory :
- <Address>: Address number
