CC-LINK IE FIELD NETWORK BASIC
COMMUNICATION
Since LE7-40GU supports the slave function of CC-Link IE Field Network Basic communication which is an open FA network,
it can communicate with various CC-Link IE field network Basic master stations.
Precautions
• Since CC-Link IE Field Network Basic uses port No. [61451] as a device detection port, when port No. [61451] is used for
another communication function, CC-Link IE Field Network Basic connection cannot be used.
• Since LE7-40GU handles a number of object functions besides the CC-Link IE Field Network Basic connection function,
the response performance with respect to access from the master station may deteriorate. In such a case, it is necessary to
adjust the link scan time or the timeout time on the master station side. The recommended setting value is 50 ms or more.
