NJ501 comunication problem

8 posts in this topic

Good Morning,

I new in Omron and I have a question.

I have PLC NJ501-1320 and Ethernet/IP module CJ1W-EIP21 in one rack.

My question is: Can I connect with PLC via CJ1W module? Because I cannot go online when I connect to port in CJ. The same problem, when I plug cable to plc port, I cannot ping CJ module. I read manuals but I saw only configuration, when CJ module read data from another device.

IP: PLC 192.168.250.1

     CJ1W 192.168.250.3

Thank's

Sysmac Studio uses undocumented HTTP to a private API to go online with the processor.  I don't think the add-on modules have that private API.

Hello
I have Omron NJ501-1320 and CJ1W-EIP21 on the same rack.
I would like to use EtherNet/IP port in PLC to connected to the database with totally diferent IP.

Port in CJ1W module I would like to connect with computer and go online or download software to plc and of coure connected with peripherals operating Ethernet/IP , but probably it isn't possible to upload a software via this module.

You can't use same subnet IP!

Do you mean the two IP addresses must be in separate subnets?  If so, I beg to differ.  I have a customer running this combination with both components in the same subnet.

From W506 CPU Unit Built-in EtherNet/IP™ Port:

Quote

For an NX701 CPU Unit and an NX102 CPU Unit, you cannot set IP addresses that make two
built-in EtherNet/IP ports belong to the same network.

He's not using two built-in EtherNet/IP ports.  He's using one built-in on the CPU and one on the CJ1W-EIP21 card.  (The NJ501 doesn't have two.  Its second ethernet port is EtherCAT only.)
