BIO setting at IXV

Toward further step, I check and confirm that all the BIO system for the type-A suspension work properly except for the BO system for the IP and F0. The confirmed channel assignments are the following. I find BI signal and then, I send a state request on MEDM screen and checked if the BI signals are changed properly:

BIO card name	left (Binary Output)	right (Binary Input)
BIO-1 A	looks-Not-working	IP-F0
BIO-1 B	GAS	GAS
BIO-2 A	MN-Horizontal	MN-Horizontal
BIO-2 B	MN & IM-Vertical	MN & IM-Vertical
BIO-3 A	IM-Horizontal	IM-Horizontal
BIO-3 B	IM-Damping	IM-Damping
BIO-4 A	TM	TM
BIO-4 B	X	X
BIO-5 A	BF-LVDT-Horizontal	BF-LVDT-Horizontal
BIO-5 B	BF-LVDT-Vertical	BF-LVDT-Vertical

Still, it looks that BO system for the IP-F0 coil driver does not work well. I will try to put another BIO card and will see what will happen. If nothing happens, the I/O chassis which is currently housed at IXV would be replaced with the one at IYV.

Hi Fujii-kun,

I rewrote a part of real-time code related with BIO.
This problem was found and fixed by Rolf and Keith.

Please check again after rebuilding the models.

Hi Yamamoto-san...,

Thanks for that information and help. However, this issue has not gone away with that procedure. What I tested was:
rebuilding the iopmodel and the slave models in the real time machine (k1ix1), and then start the models. After this procedure,
- test1: I turned on the RT machine with 5 BIO cards -> The system looked fine (figure 1)
- test2: turned on with 6 BIO cards (after modifing the k1iopix1 model, so that, adding one DIO blck) -> The RT model started its run but the k1visitmx did not work properly. (figure 2)
- test3: turned on with 6 BIO cards with another BIO slot -> Both the iopmodel and the slave model did not work properly. (figure3)

I could not be away from a nightmare.

Probably DC power supply is not enough. You need a higher power supply.

We have a better AC-DC ATX power supply,

or you can use DC-DC power supply which will be used as default for all the KAGRA IO chassis.
