Relay Switch of Stepper Motor Driver

I tried to turn the relay switch of the stepper motor driver ON/OFF by operating the BIO of the EPICS channel.
After the change to ON/OFF, a ping test was performed to confirm that the relay switch was working.
The investigation was carried out before the 15845 and 15839 operation.

On/Off was performed normally:.
PR2_GAS, PR0_GAS
ITMX_GAS, ITMX_IP
ETMX_GAS, ETMX_IP
ITMY_GAS, ITMY_IP

Switched between ON and OFF, but did not change to ON state.
ETMY_GAS
BS_GAS
BS_IP
SR2_GAS
SR2_IP
SR3_GAS
SR3_IP
SRM_GAS
SRM_IP

Switched between ON and OFF, but did not change to OFF state.
ETMY_IP

We investigated the relay switch of the stepper motor driver because it did not work.

The TEST toggle switches for both BS, SRM, SR2 and SR3 were turned on.
Therefore, I could not operate from the EPICS channel, so I turned off all TEST toggle switches once.

I also put a "Turn off if use BIO" label next to the toggle switch.

The following situations were different.

SRM, SR3:
When changed to OFF, the relay switch operated normally from the EPICS channel.
K1:VIS-SRM_BIO_ENCODE_STEP_IP_SW
K1:VIS-SRM_BIO_ENCODE_STEP_GAS_SW
K1:VIS-SR3_BIO_ENCODE_STEP_IP_SW
K1:VIS-SR3_BIO_ENCODE_STEP_GAS_SW

SR2:
The relay switch was connected to IP and GAS in reverse.
We checked the model and confirmed that the actual connections and the wiring in the model are reversed.
To match the model, we swapped the IP and GAS connections and confirmed that it works correctly.
K1:VIS-SR2_BIO_ENCODE_STEP_IP_SW
K1:VIS-SR2_BIO_ENCODE_STEP_GAS_SW

BS:
The relay cable was connected correctly, but could not be operated from the EPICS channel.
K1:VIS-BS_BIO_ENCODE_STEP_IP_SW
K1:VIS-BS_BIO_ENCODE_STEP_GAS_SW
After investigation, there was no connection between the Binary In/Out Converter and the I/O Chassis.

The cable for BS was not connected as Ikeda-san said.
Today I found it was connected to the BIO cheker board. So, I connected the cable to the stepper driver circuit.
After connecting the cable, I confirmed that web page of the Nport for BS-GAS and BS-IP could be seen from web browser.
