Specifications and Functions
( 2 ) Specification of 218IFA Module
The following table shows the specification of the 218IFA Module.
* 1. Communication Interface
The discrimination between 10Base-T/100Base-TX and full-duplex/half-duplex is done by the 218IFA module
based on the remote equipment. When connecting to an equipment without automatic negotiation function, set the
remote equipment to half-duplex mode.
* 2. Communication protocols
• TCP (Transmission Control Protocol): Connection-oriented transport layer protocol
• UDP (User Datagram Protocol): Connectionless transport layer protocol
• IP (Internet Protocol): Protocol for establishing a communication link between computers
• ICMP (Internet Control Message Protocol): Error control protocol for IP protocol
• ARP (Address Resolution Protocol): Address resolving protocol. Protocol for converting IP address into MAC
address
* 3. Non-procedure Receive Buffer Mode Selection
When the non-procedure application protocol of the 218IFA is used, either a single buffer or multiple buffers can be
selected for the receive buffers in the 218IFA.
If multiple buffers are selected, 20 data items per connection can be processed at the same time with data contin-
