Application.OpenForms is collection which contains all open forms in application. Here we check that form Arret618 is opened or not. If it is not found in OpenForms collection then we open it. If your problem solved then select correct answer.

public void READDM2() { string dm_position = 3030; UInt16 dmval = 0; try { if (!plc1.ReadDM(Convert.ToUInt16(dm_position) ref dmval)) { throw new Exception(plc1.LastError); } vitesseVal.Text = dmval.ToString(); if (vitesseVal.Text == 0) { bool isOpen = false; foreach (Form frm in Application.OpenForms) { if (frm.Name ==  Arret618 ) { isOpen=true; } } if(!isOPen) { Arret618 ss = new Arret618(); ss.Show(); } timer2.Stop(); timer3.Stop(); } } catch (Exception ex) { MessageBox.Show(this ReadDM() Error:  + ex.Message); }

In which event do you call method READDM2().
