Open settings for connection to the built-in Ethernet port of the MELSEC iQ-R series

Are open settings required to connect multiple GOTs to a single MELSEC iQ-R controller (built-in Ethernet port)?

Category : 

Answer

Open settings are required when the communication method of the GOTs is TCP for a single MELSEC iQ-R series controller (built-in Ethernet port). 
Configure the settings for [External Device Configuration] in GX Works3 for each connected GOT.

◆ For GX Works3
Go to the Navigation window then select → [Parameter] → [RnCPU] → [Module parameter] →
[Basic Settings] → [External Device Configuration] → [Detail settings] → [Ethernet configuration (built-in Ethernet port)]
Figure 1: When connecting two GOTs via TCP,

Open settings are not required when the communication method on the GOT side is UDP.
