Quantum Ethernet Remote I/O

[PLCNorth]

I am looking for help in getting a Quantum PLC 140 CPU 651-30 running Ethernet Remote I/O. I have a 140 CRP 312 00 Ethernet Remote I/O head and one drop to a remote rack with a 140 CRA 312 00. The connection between the main rack and the remote drop is through single mode fibre, using two Connexium TCSESM063F2CS1C switches. I have downloaded the pre-defined configuration C5 to the switch at the main rack and configuration C3 at the remote rack. The remote I/O drop rotary switch is set to drop one. I am using Unity Pro XL version 6.0 software, which assigned an IP Address of 192.168.10.1 to the CRP and an address of 192.168.10.2 to the remote drop. The CRA does not seem to be getting its configuration on power up as I can ping the CRP, but not the CRA. Any suggestions would be appreciated.

extract from help file Setting Rotary Switches Set the location of the Ethernet remote I/O drop on the network with the rotary switches on the front of the 140 CRA 312 00 module before you apply power to the module and before you download the application: The values you set are applied during a power cycle. If you change the setting of the rotary switches after the module has powered up, the Mod Status LED is activated, and a mismatch message is logged in the module diagnostic. Because new values on the rotary switches are implemented only at the next power cycle, we recommend that you set the value before starting the module. (Valid values: 00 ... 159) The values on the rotary switches combine with the device prefix (for example, 140CRA_) to create the device name. The above figure shows the Tens switch set to 0 and the Ones switch set to 01, for a device name of 140CRA_001.

We relocated the remote rack so we were able to connect to to the main rack with Ethernet cables, which worked fine, the problem seems to be in the Connexium switch configuration.

When applying the pre-defined configuration to the Connexium switch, did you reset the switch to factory default first? The way those files work is that they only maintain the state of the changes versus a default configuration. There are many settings that could block traffic in the switch - including port security, VLANs, etc.
