3.5.7 215IF Transmission Definitions
This section explains how to define the 215IF transmission system.
„ Outline of 215IF Transmissions
The 215IF transmission system is a unique real-time Yaskawa network with transmission
speed 4 Mbps. Twisted-pair cable is used for the transmission lines, so an inexpensive but
highly reliable transmission system can be constructed.
The settings required for 215IF transmissions are divided into four tab pages: The Parame-
ter Settings, Link Assignments, I/O Map, and Status Tabs.
There are two kinds of transmissions in a 215IF Transmission System: Link transmissions
and message transmissions. The required settings for the link transmissions are made here.
Link transmissions are repeated every cycle according to the settings made here. Message
transmissions are programmed in drawing/function programs using the MSG-SND and
MSG-RCV functions.
