As a dress rehersal for next weeks upgrade of all the IO Chassis, this afternoon we upgraded the FPGA firmware in the timing slave unit of h1pemmx.

We also used this to verify our set of procedures:

Prior to h1pemmx, we had upgraded three IO Chassis on the DTS. We wanted to do one H1 chassis to see what the Beckhoff timing system reported as a version number (not available on DTS).

All went well with no problems. The reported Rev number went from 0 to 100, which is expected. The current Beckhoff code does not recognize 100 as a valid number, hence the "Firmware error", this will be fixed next Tuesday.

We timed the procedure, it takes about 15 minutes per chassis.

The Beckhoff MEDM for h1pemmx slave is shown below
