Comau C4G Robot Communication Protocols

Paolo · Jan 12th 2023

Hello everyone. I urgently need to know what communication protocols are present on the Comau C4G Robot Controller.

I am attaching pictures of the Robot model.

It is a C4G RCC3

Serial Number 2008-6057

Model NM 45-2.0

Version SW TP 2.23

Version SW C4G 3.23

Thank you very much

Can anyone help me?

As far I can remember, the common protocols were:

DeviceNet

Profibus-DP

Interbus-S

All of them needing their own dedicated hardware.

C4G also have an Ethernet port (regular Ethernet, not Ethernet/IP)

But if You want to need to know the protocols present in this particular robot, You need to check System or IO secions on Main menu, I think.

I don't remember the path right now.

Hi, this regular Ethernet port (not Ethernet IP), what communication protocol does it use to communicate with the outside world?

massula · Jan 16th 2023

it was used normally for FTP communication, but I think You can do fancy stuff with tcp/ip and some advanced pdl2 skills.

Paolo · Jan 16th 2023

So a ModBus protocol?

massula · Jan 18th 2023

I don't think so.

I don't remember seeing mentions to Modbus-TCP, Ethernet/IP or other Ethernet based industrial protocols on C4G documentation. Just regular TCP/IP.
