A member of the congregation must be debarred from the meeting for two weeks after the police failed to perform a breath test.
Rhianon Passmore, Laboratory AM for Islwyn was convicted for failing to provide a breath sample for analysis.
She was fined £ 1,000 and asked to pay a fine of £ 100 for victims and £ 620 for judges for 20 months.
The incident occurred on September 23, 2017, and she appeared in court the following February.
In her statement to the European Commissioner for Standards, she said that she left the assembly last Friday at 7 pm.
Leaving her car in the parking lot of the congregation, she met a friend in Cardiff where they had dinner and Mrs. Passmore had two or three glasses of wine.
She returned to the congregation to pick up her car and was to travel to England, where she had booked a pre-booked trip and a hotel for which she had already paid.
In March, when she approached the Standards Commissioner, she made the following statement: "I left my car in the parking lot of the meeting and took a taxi to Cardiff to attend a previously arranged meeting with a friend.
"We talked about some important topics and consumed a meal and possibly two or three glasses of wine.
"I went back to the rally to pick up my car, but on the way I suffered from an asthma attack, I suffered from chronic and acute asthma exacerbations, and when I got to my car, I took emergency meds I carried with me.
"I immediately took my emergency presbyontal medication for acute asthma episodes as I was very short of breath. (I have emergency medications in addition to inhalers to treat my life-threatening chronic asthmatic exacerbations.) I am eligible to take an emergency steroid prednisone pack for acute episodes.
"As a chronic asthmatic, I wear a pill form of steroid emergency medication and carry a steroid license that lists my medications for healthcare professionals when they are episodic.
"This is necessary because of the sudden and potentially deadly nature of my condition.
"I decided to drive to my mother's house, but in St. Mellon my car broke down, I went to a parking lot and called the AA, the car did not start and this was verified by the independent garage waiting for the arrival of the AA came to the police.
"The police asked me to give them a respite, but I tried, but could not, and I was arrested and taken to the police station, where I was asked to give a breath sample for analysis.
"Again I tried, but I could not do it, and that was the basis of the charges that I found guilty."
She turned to the Commissioner for Standards after the conviction.
The Commissioner confirmed that this was a violation of the Code of Conduct for Members of the Assembly and that their conduct had discredited the Assembly.
The Standards Committee met twice to discuss the case and recommended a two-week cut-off time, starting on the first day after the summer break.
Ms Passmore wrote to the Commissioner, saying: "I deeply regret that I have violated the Code in this way and I sincerely apologize for it.
"I do not know why I was not able to give a sample of my breath, I did not deliberately miss it, and maybe my asthmatic condition contributed to my failure.
"During the trial, I was very desperate and this was exacerbated because, despite my illness, I could not access my medication.
"When my asthma medication was finally offered, I was prevented from taking the required and necessary dose.
"I believe that this and the fear of my condition went untreated and, in addition to being shocked after the attack, helped me to be unable to provide a sample as needed.
"I was later taken to the hospital by ambulance.
"A doctor was called to the police station to investigate my condition, and the doctor gave me oxygen and called an ambulance to take me from the police station to the hospital.
"On the way to the hospital I was put on a drip after the medication and I was held in the hospital until Saturday afternoon."
She once again apologized for her violation of the Assembly's Code of Conduct.
