Work on Acromag chassis |

Now that the .db files were prepared, I wanted to test for errors. So I did the following:
- Acromags were mounted on the DIN rails. Attachment #1 shows the grouping of ADC, DAC and BIO units. They are labelled with their IP addresses.
- Wiring of power:
- Chub had already prepared the backplane with the power connectors, switches and indicator LEDs.
- So I just had to daisy chain the +24 V (RED) and GND (BLACK) terminals for all the acromags together, which I did using 24 AWG wire (we may want to use heavier gauge given the current draw).
- Ethernet cables were used to daisy chain the network connectivity between the various units. Attachment #1 shows the current state of the chassis box.
- Front panel pieces were attached and labelled, see Attachment #2.
- I found it was sufficient to use the front - we may use the rear panel slots when we want to add connections for controlling the c1aux machine channels.
- The D15 P2 connector panel for the CM board will arrive tomorrow and will be installed then.
- Entire setup was connected to power and ethernet, see Attachment #3.
- As usual, the current draw is significant for the collection of Acromags, I got around this problem by using the bench supply to "Parallel" mode to enhance the current driving capacity.
- For the ethernet connection, I used the office space port #6, which I connected at the network rack end to the eth1 port of the Supermicro.
All the Acromags are seen on the 192.168.114 subnet on c1iscaux3 - however, when I run the modbusIOC process, I see various errors in the logfile , so more debugging is required. Nevertheless, progress.
Update 2245: Turns out the errors were indeed due to a copy/paste error - I had changed the IP addresses for the ADCs from the .115 subnet c1susaux was using, but forgot to do so for the DACs and BIOs. Now, if I turn off the existing c1iscaux so that there aren't any EPICS clashes, the EPICS server initializes correctly. There are still some errors in the log file - these pertain to (i) the mbbo notation, which I have to figure out, and (ii) the fact that this version of EPICS, 7.0.1, does not support channel descriptions longer than 28 characters (we have several that exceed this threshold). I think the latter isn't a serious problem.
Getting closer... Note that I turned off the c1iscaux VME crate to prevent any EPICS server clashes. I will turn it back on tomorrow. |
