Uploading Program Through Serial From Another PLC

[JustinSmith]

Hello,

We have a FX3G connected to a FX3U-ENET-ADP inside a main cabinet. We are then using that master PLC to collect data from 2 other fx3g plcs in a node:node serial network. I was assigned a small project of pricing out some wireless adapters so we can upload/download to the two slave plcs. My question is, is it possible to upload/download programs to/from the slave plcs through the ENET adapter and serial network in the main plc? It would save us some money if possible.

thanks.

The ENET-ADP can be used for programming in my experience.  But no, you cannot transfer a program to one PLC routing through another.  You need to connect directly to a PLC to program it.
