Unable to retrieve device list from the master

pauljloz

Anyone encountered this problem?

After adding a AXB-TMC (v2.11) to the AXLINK bus, when using Open Access 1.12 (Build 4) I encounter the message:

"Unable to retrieve device list from the master. Please confirm (connection active) and (master version is 3.90 or higher)."

Removing the AXB-TMC (v2.11) from the AXLINK bus allows normal operation of Open Access.

Other devices are an AXCENT3 Pro (v4.90) and a PC4 (actually a CPI16) (v2.10).
Netlinx Studio lists all items correctly and IREdit work fine uploading to the TMC.

Is this related to the Axcent3 firmware version?

Thanks

The only time I have seen this particular error was when there was something wrong with the AxLink buss - shorted pairs on the cable, a bad device, or just plain mis-wired.

This error can be replicated using a known good cable and with only the TMC on the AXLINK bus.

The device otherwise appears to function OK.

I'd venture to say the TMC is bad. Have you tried it on another master?
