EL6688

EL6688

• missing epics db template ecmcEL6688.substitutions
• should the salve default to DHCP?
• the hardware default is PTPv1, this should be set to PTPv2 during startup.

@anderssandstrom
How do you operate the EL6688 at ESS? static IP and PTPv1?

The issue with this slave is that certain SDOs need to be set at the state machine transition I->P.
@anderssandstrom
do you know whether the IgH master has this feature?
The current workaround is is to set the respective SDOs and write the current settings to the EEPROM of the slave, followed by a power cycle.
With this procedure, DHCP and PTPv2 work as intended.

[anderssandstrom]

@kivel, no I don't think you can add any settings automatically at I->P but I will investigate a bit.
Have only tested without ptp master so my knowledge is rather limited on this slave.
So, is the timeDc01 and timePtp01 giving correct values for you?
Next step is to sync the clocks I guess. Can we do that with some setup of chrony you think?!
Or handle in ecmc would also be possible.

@anderssandstrom, So far I only checked that something arrives in the respective time registers. Whether those numbers make sense is a different story.
How to proceed with synchronization is a completely different topic. But, currently, I'd focus on the motion part of ECMC.
For the EL6688, I'd go on with the procedure of setting up the SDOs manually and burn them to the EEPROM. It only has to be done once, and nothing should change later.

• add dedicated PTP section to documentation
• document the procedure for burning the settings into EEPROM.
• add a feature to check for PTPv2 and DHCP enabled during startup with option to fail.
